Answer:

Answers: 1) gh= -7×3= -21

2) g2-h= -7×2-3= -17 *that is what I got from my calculations.

3) g+ h2 = -7+3×2= 1 *that is what I got from my calculations.

4) g+h = -7+3 = -4

5) h-g= 3--7= 3+7= 10

6) g-h= -7-3= 10

Step-by-step explanation:

I don't fully understand neither but I tried.

If two pounds of meat will serve 5 people how many pounds will be needed to serve 13 people

miv72 [106K]

The answer is 5.2 pounds of meat. To find this just divide the number of people by what the information you have about servings. 13/5=2.6(number of sets), then you multiply that by how many pounds are in each set. 2.6 sets* 2 pounds per set= 5.2 pounds.
I hope this helped!

Analyze a graph In Exercise,analyze and sketch the graph of the function.Label any relative extrema, points of inflation,and asy

ZanzabumX [31]

Answer:

Step-by-step explanation:

Given is a function f(x)

$f(x) = e^x -e^{-\frac{{x}}{2}$

We have to analyse and sketch the graph

X intercept : Put y =0, we get x=0

Y intercept: Put x =0 , we get y =0

No exception for x or y and hence set of all real numbers is domain and range.

$f'(x) = (e^x +1/2 e^{-\frac{{x}}{2})$

f' becomes 0 not at finite points

So relative extreme

Graph is sketched and attached

Eleanor scores 680 on the mathematics part of the SAT. The distribution of SAT math scores in recent years has been Normal with

Katen [24]

Answer:

Elanor's standardized score is 1.19
Gerald's standardized score is 0.72
Elanor has higher score

Step-by-step explanation:

To compare Elanor's and Gerald's math scores, we need to standardize them and calculate their z-scores.

z score can be calculated using the formula

z= $\frac{X-M}{s}$ where

X is the student's score

M is the mean score of the exam

s is the standard deviation of the exam

Elanor's standardized score is:

z(e) = $\frac{680-554}{106}$ ≈ 1.19

Gerald's standardized score is:

z(g)= $\frac{27-24.7}{3.2}$ ≈ 0.72

Since z(e) > z(g), Elanor has higher score

If a convex polyhedron has 12 edges and 8 faces, then how many vertices does it have?

Vika [28.1K]

Hi

Use Euler's formula for this for a 3D figure. F + V = E + 2, where F is the number of faces, V is the number of vertices, E is the number of edges, +2! You have enough info to fill in the formula to find that the number of vertices is 6.
