Hello from MrBillDoesMath!

Answer:

Discussion:

Total Surface area = area of pyramid base + 4 ( area of triangular face)

In our case this becomes

4*4 + 4( (1/2) (4)(7) ) =

= 16 + (2)(4)(7)

= 16 + 56

= 72

which is the first choice.

Note: the area of a triangular face was computed using (1/2) b h, which in our case is

(1/2) (4) (7)

Thank you,

MrB

Determine whether each function is linear or quadratic. Identify the quadratic, linear, and constant terms. g(x)=-2 x²-3(x-2)

valentinak56 [21]

The function g(x) is a quadratic function:

Its quadratic term is -2x²
Its linear term is - 3x
Its constant is 6

<h3>What are functions?</h3>

Functions are algebraic expressions that have at least two variables, in order to make their visual representation through a graph and evaluate their behavior.

This problem deals with linear or quadratic functions, and these differ in the degree of the exponent of the variable:

1 : linear

2 : quadratic

The function:

g(x) = -2x² - 3(x- 2).

g(x) = -2x² - 3x + 6 , we have a quadratic function.

Its quadratic term is -2x²
Its linear term is - 3x
Its constant is 6

a strip of paper is 9/10 of an inch long. you need to cut the paper into 3/12 inch pieces. how many pieces will you be able to c

e-lub [12.9K]

We have to divide 9/10 by 3/12.

if we divide by a fraction, we can instead multiply by it's inverse:

$\frac{9}{12}/ \frac{3}{12} = \frac{9}{12} * \frac{12}{3}$

so now we count:

$\frac{9}{12} * \frac{12}{3} =\frac{9}{1} * \frac{1}{3}=3$

so we can cut exactly 3 pieces!

In an effort to determine the most effective way to teach safety principles to a group of employees, four different methods were

musickatia [10]

Answer:

critical value = 5.29

Step-by-step explanation:

Given that they are divided into 4 groups and a sample of 5 test was selected

N = 5 * 4 = 20

k = 4

∝ = 0.01

Df for numerator ( SS group )= k - 1 = 3

Df for denominator ( SSE group ) = N - k = 20 - 4 = 16

DF ( degree of freedom )

Next we will use the F table to determine the critical value

Critical value = $F_{16,3,0.01}$ = 5.29
