Answer:

x=18.5

u gotta do 3x+2=x+49

combine the like terms and it becomes 2x=37 then divide by 2 u get 18.5

plug it in as x and check if it's right

Answer:

\((g\cdot f) = -3x^2-3\)

Step-by-step explanation:

\(f(x) = x^2 + 1\)

\(g(x) = -3\)

The problem state to multiply the function \(f\) and \(g\) so the symbol seems to be incorrect.

We actually want to calculate

\(g(x) f(x) =gf(x) = (-3) \cdot (x^2+1)= -3x^2-3\)

Note

\(g\circ f(x)=g(f(x))=g(x^2+1)=-3\)

The angle at which the ball takes off, distance the ball in the air, the ball's speed is mathematically given as

Generally, the equation for the verticle component   is mathematically given as

\(y=xtan\theta-\frac{16x^2}{v0cos^2\theta}\\\\Therefore\\\\\theta=tan^{-1}(1.8)\)

theta=60

b)

hmax=vo^2sin^2\theta/2g

vo=116.486

Therefore, distance the ball in the air

\(d=\frac{2*114.486*0.874*2}{32}\)

d=6.3658

c)

The ball's speed when it hits the ground will be vo

vo=116.486

Answer:

Equation of the line  that passes through the midpoint and is perpendicular to PQ is   2 x - y +1 = 0

Step-by-step explanation:

Step(i):-

Given points are P( -4 ,3 ) and Q ( 4,-1)

Mid -point of PQ

                     =      \((\frac{x_{1} + x_{2} }{2} , \frac{y_{1} + y_{2} }{2} )\)

                    =       \((\frac{-4+4}{2} , \frac{3-1}{2} ) = ( 0 , 1 )\)

Step(ii):-

Slope of PQ

             \(m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{-1-3}{4+4} = \frac{-4}{8} = \frac{-1}{2}\)

The slope of the line is Perpendicular to PQ

           \(m_{2} = \frac{-1}{m_{1} } = \frac{-1}{\frac{-1}{2} } = 2\)

Equation of the line  that passes through the midpoint and is perpendicular to PQ

      \(y - y_{1} = m ( x - x_{1} )\)

          \(y - 1 = 2 ( x - 0 )\)

         2 x - y +1 = 0

Final answer:-

Equation of the line  that passes through the midpoint and is perpendicular to PQ

 2 x - y +1 = 0

B. 10x -40

Step-by-step explanation:

To rewrite the expression 5(2x-8) using the distributive property, we need to separate the expression inside the parentheses and then multiply the two expressions by 5. The answer is: 10x-40.

The best estimate for the number of fish is that there are 82 yellow fish and 18 green fish, which you can calculate using the rule of three. This estimate is expected to be accurate.

This can be calculated using a rule of three as follows. Let's start with the yellow fish:

53 = 65

x    = 100

53 x 100 / 65 = 82 yellow fish

Green fish:

12 = 65

x = 100

12 x 100 / 65= 18 green fish

This estimate is expected to be accurate; however, there might be small differences in real life such as 80 yellow fish and 20 green fish.

a) Over the intervals (−∞,−9),(-6,-2) and (3,7) the function is increasing.

b) At x-values x=-6 and x=3 the function have local minima.

c) The sign of the function's leading coefficient is negative.

d) The possibility for the degree of the function is 5 or 7.

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

A function is said to increasing if the value of y increases as the value of x increases.

From the graph, the function is increasing on (−∞,−9),(-6,-2) and (3,7)

The local minima is a point where the function has minimum value in its local neighbour.

From the graph, the function has a local minima at x=-6 and at x=3.

In the end, the value of f(x) decreases as the value of x increases therefore the sign of the function's leading coefficient is negative.

The graph intersects the x-axis 2 times and also the function have 5 turning points both the these information indicates that the function is of 5 degrees or 7 degrees.

Therefore, interval, local minima, coefficient value and degree of function is obtained.

Answer:

a) 388.03

b) 148.49

c) π/8

Step-by-step explanation:

Find the diagram attached

Let the opposite side be y

Given

a) Hypotenuse = 420

theta = 3π/8 rad

theta = 3(180)/8

theta = 67.5degrees

Using the SOH CAH TOA identity

sin theta = opposite/hypotenuse

sin 67.5 = y/420

x = 420sin67.5

x = 420(0.9238)

x = 388.03

Hence the length of the side opposite to the given angle is 388.03

b) Hypotenuse = 420

theta = 3π/8 rad

theta = 3(180)/8

theta = 67.5degrees

Using the SOH CAH TOA identity

cos theta = adjacent/hypotenuse

cos 67.5 = x/420

x = 420cos67.5

x = 420(0.3827)

x = 148.49

Hence the length of the side adjacent to the given angle is 148.49

c) The sum of angle in the triangle is π

Let the measure of the unknown angle be z

z + 3π/8 + π/2 = π

z + 3π+4π/8 = π

z + 7π/8 = π

z = π - 7π/8

z = (8π-7π)/8

z = π/8

Hence the measure of the other acute angle is π/8

Answer:

\(g'(y)=3y^2-4y-8\)

Step-by-step explanation:

start by foiling out the given function

\(g(y)=(y-4)(2y+y^2)\\=2y^2+y^3-8y-4y^2\\=y^3-2y^2-8y\)

next, use the power rule to find the derivative

power rule: To use the power rule, multiply the variable's exponent n, by its coefficient a, then subtract 1 from the exponent. If there's no coefficient (the coefficient is 1), then the exponent will become the new coefficient.

\(g'(y)=3y^2-4y-8\)

Answer:

Step-by-step explanation:

We know that the sum of all the angles in a triangle is 180.

Simplifying gives us m<3 = 80

Answer:

Answer:

7:43 am.

Step-by-step explanation:

it was  1/2 full one minute ago then another 1/2 = 1/4 full 2 minutes ago.

Knowing how the bus fills, we want to find the time where the bus is one-quarter full.

The bus is one-quarter full at 7:43 am.

We know that at 7:45 am the bus is full. Let's say that the full bus has N people inside.

Each minute the population doubles, so if we go backwards, each minute the population is divided by 2.

One minute before, the bus must have half of the above population, meaning that at 7:44 am, the bus has N/2 people.

Another minuter before the people inside is halved again, then at 7:43 am we will have (N/2)/2 = N/4 people.

And if N is the people in a full bus, then N/4 represents the buss a quarter full.

Then we can answer the question as:

The bus is one-quarter full at 7:43 am.

Answer:

Step-by-step explanation:

slope intercept: y = mx + b

where m is the slope and b is the y-intercept

Equation: y = -3x + 4

Since y-intercept is given, then we have the first point of the line as (0,4)

Let's find the value of x when y is 0

y = -3x + 4

0 = -3x + 4

3x = 4

x = 4/3
