<h3>Answer: 3^7</h3>

This is equivalent to 2187 if you were to evaluate 3^7 with a calculator.

============================================================

Explanation:

The rule you use is

$a^b*a^c = a^{b+c}$

When we multiply exponential expressions with the same base, we add the exponents. The base stays the same.

So,

$3^2*3^5 = 3^{2+5} = 3^7$

If the bases were different, then you cannot use this rule.

Answer:

Ok!

Step-by-step explanation:

So I’m guessing 3^2 means 3x3 basically! If I’m wrong pls correct! Anyways, so you wanna write the equation like so: (3^2) + (3^5). Next, do 3^2 which gets you 9. Then, do 3^5 which gets you 243. I know, it’s confusing haha. Now, add those two together & u get 252! There ya go, hoped it helped (:

Find the height of a trapezoid if the bases have lengths of 6 and 17 and the area of the trapezoid is 46 square units.

Aleksandr [31]

Answer:

4 units

Step-by-step explanation:

The area (A) of a trapezoid is calculated using the formula

A = $\frac{1}{2}$ h(a + b)

where h is the height and a, b the bases

here A = 46, a = 6 and b = 17, hence

46 = $\frac{1}{2}$ h(6 + 17) ( multiply both sides by 2 )

92 = h(23) ← divide both sides by 23 )

h = $\frac{92}{23}$ = 4 units

Solve y=-3x² + 4.5x – 20<br> Use the Quadratic formula

statuscvo [17]

Answer:

$x=0.75 \pm 2.47067i$

Step-by-step explanation:

Quadratic Formula: $x=\frac{-b \pm \sqrt{b^2-4ac} }{2a}$

√-1 is imaginary number i

Step 1: Define

y = -3x² + 4.5x - 20

a = -3

b = 4.5

c = -20

Step 2: Substitute and Evaluate

$x=\frac{-4.5 \pm \sqrt{4.5^2-4(-3)(-20)} }{2(-3)}$

$x=\frac{-4.5 \pm \sqrt{20.25-240} }{-6}$

$x=\frac{-4.5 \pm \sqrt{-219.75} }{-6}$

$x=\frac{-4.5 \pm \sqrt{219.75}(\sqrt{-1} ) }{-6}$

$x=\frac{-4.5 \pm i\sqrt{219.75} }{-6}$

$x=\frac{4.5 \pm i14.824 }{6}$

$x=0.75 \pm 2.47067i$

Find the marginal profit of C(x)=5x^2, R(x)=x^3+7x+10 and find all values of x for which the marginal profit is zero.

jonny [76]

Marginal profit, P(x) = R(x) - C(x)

P(x) = x³ - 5x² + 7x + 10

x³ - 5x² + 7x + 10 = 0
If you solve it, you get x = -0.839 where P(x) is zero
