The value would be A.1

<span>Example:

In mathematics, a square root of a number a is a number y such that y2 = a, in other words, a number y whose square (the result of multiplying the number by itself, or y × y) is a. For example, 4 and −4 are square roots of 16 because 42 = (−4)2 = 16.</span>

Find the discount.
OLEGan [10]
As the amount is $100 dollars, you will have to find what 35% of this is. The best way to do this is to divide both 100 and 35 by ten, giving you ten and 3.5. AS 10 is 10% of 100, you should then multiply then, by three and half, therefore, giving you 35- meaning the discount is $35 dollars. Hope this helps

A window seat is in the shape of a trapezoid. Write the polynomial that represents the area of the window seat.
nadezda [96]

The polynomial that represents the area of the trapezoid shaped window is: 1/2(8x² - 14x - 15).

<h3>What is the Area of a Trapezoid?</h3>

Area of trapezoid = 1/2(a + b)h, where a and b are length of the parallel sides, and h is the height.

Given:

a = 3x + 5

b = x - 2

h = 2x - 5

Thus:

Area of trapezoid = 1/2(3x + 5 + x - 2)(2x - 5)

Area of trapezoid = 1/2(4x + 3)(2x - 5)

Area of trapezoid = 1/2(8x² - 14x - 15)

Therefore, the polynomial that represents the area of the trapezoid shaped window is: 1/2(8x² - 14x - 15).

4. The graph of h(x) = x^2 was transformed to create the graph of k(x) = -4x^2? Which of these describes the transformation from
Viefleur [7K]

Answer:

A. A reflection over the x-axis and a vertical stretch.

Step-by-step explanation:

Let h(x) = x^{2}, to obtain k(x) = -4\cdot x^{2}, we need to use the following two operations:

(i) Vertical stretch

g(x) = k\cdot f(x), k\in \mathbb{R}^{+}

(ii) Reflection over the x-axis

g(x) = -f(x)

Let prove both transformations in h(x):

Step 1 - Vertical stretch (k = 4)

h'(x) = 4\cdot x^{2}

Step 2 - Reflection over the x-axis

k(x) = -4\cdot x^{2}

Hence, correct answer is A.

What are the values of the trigonometric ratios for this triangle?
Zigmanuir [339]

Answer:

sin© = 3/5

Cos© = 4/5

Tan© = 3/4

Explanation:

The opposite (opp) side of the right angle triangle is the side facing the angle ©

The hypothenus (hyp) side is the longest side,

The adjacent (adj) side is the third side.

sin© = opp/hyp

Cos© = adj/hyp

Tan© = opp/adj
