Answer:

8(y + 27) ≤ -15

Step-by-step explanation:

In the given inequality statement,  "Eight times the sum of a number and 27 is at most "-15""  

The first part, "Eight times the sum of a number and 27" means that 8 is multiplied to the sum of y and 27.  While the phrase "at most" means "less than or equal to (≤)"  The phrase also implies that the value of y can be -15, or any value less than -15.  

Therefore, the correct algebraic expression is: 8(y + 27) ≤ -15  

An equation in slope-intercept form for the line that passes through (9,12) and is parallel to y=4 is y= 4x -24.

What is Parallel lines?

Parallel lines in geometry are coplanar, straight lines that don't cross at any point. In the same three-dimensional space, parallel planes are any planes that never cross. Curves with a predetermined minimum distance between them and no contact or intersection are said to be parallel.

Parallel lines will have the same slope but different y-intercepts  so again we can  use the coordinates to determine the y intercept of the new equation.

So we know that the slope intercept formula is y=mx + b where m is the slope and b is the y-intercept so we will input the x and y coordinates to solve for b.

12 = 4(9) + b

12 = 36 + b

b = -24

The equation will be y= 4x -24.

The curve has horizontal tangents at the points (0,0) for all values of t. To find the points at which the curve has a horizontal tangent, we need to find the values of t that make the derivative of y(t) equal to zero.

First, we need to find the derivative of y(t):

y'(t) = 8cos(t)

Next, we set y'(t) equal to zero and solve for t:

8cos(t) = 0

cos(t) = 0

This occurs when t = π/2 or 3π/2.

Now, we can plug these values of t back into the original equations to find the corresponding points:

When t = π/2,

x(π/2) = 4cos(π/2) = 0

y(π/2) = 4sin(2(π/2)) = 0

So the point is (0,0).

When t = 3π/2,

x(3π/2) = 4cos(3π/2) = 0

y(3π/2) = 4sin(2(3π/2)) = 0

So the point is also (0,0).

The point on the curve where the tangent line is parallel to the plane is (-2sin(arccos(-a/2)), 2cos(arcsin(-b/2)), c).

To find the point on the curve r(t) = (-2sin(t),2cos(t),e^t) where the tangent line is parallel to the plane, we need to find the derivative of the curve and set it equal to the normal vector of the plane.

The derivative of the curve r(t) is:

r'(t) = (-2cos(t), -2sin(t), e^t)

The normal vector of the plane is (a,b,c).

To find the point where the tangent line is parallel to the plane, we need to set the derivative equal to the normal vector:

-2cos(t) = a

-2sin(t) = b

e^t = c

Solving for t, we get:

t = arccos(-a/2)

t = arcsin(-b/2)

t = ln(c)

Plugging these values of t back into the original equation for the curve, we can find the point on the curve where the tangent line is parallel to the plane:

x = -2sin(arccos(-a/2))

y = 2cos(arcsin(-b/2))

z = e^(ln(c))

So the point on the curve where the tangent line is parallel to the plane is (-2sin(arccos(-a/2)), 2cos(arcsin(-b/2)), c).

The cost of an adult ticket is $80, and the cost of a child ticket is $50.

Let's denote the cost of an adult ticket as "A" and the cost of a child ticket as "C". We can set up a system of equations based on the given information:

For Family 1: 2A + 3C = 310 (equation 1)

For Family 2: 3A + 4C = 440 (equation 2)

We have two equations with two unknowns (A and C). We can solve this system of equations to find the values of A and C.

We can start by eliminating one variable. Let's multiply equation 1 by 3 and equation 2 by 2:

6A + 9C = 930 (equation 3)

6A + 8C = 880 (equation 4)

Now, subtract equation 4 from equation 3 to eliminate A:

(6A + 9C) - (6A + 8C) = 930 - 880

C = 50

Now, substitute the value of C back into equation 1 to solve for A:

2A + 3(50) = 310

2A + 150 = 310

2A = 310 - 150

2A = 160

A = 80

Therefore, the cost of an adult ticket is $80, and the cost of a child ticket is $50.

In conclusion, the price of an adult ticket is $80, and the price of a child ticket is $50.

The value of i/s is 0.02.

Now, According to the question:

"Information available from the question"

s/a = 4; l/a = 0.20; i/e = 0.10; a = l e and a = 100.

