A) 19 m
C) 8 m
B) 17 m
D) 12 m

2*(1/3)^2 - 4(1/3) + 3 = 17/9

The area of both the top face and the bottom face of the cuboid is 63 square centimeters (cm²).

To find the area of each face of the cuboid, we'll use the formulas for finding the area of a rectangle (which is the shape of each face of the cuboid).

Given dimensions:

Length (L) = 9 cm

Width (W) = 7 cm

Height (H) = 4 cm

a) Area of the top face of the cuboid:

The top face is a rectangle with dimensions 9 cm (length) and 7 cm (width).

Area = Length × Width

Area = 9 cm × 7 cm

Area = 63 square centimeters (cm²)

b) Area of the bottom face of the cuboid:

The bottom face is also a rectangle with dimensions 9 cm (length) and 7 cm (width).

Area = Length × Width

Area = 9 cm × 7 cm

Area = 63 square centimeters (cm²)

Therefore, the area of both the top face and the bottom face of the cuboid is 63 square centimeters (cm²).

Answer:

5:45pm

Step-by-step explanation:

If Rozene started working at 1pm, we can count the whole numbers in this problem. (in this case, 4) If we count from 1pm, it will land on 5pm. After this part, we know that 1/2 an hour is 30mins, because 1 hour is 60 mins and half of 60 is 30. (60/2=30)

5pm + 30mins = 5:30pm

1/4 hour is a quarter amount of time. If we split the clock into 4 parts, each part is a quarter. (aka 1/4) So 5:30 + 25mins = 5:45pm.

Step-by-step explanation:

a = k/m    or       ma = k    

using 4 and 9     4* 9 = k = 36

then the equation becomes:

    ma = 36    

  using a = 6

      6 * m = 36     shows m = 6 kg

The value of cos(2α + β) using trigonometric identities is; -1.0155

We are given;

α = sin⁻¹(4/5)

β = tan⁻¹(12/5)

Thus;

sin α = 4/5

tan β = 12/5

From trigonometric ratios, we can say that;

cos α = 3/5

sin β = 12/13

cos β = 5/13

We know from trigonometric identities that  cos (a + b) = cos a cos b - sin a sin b.

Thus;

cos(2α + β) = cos 2α cos β - sin 2α sin β

Thus;

cos(2α + β) = 2(3/5) * (5/13)) - ((2 * 4/5 * 12/13))

= 0.4615 - 1.477

= -1.0155

Answer:

5:1

Step-by-step explanation:

20:4 is the same thing is 10:2, because what you do to one side you must do to the other, so I divided each side by 2. Then I do it again to get 5:1 which is the unit rate therefore simplest form. To check my work I can do 4x5 = 20.

Using implicit differentiation dy/dx = -(2x + y)/(x + 2y) and d2y/dx² = -2(x² - 3xy - y²)/(x + 2y)³.

Implicit differentiation is the process of differentiating an equation in which it is not easy or possible to express y explicitly in terms of x.

Given the equation x² + xy + y² = 5,

we can differentiate both sides with respect to x using the chain rule as follows:

2x + (x(dy/dx) + y) + 2y(dy/dx) = 0

Simplifying this equation yields:

(x + 2y)dy/dx = -(2x + y)

Hence, dy/dx = -(2x + y)/(x + 2y)

Next, we need to find d^2y/dx^2 by differentiating the expression for dy/dx obtained above with respect to x, using the quotient rule.

That is:

d/dx(dy/dx) = d/dx[-(2x + y)/(x + 2y)](x + 2y)d^2y/dx² - (2x + y)(d/dx(x + 2y))

= -(2x + y)(d/dx(x + 2y)) + (x + 2y)(d/dx(2x + y))

Simplifying this equation yields:

d2y/dx² = -2(x² - 3xy - y²)/(x + 2y)³

Answer:

12

Step-by-step explanation:

Triangle PQR and triangle STR are congruent and that makes |PR| and |SR| equal in measure:

2x + 6 = 4x export like terms to same side

6 = 4x - 2x subtract

6 = 2x divide both sides by 2

3 = x

SR is represented with 4x now replace x with 3

SR = 4*3 = 12

Answer:

The value of x is 104

Step-by-step explanation:

we are given 52 we know that 52 is within an isosceles triangle.

which means 2 sides are the same which tells us that the two angles touching the unique side will have the same measure

we also know that a triangle adds up to 180 so 52 + 52 gives us 104 meaning the last angle will be 180 - 104 which is 76

now we have completed the first triangle if

if we look at corner c we know that it's a right angle

we know that right angles are a total of 90 degrees we know that the right angle is split into two complementary angles one of them is 52 which we figured from the first part so

90 - 52 would give us 38 now we know that in triangle CDE one of the measures is 38 at the c corner and another is 90 at the E corner

once again we do 90 + 38 = 128 and subtract that from 180 giving us 52.

