Write the equation of an exponential function that passes through the points (2,48) and (5,750).

1 answer:

7 0

Ok, so the function form is y = a * bx.
Substitute in the values:
750 = a * b5
and
48 = a * b2
Then divide the two equations:
750/ 48 = (a * b5) / (a * b2)
So:
15.625 = b3
Take the cube root of both sides:
2.5 = b
Now, substitue b into one of the equations (the one with 48 has smaller numbers and is easier to work with.)
48 = a * 2.52
Simplify.
48 = a * 6.25
Divide both sides by 6.25
7.68 = a
Now substitute in a and b to write the exponential function:
y = 7.68 * 2.5x

4n+3< 6n+8 -2n what is n

PolarNik [594]

Answer:

$8>3$

Step-by-step explanation:

STEP 1: Rewrite so n is on the left side of the inequality.

$6n+8-2n>4n+3$

STEP 2: Subtract 2 n from 6 n .

$4n+8>4n+3$

STEP 3: Move all terms containing n to the left side of the inequality.

$8>3$

Find the measure for angle f 46 34 122 58

xxMikexx [17]

Answer:

$\angle f = 122\degree$

Step-by-step explanation:

$\angle d = 58\degree$ (vertical angles)

$\angle f+\angle d= 180\degree$

(Interior angles on the same side of transversal)

$\angle f+ 58\degree = 180\degree$

$\angle f = 180\degree-58\degree$

$\huge \orange {\boxed {\angle f = 122\degree}}$

Of all postsecondary degrees awarded in the United States, including master's and doctorate degrees, 21% are associate's degrees

icang [17]

The conditional probability that a degree is earned by a person whose race is White, given that it is an associate's degree, is 57.14%.

Given that of all postsecondary degrees awarded in the United States, including master's and doctorate degrees, 21% are associate's degrees, 58% are earned by people whose race is White, and 12% are associate's degrees earned by Whites, to determine what is the conditional probability that a degree is earned by a person whose race is White, given that it is an associate's degree, the following calculation should be performed:

A cross multiplication must be applied to obtain the percentage of whites who have obtained an associate degree.
21 = 100
12 = X
12 x 100/21 = X
1200/21 = X
57.14 = X

Therefore, the conditional probability that a degree is earned by a person whose race is White, given that it is an associate's degree, is 57.14%.

Find the measure of an angle whose measure is 60 degrees more than the measure of its complement

Natasha2012 [34]

Two complementary angles add up to 90 degrees. Hence, the problem can be set up and solved. Let x represents one angle and 5x represent the angle that is 5 times greater:x + 5x = 90 (simplify)6x = 90 (next divide both sides by 6 to find the value of x [the smaller angle])x = 15 (this is the smaller angle, next subtract 15 from 90 to find the greater angle)90 - 15 = 75 (this is the greater angle which is 5 times that of its complement) 90 take away 73...
