(g-f)(x)=g(x)=f(x)

(g-f)(x)=6x-4+x^2

(g-f)(x)=x^2+6x-4 then:

(g-f)(3)=3^2+6*3-4

(g-f)(3)=9+18-4

(g-f)(x)=23

Answer:

16) No

17) (c)

Step-by-step explanation:

For a lot of multiple-choice matrix problems, a simple test is all that is needed to determine the correct answer.

16) The determinant of A is (-2)(-2) -(2)(-3) = 10. So, we expect to see values in the inverse matrix that are 0.2 and 0.3. Alas, they're not there. The matrices are not inverses.

A^-1 = [[-.2, .3][-.2, -.2]]

17) The matrices are both 3×3, so their product is possible (eliminates choice D). The upper left term is different among the answer choices, so we can determine the correct one by computing that term only.

BA=C

c11 = (5)(1) +(7)(5) +(3)(-1) = 5 +35 -3 = 37

This matches the third choice (C).

If you use a calculator to compute the full matrix product, it matches choice C in all details.

➷ 2) The integral of a constant follows this rule:

adx = ax

In this case, it is 1dx = 1x

This can be simplified to just x

Add a constant to this, to get the final answer of:

x + C

3) The integrals power rule is:

$x^adx = \frac{x^a^+^1}{a +1}$

Substitute the values in:

$\frac{x^5^+^1}{5 +1}$

This can be simplified to:

$\frac{x^{6} }{6}$

Add a constant to this to get the final answer of:

$\frac{x^{6} }{6} +C$

On Monday, Jullo ran 39 miles. On Tuesday, he ran another

Artist 52 [7]

<h3>Answer:</h3>

67 miles

<h3>Step-by-step explanation:</h3>

On Monday, Jullo ran <u>39 miles.</u>

⇒ Monday = 39 miles

On Tuesday, he ran <u>24 miles.</u>

⇒ Tuesday = 24 miles

On Wednesday, he ran <u>4 miles.</u>

⇒ Wednesday = 4 miles

<u>Finding the total miles:</u>

Total miles ran on Monday, Tuesday, and Wednesday = 39 + 24 + 4

= 67 miles
