The answer is -13. Solution: = |-4b - 8| + |-1 - b^2| + 2b^3 = |-4(-2) - 8| + |-1 - -2^2| + 2(-2)^3 = |8-8| + |-1+4| + 2(-8) = |0| + |3| + (-16) = -13

An object oscillates 4 feet from its minimum height to its maximum height. The object is back at the maximum height every 3 seco

bulgar [2K]

Answer:

$y=2\text{cos}((\frac{2\pi}{3})t)$

Step-by-step explanation:

We have been given that an object oscillates 4 feet from its minimum height to its maximum height. The object is back at the maximum height every 3 seconds. We are asked to find the cosine function that can be used to model the height of the object.

We know that standard form of cosine function is $y = A\cdot \text{cos}(Bt-C)+D$ , where,

|A| = Amplitude,

Period = $\frac{2\pi}{|B|}$ ,

C = Phase shift,

D = Vertical shift.

Since distance between maximum and minimum is 4, therefore, amplitude will be half of it, that is, $A = 2$ .

Since objects gets back to its maximum value in every 3 seconds, therefore, period of the function is 3 seconds. We know that period is given by $\frac{2\pi}{|B|}$ , therefore, we can write $\frac{2\pi}{|B|}=3$ , therefore, $B = \frac{2\pi}{3}$ .

We haven't been given any information about phase and mid-line, we can assume the values of C and D to be zero .

Therefore, our function required function would be $y=2\text{cos}((\frac{2\pi}{3})t)$ .

0.75(3.5a-6b) what is the answer when you distribute this expression

nexus9112 [7]

0.75*3.5a = 2.625a

0.75*6b = 4.5b

2.625a - 4.5b is our final answer

What is the value of COS H?<br> Round to four decimal places if needed.

german

Answer:

Final answer is approx $\cos\left(H\right)=0.4235$ .

Step-by-step explanation:

using given information from the attached picture, we need to find the value of cos(H) so let's apply the formula of cosine.

$\cos\left(\theta\right)=\frac{adjacent}{hypotenuse}$

$\cos\left(H\right)=\frac{GH}{FH}$

$\cos\left(H\right)=\frac{36}{85}$

$\cos\left(H\right)=0.423529411765$

Hence final answer is approx $\cos\left(H\right)=0.4235$ .

A rectangular vegetable garden will have a width that is 4 feet less than the length and an area of 140 square feet if x represe

Dennis_Churaev [7]

Answer: x(x-4) = 140 This equation can be solve to find the length.

Step-by-step explanation:

If the width of the rectangle will be 4 less than the length and the length is represented by x then we could have the equation w=x - 4 for the width and the length is just x. And to find the area of a rectangle we multiply the length by the with so multiply x-4 by x for it to equal 140 because 140 is the area.

x(x-4) = 140 solve for x

$x^{2}$ - 4x = 140 subtract 140 from both sides

x^2 - 4x - 140 = 0 find a number that the product is 140 and the sum is -4

-14 and 10 works out.

$x^{2}$ - 14x + 10x - 140 = 0 factor by grouping

x(x -14) 10(x-14) = 0 factor out x-14

(x-14) ( x+10) = 0 set them both equal zero.

x-14= 0 or x+10 = 0

x = 14 or x= -10

Since -10 can't represent a distance, the answer is 14.

Check.

In this case the length is 14 and if the width is 4 less than the length then we will subtract 4 from 14.

14- 4 = 10 so the width is 10.

14 * 10 = 140
