10u+t = 10t+u+18
9u-9t=18
2....u-t=2
Add equation1 & 2
t+u+u-t=16+2
2u=18
u=9
so t= 7
Your answer is = 97

Find the minimum and maximum values for the function with the given domain interval.

AlexFokin [52]

Step-by-step explanation:

e^(x+h) is always larger than e^x.

so the minimum function value in that interval is e⁴.

and the maximum function value in that interval is e⁶.

e⁴ = 54.59815003... ≈ 54.60

e⁶ = 403.4287935... ≈ 403.43

What is the volume of the cone? cone v = one-third b h startfraction 70 over 3 endfraction pi centimeters cubed startfraction 14

Bas_tet [7]

Using the assumed values, the volume of the cone is $V = \frac {250}3\pi$

<h3>How to determine the volume of the cone?</h3>

The volume of a cone is calculated using:

$V = \frac 13\pi r^2h$

The parameters are not given.

So, we use the following assumed values

Radius, r = 5

Height, h =10

Using the assumed values, we have:

$V = \frac 13\pi * 5^2 * 10$

Evaluate the product

$V = \frac {250}3\pi$

Hence, using the assumed values, the volume of the cone is $V = \frac {250}3\pi$

3(-0.4n-0.7)=-3.2n-2.58

svlad2 [7]

Answer:

$n=-0.24$

Step-by-step explanation:

$3\left(-0.4n-0.7\right)=-3.2n-2.58$

Use distributive property.

$-1.2n-2.1=-3.2n-2.58$

$-1.2n-2.1+2.1=-3.2n-2.58+2.1$

$-1.2n=-3.2n-0.48$

$-1.2n+3.2n=-3.2n-0.48+3.2n$

$2n=-0.48$

$\frac{2n}{2}=\frac{-0.48}{2}$

$n=-0.24$
