Mrs. Williams assigned her class a project to find the height of a flagpole. The students could not measure the height, so they used a mirror to determine the height of the flagpole. Jerrica placed a mirror on the ground 20 feet from the base of the flagpole and backed up until the top of the pole was centered in the mirror. Jerrica is 5.6 feet tall and is standing 7.4 feet from the mirror.

What is the height of the flagpole?

The volume of the canister is 36.7 in³. The volume of box is 482.6 cm³

To find the volume of a canister, we can use the formula V = πr²h, where V is the volume, r is the radius, and h is the height.

In this case, the canister has a radius of 1.56 inches and a height of 6.93 inches,

volume of canister = π × (1.56 inches)² × 6.93 inches

volume of canister = 36.7 in³

To find the volume of a box, we can use the formula V = lwh, where V is the volume, l is the length, w is the width, and h is the height.

In this case, the box has a length of 15.5 cm, a width of 8.6 cm, and a height of 3.8 cm

volume of box = 15.5 cm × 8.6 cm × 3.8 cm

volume of box = 482.6 cm³

If the rotation is clockwise the angle is 120°.

If the rotation is counterclockwise the angle is 240°

The correct options are A and D.

We assume that the rotation is clockwise.

First, we can see that the rotation from P to F is just a rotation of 90°.

(point P as at 9 on a clock and point F is at 12 on a clock).

To go from point F to G, we need to move one of the sections defined by the dashed lines, and we know that each one of these measures 30°, then we need to add another 30° to the angle.

90° + 30° = 120°

Then the angle of rotation to map P to G is 120°.

The correct option is D.

In this problem we find a representation of a parabola, which is described algebraically by quadratic equations, that is, polynomials of the form:

y = a · x² + b · x + c

Where a, b, c are the coefficients of the polynomial.

We can determine the value of the coefficients from the knowledge of three points set on Cartesian plane. First, select the points from Cartesian plane:

(x₁, y₁) = (0, 18), (x₂, y₂) = (4, 2), (x₃, y₃) = (7, 11)

Second, create a system of linear equations with three variables and three equations by replacing the variables x and y on the quadratic equation:

c = 18

16 · a + 4 · b + c = 2

49 · a + 7 · b + c = 11

The sum of the arithmetic sequence 1, 3, 5, 7, … , 99 is 2525

Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

Given sequence is 1, 3, 5, 7, … , 99.

It is a arithmetic sequence, the difference between two consecutive terms will be same

d=3-1=2

first term a=1

l=last term =99

We need to find 99 is which term in the sequence

Aₙ = a + ( n - 1 ) d

99=1+(n-1)2

99=1+2n-2

99=2n-1

100=2n

Divide both sides by 2

50=n

Now we need to find the sum of 50 terms

Sₙ=n/2(l+d)

=50/2(99+2)

=25(101)

Answer:

Sydney will have to pay -5, and her brother will have to pay -7. Her brother will have to pay $2 more than Sydney.

Step-by-step explanation:

She invested $1000 at 2% and 2200 at 5% simple interest.

We know simple interest (SI) is given by SI = (p×r×t)/100, where

p = principle, r = rate in percentage, and t = time in years.

Given, P₁ = 1000, P₂ = 2200, assuming r₁ = x% and r₂ = (x + 3)% and the sum of simple interest obtained from both these investments is $130.

∴ (1000×x×1)/100 + {(2200×(x + 3)×1}/100 = 130.

10x + 22x + 66 = 130.

32x = 64.

The given graph shows different values of y at x = 4 and x = 14 as follows,

At x = 4, y = 7

And at x = 14, y = 3.

Now, the average rate of change can be determined by taking the ratio of the difference of the values of y to that of x as follows,

Answer:

133, 412500, 500, 1.184, 37.8, 10, 0.6

Step-by-step explanation:

If we think about how many centimeters are in a meter, we know that

1m = 100cm

Using this, we can see that

20m = 2000cm

Now divide by 15:

2000 ÷ 15 ≈ 133

She can make roughly about 133 ribbons.

To solve the next question, we need to know how many kilometers are in a meter

1km = 0.001m

Let's covert 0.75 into m:

0.75 × 1000 = 750

Now solve for the area:

750 × 550 = 412500

The area of the rectangle is 412500

If he is selling the home for 206,250,000 pesos,

206,250,000 divided by 412500

206,250,000 ÷ 412500 = 500

The price per square meter is 500

If each glass is 148 milliliters, and we need to convert that into liters, we can use the equation:

1L = 1000mL

So converting 148 into liters,

148mL = 0.148L

Now, multiply by 8.

0.148 × 8 = 1.184L

We need to convert 100 Fahrenheit to Celsius.

100 F ≈ 37.8

This is definitely not a normal body temperature.

We can convert grams to kilograms using the equation:

1kg = 1000 g

Converting 2.5kg to g would look like this:

2.5kg = 2500g

250g × 10 = 2500g

We need to buy 10 packs of sugar.

If 120 grams of powdered milk can produce 60 cups of milk, and we need to figure out how many kg can produce the same amount, we use the equation:

1kg = 1000g

Converting 120g to kg would look like this:

120 ÷ 1000 = 0.120

Now, we need to figure out how many times 12 goes into 60.

12 × 5 = 60

Now we multiply 0.120 by 5

0.120 × 5 = 0.6

The total distance covered is 15000 m. The total time taken is 5220 seconds and the speed is 2.87 m/s.

We know that speed has to do with the ratio of the distance that has been covered to the time taken. The speed is a scalar quantity and as such we do not consider the direction hence we would not consider that going back in the opposite direction. The total distance can be obtained algebraically.

The total distance that the student travelled can be obtained from;

5000 m + 5000 m + 5000 m

= 15000 m

The total time taken in seconds = 1800 seconds + 1800 seconds + 1620 seconds

In economics, business, and particularly cost accounting, the break-even point is the point at which total cost and total income are equal, or "even." Although opportunity costs have been paid and capital has obtained the risk-adjusted, projected return, there is no net loss or gain, and one has "broken even."

In the given question, last year sales=  birr 100000

net profit= 8% of sales

Fixed costs= birr 170000

Estimated sales increase= 25%

Estimated net profit= birr 30000

Increase in fixed cost due to moving to low-rent warehouse= birr 30000

(a) The break-even point under the old situation (X):

(b) The break-even point under the proposed situation is:

      = 1,250,000 x b - 170,000- 30,000

      The break-even point under the proposed situation is 806451 and

(c) The birr sales volume must be obtained under the proposed plan to make as much profit as last year is:

For the function y = 4x⁵, the value of d⁴y/dx⁴ = 320x.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. In mathematics, the derivative of a function of a real variable measures the sensitivity to change of the function value with respect to a change in its argument. We can write -

y = f(x)

y' = dy/dx = (d/dx)[f(x)]

We have the following function -

y = 4x⁵

The given function is -

y = 4x⁵

dy/dx = 20x⁴                             {y = xⁿ, then y' = nxⁿ ⁻ ¹}

d²y/dx² = 80x³