Now we know the measures of triangle ADC and CDE

We also know that triangle EDB is a congruent mirror reflection of CDE

So by now we have the measures of 3 triangles CDE ADC AND EDB

we also know that angle F/x is equvilant to the total of both of angle D

so we just add 52 + 52 giving us the measure of the whole angle d combined which we know is eqivilant to angle f

So after all that we know that the value of x is 104 degrees.

Step-by-step explanation:

1.

Since you earn 1.25 points every 1-8 minutes, it would take you 4000 (1-8 minutes) in order for you to get 5000 points.

I'll be looking for the range, so we'll find how long it would take for one minute, then eight minutes.

4000 x 1 = 4000 minutes (2 days, 18 hours and 40 minutes)

4000 x 8 = 32000 minutes (22 days, 5 hours and 20 minutes)

It will take anywhere from 2 days, 18 hours and 40 minutes to 22 days, 5 hours and 20 minutes.

2.

Since you earn 3 points every 1-8 minutes, it would take you 1666.666... (1-8 minutes), which would be 1667 since you don't earn points every third of a second, it's only every second, in order for you to get 5000 points.

Same thing, we'll find it for one minute and then eight minutes.

1667 x 1 = 1667 minutes (1 day, 3 hours and 47 minutes)

1667 x 8 = 13336 minutes (9 days, 6 hours and 16 minutes)

It will take you anywhere from 1 day, 3 hours and 47 minutes to 9 days, 6 hours and 16 minutes.

10 Bunches

Step-by-step explanation:

4 bunches= 8$

/8 for how many bunches per 1$

.5bunches= 1$

*20

10bunches=20$

Given statement solution is :- The present value of R13,000 per year invested for 8 years at 10% compound interest is approximately R69,776.60.

To calculate the present value of an investment with compound interest, we can use the formula for the present value of an annuity:

PV = A *\((1 - (1 + r)^(-n)) / r\)

Where:

PV = Present value

A = Annual payment or cash flow

r = Interest rate per period

n = Number of periods

In this case, the annual payment (A) is R13,000, the interest rate (r) is 10% per year, and the investment is made for 8 years (n).

Using the formula and substituting the given values, we can calculate the present value:

PV = \(13000 * (1 - (1 + 0.10)^(-8)) / 0.10\)

Calculating this expression:

PV = \(13000 * (1 - 1.10^(-8)) / 0.10\)

= 13000 * (1 - 0.46318) / 0.10

= 13000 * 0.53682 / 0.10

= 6977.66 / 0.10

= 69776.6

Therefore, the present value of R13,000 per year invested for 8 years at 10% compound interest is approximately R69,776.60.

Answer:

The measure of angle N is 58 degrees (58°).

Step-by-step explanation:

If angle M is a right angle, it means it measures 90 degrees (90°) since a right angle is always 90 degrees.

In a triangle, the sum of the angles is always 180 degrees (180°). So, we can find the measure of angle N by subtracting the measures of angles L and M from 180 degrees.

Angle L is given as 32 degrees (32°) and angle M is 90 degrees (90°).

Angle N = 180° - angle L - angle M

Angle N = 180° - 32° - 90°

Angle N = 58°

Therefore, the measure of angle N is 58 degrees (58°).

Answer:n= 58 degrees

Step-by-step explanation:

so all u do is 90 “right angle” minus 32 which is 58! Hope this helped!

The mistake that Rafael made is interchanging the y-values with the x-values.

The real slope of the line is 25.

In Mathematics, the slope of any straight line can be determined by using this mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = rise/run

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Substituting the given data points into the slope formula, we have the following;

Slope (m) = (100 - 50)/(4 - 2)

Slope, m = 50/2

Slope, m = 25.
