You can model the population of a certain city between the years 1965 and 1995 by the radical function P(x)=75,000^3 SQRT x-1940

. Using this model, in what year was the population of that city 245,000?
a)1973
b)1975
c)1979
d)1970

The model is p(x) = 75,000 ∛(x - 1940)

Now use p(x) = 245,000 and solve for x

245,000 = 75,000 ∛(x - 1940) =

245,000 / 75,000 = ∛(x - 1940)

49/15 = ∛(x - 1940)

x - 1940 = [49/15]^3 = 34.86

x = 1940 + 34.86 = 1974.85

Then, the answer is 1975 (option b)

Brrunno [24]

Answer:

25 questions.

Step-by-step explanation:

Correct answer = 18

The percent score of the correct answers is 72%.

Let there are x questions in the test. So,

According to the given condition,

72\%\ of\ x=18\\\\\dfrac{72}{100}x=18\\\\x=\dfrac{18\times 100}{72}\\\\x=25

Hence, there were 25 questions in the geometry test.

Which equation represents a line passing through the point (8,33) with a slope of 3?
Delvig [45]

The slope intercept form of equation of required line is y = 3x + 9

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If  \theta is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m =  tan\theta

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

Here,

Slope = 3

The line passes through (8, 33)

Equation of required line

y - 33 = 3(x - 8)

y - 33 = 3x - 24

y = 3x - 24 + 33

y = 3x + 9
