Answer 1

Answer :

$38 + $2(n) where n is the no. of cars.

Step-by-step explanation:

He earns $38 daily which is fixed and additional $2 wage depends on the no. of cars which means no. of cars will determine how many $2's he earns.

25 cars = $38 + $2 (25) = $88

30 cars = $38 + $2 (30) = $98

35 cars = $38 + $2 (35) = $108

40 cars = $38 + $2 (40) = $118

find f(-5)

Answers

Answer:

f(- 5) = 25

Step-by-step explanation:

To evaluate f(- 5) , substitute x = - 5 into f(x) , that is

f(- 5) = - (- 5)² - 10(- 5) = - 25 + 50 = 25

A pizza pan is removed at 9:00 PM from an oven whose temperature is fixed at 425°F in a room that is constant 74°F. After 5 minutes, the pizza pan is at 300 °F

A) at what time is the temperature of the pan 130°F ?

B) determine the time that needs to elapse before the pan is 180°

Answers

Answer:

9:11:48 p.m

9.8 minutes

Step-by-step explanation:

We Obtian the slope of the relation :

Slope = Rise / Run

(0, 425) ; (5, 300)

x2 = 0 ; y2 = 425 ; x1 = 5 ; y1 = 300

(425 - 300) / (0 - 5)

125 / - 5

= - 25

The intercept :

y = mx + c

425 = - 25(0) + c

425 = 0 + c

c = 425

The equation becomes :

y = - 25x + 425

Temperature at 130

130 = - 25x + 425

130 - 425 = - 25x

-295 = - 25x

x = 11.8

9:00 + 11.8 = 9:11:48 p.m

B.)

180 = - 25x + 425

180 - 425 = - 25x

-245 = - 25x

x = 9.8 minutes

Answers

Answer:it’s B (120 succes and 80 failures for khan academy)

Step-by-step explanation: trust me

The shape of the sampling distribution of [tex]\hat{p}_\text{A}-\hat{p}_\text{B}[/tex] is approximately normal because the number of success in district A is 120

How to determine the shape of the distribution?

The given parameters are:

Proportion of adults in district A = 60%Proportion of adults in district B = 45%Sample size of A, n = 200Sample size of B, n = 100

In the sample size of 200, the number of adults that support a new ballot measure is:

Success = 60% * 200

Success = 120

Those that oppose is

Failure = 200 - 120

Failure = 80

If 45% supports a new ballot measure in district B, then 55% do not support

The difference between those that support and do not support is:

(55% - 45%) * 100 = 10

Hence, the sampling distribution of [tex]\hat{p}_\text{A}-\hat{p}_\text{B}[/tex] is approximately normal

$9,216 in account $1,261 interest

Answers

Answer:

$9,216 in account $1,261 interest.

Step-by-step explanation:

The compound interest is given by:

[tex]a = p(1 + \frac{r}{n})^{nt} [/tex]

P = Principal

r = rate

n = Number of times interest is compounded per unit t

t = time

so:

[tex]a = 8000(1 + \frac{0.05}{1} ) ^{1 .3} \\ a = 9261[/tex]

therefore, the answer is:

$9,216 in account $1,261 interest

FSelect the correct answer. Consider these functions: f(x)=4x^3-10 g(x)=3x-4/2 What is the value of g(f(2))? A. -6 B. 2 C. 19 D. 31

Answers

Answer:

D. 31

Step-by-step explanation:

First we need to find what the value of f(2) is, so we are going to substitute x for 2 in f():

f(2)=4(2)^3-10

= 4(8)-10

= 32-10

= 22

And then we substitute 22 for x in g()

g(22)= (3(22)-4)/2

= (66 -4)/2

= 62/2

= 31