We have to find the i/s

We can first find the value of e, using the equation a = l + e, where l/a = 0.20 and a = 100:

e = a - (l/a) * a = 100 - (0.20 * 100) = 100 - 20 = 80

Next, we can find the value of i using the given information i/e = 0.10:

i = i/e * e = 0.10 * 80 = 8

Finally, we can find the value of i/S using the equation i/S = i / (S/a) * a = 8 / (4 * 100) = 8 / 400 = 0.02.

Step-by-step explanation:

The right triangle has one-half the wing span as a leg.

The hypotenuse is 5.8cm and the other leg is 3cm

If we let the unknown leg of the triangle be x, by the Pythagorean theorem we know the sum of the squares of the two legs must be equal to the square of the hypotenuse .

So

x² + 3² = 5.8²

Correct question is;

A football is kicked up into the air. Its height, H, above the ground, in meters, at t seconds can be modelled by () = 24 − 4.9²

(a) Determine the expression for the instantaneous rate of change in height at time t.

(b) Determine ' (2) What does ' (2) represent?

Answer:

A) '() = 24 − 9.8

B) '(2) = 4.4 m/s

It means that at a distance of 2 m above the ground, the speed of the ball is 4.4 m/s

Step-by-step explanation:

We are given the function to represent the height as;

() = 24 − 4.9²

A) expression for the instantaneous rate of change in height at time t will be gotten by differentiation of the height function. Thus;

'() = 24 − 9.8

B) '(2) = 24 - 9.8(2)

'(2) = 4.4 m/s

This means that at a distance of 2 m above the ground, the speed of the ball is 4.4 m/s

The required volume of the given solid is (√16 - r²) -(-√16 - r²).

The measurement of three-dimensional space is volume. It is frequently expressed quantitatively using SI-derived units, as well as several imperial or US-standard units.

Volume and the notion of length are connected.

Volume, which is measured in cubic units, is the 3-dimensional space occupied by matter or encircled by a surface.

The cubic meter (m3), a derived unit, is the SI unit of volume.

So, the integrand often takes the form z upper z lower, where z stands for the solid's lower and upper borders.

We are treating the sphere as a hemisphere as of right now, with the XY-plane serving as its lower boundary. Consequently, you must multiply by 2.

The solid's volume is (√16 - r²) -(-√16 - r²).

Julia had 120 peas to start .

Answer:

  120 peas

Step-by-step explanation:

Before Julia gave Vlada 15 peas, the ratio of their numbers was 3:2. Afterward, Julia still had 10 more peas. You want to know the number Julia started with.

Let j represent the initial number of peas Julia had. Then Vlada had 2/3j peas. After the transfer, the difference was ...

  (j -15) -(2/3j +15) = 10

  1/3j -30 = 10

  1/3j = 40

  j = 120

Julia had 120 peas at first.

__

Additional comment

The transfer of peas decreases the difference by 30, so if it remains 10 it must have originally been 40. The difference in initial ratio units is 3-2 = 1, so Julia's initial 3 ratio units represent 3·40 = 120 peas.

The value of x is 111°

Arc angle theorem states that If two chords intersect inside a circle, then the measure of each angle is one-half the sum of the measures of the arcs intercepted by the angle and its vertical angle.

Representing the arc angle of x by y

y = 180-137( angle on straight line)

y = 43°

Therefore;

y = 1/2 ( x-25)

43 = 1/2 ( x-25)

Exponential functions are mathematical functions that involve an exponent or power. There are two types of exponential functions: growth and decay.

1. Exponential Growth Functions: These functions have the form y = a*b^x, where a > 0 and b > 1. They model exponential growth, where the value of y increases rapidly as x increases. For example, the function y = 2^x is an exponential growth function, as the value of y doubles for each increase in x.

2. Exponential Decay Functions: These functions have the form y = a*b^x, where a > 0 and 0 < b < 1. They model exponential decay, where the value of y decreases rapidly as x increases. For example, the function y = (1/2)^x is an exponential decay function, as the value of y is halved for each increase in x.

Both types of exponential functions are important in many fields, including finance, biology, and physics. They are used to model phenomena such as compound interest, population growth, and radioactive decay.

Answer:

Step-by-step explanation:

Formula for compound interest:

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

We know that Serena pays annually meaning yearly (12 months or 1 year)

So after substituting all the numbers in,

A= 1000(1+0.02/12)^(12x10)

We change the rate to 0.02 because we must divide 2% by 100%. And divide the rate by number of times applied per time (n).
