step-by-step explanation:

you need a graphing calculator.

so, let's start by setting up a table (for my sake because that text is confusing)

x       f(x)      g(x)      h(x)

-3      12        39          -14

0       0         3           1

1        0         7           -2

okay, that's out of the way. now, your equation is 2 * f(3) - 3 * g(1) + h(3).

for f(3), we look at the chart to see which f(x) value matches x=3.

f(3) = 6

same with g(1) and h(3)

g(1) = 7

h(3) = -20

now, replacing the functions(x) with their numbers is the next step.

2 * 6 - 3 *7 + (-20)

(2*6) - (3*7) - 20

What is stratified sampling ?

Stratified sampling is a sampling technique which used when we do a research on a heterogenous population. How to use this technique is to divide the population into several stratum and then take random samples from each stratum an then all the samples that have been taken are collected into one sample.

Answer:

[tex] \huge{ \boxed{gof(3) = 9}}[/tex]

Step-by-step explanation:

In order to find gof(3), we first have to find gof(x). To find gof(x) substitute the f(x) into g(x). That is, for every x found in g(x) substitute it by f(x).

From the question

[tex]f(x) = 2 {x}^{2} - x - 15 \\ g(x) = - 5x + 9 \\ \\ gof(x) = - 5(2 {x}^{2} - x - 15) + 9 \\ gof(x) = - {10x}^{2} + 5x + 75 + 9 \\ \\ gof(x) = - {10x}^{2} + 5x + 84[/tex]

To find gof(3), substitute the value of x that is 3 into gof(x). For every x found in gof(x), replace it by 3 and solve.

[tex]gof(3) = - 10( {3})^{2} + 5(3) + 84 \\ \quad \: \: \: \: \: = - 10(9) + 15 + 84 \\ \: \: \: = - 90 + 15 + 84 \\ = 9[/tex]

C and E are the solutions to this system.

The unit price of the oranges bought by the three friends is $3.50 per pound.

Lamar bought 2 pounds for $7 , unit price = 7 / 2 = $ 3.5 per pound

Enrico bought 5 pounds for $17.50 , unit price = 17.50 / 5 = $ 3.5 per pound

Anna bought 3 pounds for $10.50 , unit price = 10.5/ 2 = $3.5 per pound

Hence we can see that the unit price rate for the oranges is $3.50 .

The average price of a product is calculated by dividing the total sales income by the number of units sold. Managers must supply "similar" units when a single product is given in many variations, such as different bottle sizes.

By weighting different unit selling prices higher by unit sales mix (%) for each single variant, the determination of average pricing is made practicable. We obtain pricing per statistical unit when we employ a standard rather than a genuine range of sizes and product types.

Answer:

The sum of the angles is 180°.

We already know that one angle is 90°, and the other one is 38.

so: 180-(90+38)=52°

the exterior angle+52°= 180° (beacuse the form a flat angle)

so x=180-52

so: x=128°.

Answer:

128°

Step-by-step explanation:

We know that,

   the exterior angle of a triangle is equal to the sum of the interior opposite angles of a triangle.

Accordingly,

38 + 90 = x

128° = x

Answer: Location of T' on the coordinate axis will be (16,7).

T (6,4) → T' (16,7).

Step-by-step explanation:

coordinate vertices of points in rectangle JKLM are:

J (-8,-8)

K (-4,-8)

L (-4,-5)

M (-8,-5)

and coordinate vertices of points in rectangle J'K'L'M' are:

J' (2,-5)

K' (6,-5)

L' (6,-2)

M' (2,-2)

coordinate vertices of points in Quadrilateral STUV are:

S (1,4)

T (6,4)

U (4,6)

V (2,6)

transformation in coordinate vertices from rectangle JKLM to rectangle J'K'L'M' is:

J (-8,-8) → J' (2,-5)

⇒ along x axis -8 → 2 which means that rectangle is shifting towards right by 10 units.

and along y axis -8 → -5 which means that the rectangle is shifting upwards by 3 units.

similarly for

K (-4,-8) → K' (6,-5)

⇒ along x axis -4 → 6 which means that rectangle is shifting towards right by 10 units.

and along y axis -8 → -5 which means that the rectangle is shifting upwards by 3 units.

L (-4,-5) → L' (6,-2)

⇒ along x axis -4 → 6 which means that rectangle is shifting towards right by 10 units.

and along y axis -5 → -2 which means that the rectangle is shifting upwards by 3 units.

M (-8,-5) → M' (2,-2)

⇒ along x axis -8 → 2 which means that rectangle is shifting towards right by 10 units.

and along y axis -5 → -2 which means that the rectangle is shifting upwards by 3 units.

So, the location of T' of the Quadrilateral S'T'U'V' on the coordinate plane will be:

along x axis the Quadrilateral will shift towards right by 10 units

So, 6 → 6+10=16

and along y axis the Quadrilateral will shift upwards by 3 units

So, 4 → 4+3=7

⇒ T (6,4) → T' (16,7).

Answer: B 10.6

Explanation:

We would assume that the stock tank is cylindrical. We would calculate the volume by applying the formula,

Volume = πr^h

where

π = 3.14

r is the radius of the cylinder

h is the height of the cylinder

From the information given,

diameter = 3

radius = diameter/2 = 3/2

r = 1.5

h = 1.5

Volume = 3.14 x 1.5^2 x 1.5 = 10.5975 cubic meters

By rounding to the nearest tenth,

Volume = 10.6 cubic meters

Step-by-step explanation:calculator

Answer:

82x82x82x82, or 82 squared to the 4th power, is 45212176.

EXPLANATION

If the measure of ∠2= x+78 and the other ∠=40 degrees, by definition we know that sum of interior angles of a triangle is equal to 180 degrees.

Furthermore, we have two congruent legs, so this is an Isosceles triangle with two congruent angles (with the same measure).

Thus,

180 = 40 + 2* m∠2

Substituting m∠2 by the equation as follows:

180 = 40 + 2(x + 78)

Subtracting -40 to both sides:

180 - 40 = 2(x+78)

Simplifying:

140 = 2(x+78)

Dividing both sides by 2:

140/2 = x + 78

Simplifying:

70 = x + 78

Subtracting -78 to both sides:

70 - 78 = x

Simplifying:

-8 = x

Switching:

x = -8

Answer: The value of x is -8.
