but I dont :) goodluck tho

Answer:

D) 21,237.2

Step-by-step explanation:

V= πr^2h

D= 26

r= 13

V= π13^2(40)

V = 169(40)π

V = 6760π

V = 21226.4

Answer:

y = 10.5qt

x = 12 qt

Step-by-step explanation:

0.6x+ 0.36y = 22.5 * 0.2

0.06x + 0.36y = 4.5

x + y = 22.5

x = 22.5 - y

0.06(22.5 - y) + 0.36y = 4.5

1.35 - 0.06y + 0.36y = 4.5

0.3y = 4.5 - 1.35

0.3y = 3.15

y = 3.15 / 0.3

y = 10.5 qt

x = 22.5 - y

x = 22.5 - 10.5

x = 12 qt

Answer:

16

Step-by-step explanation:

(200*2)/25=16

Answer:

6

Step-by-step explanation:

100/4 = 25%

24/4 = 6

Answer:

Step-by-step explanation:

Answer:

x > 25

Step-by-step explanation:

3(2x−8)>4x+26

Step 1: Simplify both sides of the inequality.

6x−24>4x+26

Step 2: Subtract 4x from both sides.

6x−24−4x>4x+26−4x

2x−24>26

Step 3: Add 24 to both sides.

2x−24+24>26+24

2x>50

Step 4: Divide both sides by 2.

2x

x>25

Answer:

Infinately many solutions.

Step-by-step explanation:

2x-4=2(x-2)

Distribute

2x-4=2*x-2*2

2x-4=2x-4

Since both sides are the same, there are infinately many solutions.

Hope this helps!

Answer:

•cos(s+t) = cos(s)cos(t) - sin(s)sin(t) = (-⅖).(-⅗) - (√21 /5).(⅘) = +6/25 - 4√21 /25 = (6-4√21)/25

•cos(s-t) = cos(s)cos(t) + sin(s)sin(t) = (-⅖).(-⅗) + (√21 /5).(⅘) = +6/25 + 4√21 /25 = (6+4√21)/25

cos(t) = ±√(1 - sin²(t)) → -√(1 - sin²(t)) = -√(1 - (⅘)²) = -⅗

sin(s) = ±√(1 - cos²(s)) → +√(1- cos²(s)) = +√(1 - (-⅖)²) = √21 /5

Answer: f

Step-by-step explanation: I chose f because m=29.57 which is is the starting point

Answer:

trapezoid.

Step-by-step explanation:

A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs

Characteristics of a trapezoid

It has 4 vertices and edges

If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram

Area of a trapezoid = [tex]\frac{1}{2}[/tex] x (sum of the lengths of the parallel sides) x height

Perimeter =  sum of lengths of sides of a trapezoid

Answer:

85% - 85/100 - 0.85

Step-by-step explanation:

Answer:

Note that the three identities above all involve squaring and the number 1.You can see the Pythagorean-Theorom relationship clearly if you consider the unit circle, where the angle is t, the "opposite" side is sin(t) = y, the "adjacent" side is cos(t) = x, and the hypotenuse is 1.. We have additional identities related to the functional status of the trig ratios:

Answer:

The Y intercept is two

Step-by-step explanation:

The y intercept is the point on a graph where the graph crosses the y axis.

Basically, it is the value of y when x is 0 is (x,y)

Looking at the attached graph, our y intercept is (0,2), meaning that the y-intercept is 2.

The answer is: the Y-INTERCEPT is 2

Answer:

function is linear and decreasing

Step-by-step explanation:

as shown in the graph between points (4,0) and (6,0)

Answer:

the answer will be the second one or B

Answer:

0.00852 miles per hour

Step-by-step explanation:

Given that:

Distance = 7.5 feets

Time taken = 10 minutes

Speed = distance / time taken

Speed = 7. 5 feets / 10 minutes = 0.75 feets / minutes

Converting to miles per hour :

0.75 feets / minute :

1 mile = 5280 feets

1 minute = 1/60 = 0.0166666 hour

0.75 feets / minute = (0.75/5280)mile / 0.0166666

= 0.0001420 / 0.0166666 mile per hour

= 0.0085200 miles per hour

= 0.00852 miles per hour

Answer:

So Imma use the explanation area to answer this (I'll link a video on how I solved this.)

Step-by-step explanation:

F(x)=1/3(-5x -4)³-3 (Multiply 1/3 by -5x & -4. Be sure to move the unused parts of the equation down)

F(x)= -1.66x -1.33³-3 (Here we need to use our exponent)

F(x)= -1.66x -2.37 -3 (Here we need to subtract -3 from -2.37)

F(x)= -1.66x - 0.629 (You need to subtract 0.629 from the right side and left side)

-0.629 =  -1.66x (Now since X is attached by multiplication, we need to divide both sides by -1.66)

0.378 = x (this means that your inverse is 0.378)

Step-by-step explanation:

Answer:

3

Step-by-step explanation:

To find the rate of change, we want to use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values using two given points. I will use the first and last points.

(1, -2) & (13, 34)

(34 - (-2)) / (13 - 1)

Simplify the parentheses.

= (34 + 2) / (12)

= 36/12

Simplify the fraction.

36/12

= 3

This is your slope.

Hope this helps!

Answer:

5

Step-by-step explanation:

Given the profit equation ;P(x)

x = number of units sold

P(x) = profit made

P(x) = 101

101 = 0.2x^2+20x-4

0.2x^2+20x-4 - 101

0.2x² + 20x - 105 = 0

Using the formula:

-b±[sqrt(b² - 4ac) / 2a]

Where ;

a = 0.2 ; b = 20, c = - 105

Using the quadratic equation solver to save time :

The roots are :

-105 and 5

Items sold cannot be negative ;

Hence, x = units sold = 5
