The answer is A. 11 x 17 - 11x because you would use the <u>distributive property</u> and multiply the number on the outside (11) by everything on the inside (17 and -x)

For this, they are asking you to multiply both 17 and -x by 11. B and C only multiply one term by 11, and D doesn't multiply at all. A is the only one that fits!

Question 2: Please help I do not understand this question.

The measurement of AB is 16.23.

Solution:

Given ACB is a right angled triangle.

AC = 10, ∠C = 90° and ∠A = 52°.

cos θ ≈ 0.616

Here AC is the base and AB is Hypotenuse.

To find the length of AB:

$$\cos\theta=\frac{\text{Base}}{\text{Hypotenuse}}$

$$\cos 52^\circ=\frac{10}{AB}$

$$0.616=\frac{10}{AB}$

Do cross multiplication, we get

$$AB=\frac{10}{0.616}$

AB = 16.23

Hence the measurement of AB is 16.23.

A quadratic function and an exponential function are graphed below. Which graph most likely represents the quadratic function? (

Anton [14]

Answer:

I have no Idea where this question is trying to go because a quadratic function IS an exponential function. The exponent is 2.

Step-by-step explanation:

If the exponent on the exponential function is greater than 2, it will increase faster in the first quadrant than a quadratic equation.

If the exponent on the exponential function is less than 2, the quadratic equation will increase faster in the first quadrant

$\bf \begin{array}{ccllll}
amount&\%\\

\end{array}\implies \cfrac{75}{x}=\cfrac{100}{9\frac{2}{5}}\implies \cfrac{75}{x}=\cfrac{100}{\frac{9\cdot 5+2}{5}}$

$\bf \cfrac{75}{x}=\cfrac{\frac{100}{1}}{\frac{47}{5}}\implies \cfrac{75}{x}=\cfrac{100}{1}\cdot \cfrac{5}{47}\implies \cfrac{75}{x}=\cfrac{500}{47}\implies 75\cdot 47=500\cdot x
\\\\\\
\cfrac{3525}{500}=x\implies \cfrac{141}{20}=x\implies 7.05=x$
