You just need to substitute the the given function. So if f(-8) then you fill in f(n)=2n+4 which would be f(-8)=2(-8)+4. Which is -12.

hope this helps !

Round each number to the nearest tenth. What is the best estimate for the answer to 471.41 – 397.46? A. 70 B. 73.9 C. 74 D. 74.9

Anuta_ua [19.1K]

First you need to subtract 471.41 and 397.46.

471.41 - 397.46= 73.95

The tenths place is the number after the decimal. In number 73.95, the number in the tenths place would be 9. The answer would be C) 74.

(Let me know if you don't understand. I'll try to explain it in more detail.)

use a numerical method to estimate the value of the limit (if it exists.) Lim e^5t -1 /t as x tends to 0 from both sides

Hello from MrBillDoesMath!

Answer:

Discussion:

Consider the expansion of e^x:

e^x = 1 + x + x^2/2 + x^3/6 +...... => replace x by 5t

e^(5t) = 1 + (5t) + (5t)^2/2 + .... => subtract 1 from both sides

e^(5t) - 1 = (5t) + (5t)^2/2+.... => divide both sides by t

(e^(5t) -1)/ t = 5 + (25/2) t +....

so as t ends to 0 the quotient tends to

5 + (25/2)0 + (other terms) *0 -> 5

Thank you,

MrB

Which statements are true for triangle lnm? check all that apply. the side opposite ∠l is nm. the side opposite ∠n is ml. the hy

balu736 [363]

The statements that are true about ΔLNM are:

Hypotenuse = LN

Opposite side to ∠L = NM

Side opposite to ∠N = ML.

<h3>What is a Right Triangle?</h3>

A right triangle has right angle (angle 90) that is opposite to the longest side (hypotenuse).

From the image given, the right triangle has a right angle at angle M, which is oppposite to the hypotenuse, LN.

Therefore, the true statements about the triangle are:

Hypotenuse = LN
Opposite side to ∠L = NM
Side opposite to ∠N = ML.

Answer:

$\frac{5}{6}$

Step-by-step explanation:

The total number of squares is 36, and only 6 of them are shaded therefore, the remaining 30 are not shaded. The probability that a randomly selected square is not shaded would therefore be:

$\frac{30}{36} = \frac{10}{12} \\ = \frac{5}{6}$
