Answer:

[tex]y = -2x + 5[/tex]

m = -1

b = 5

Step-by-step explanation:

Hello!

Slope - Intercept Form: [tex]y = mx+b[/tex]

The slope of the line is the rate of change, or how the graph changes in y as it changes in x.

Slope can be calculated by the formula: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

We need two points on the line to get the x and y-values. I'm going to choose points (0,5) and (4,-3).

Calculate Slope

The slope is -2.

The y-intercept of the line is where the graph touches the y-axis (x = 0). It can be found by looking at the intersection of the graph and the axis.

The intersection happens at point (0,5), so the y-intercept is 5.

We found m, the slope, to be -2 and b, the y-intercept, to be 5. We can just plug it into the equation format.

Equation: [tex]y = -2x + 5[/tex]

Answer:

[tex]200 cm^2[/tex]

Step-by-step explanation:

A = (1/2)bh

A = (1/2)(18)(30)

A = 270 square cm

A = (1/2)(16)(25)

A = 200 square cm

Answer:

200 square centimeters

Step-by-step explanation:

The area of a triangle can be calculated using the formula: [tex]A = \frac{1}{2}bh[/tex] where b is the base and h is the height. So if the base is 16 cm and the height if 25 cm you simply plug the values into the equation to find the area

Plug Values In:

[tex]A = \frac{1}{2}(16 cm)(25 cm)[/tex]

Multiply 16 cm and 25 cm:

[tex]A = \frac{1}{2}(400 cm^2)[/tex]

Multiply by 0.5 (or technically divide by 2)

[tex]A = 200 cm^2[/tex]

The number of miles the bird can fly for 60 minutes is 20 miles.

A bird can fly 5 miles in 15 minutes.

Let's find the rate before we can find the number of miles the bird can fly in 60 minutes.

Therefore,

rate = distance / time

rate = 5 / 15  = 1 / 3 miles per minutes

Therefore,

1 / 3  = d / 60

cross multiply

60 = 3d

d = 60 / 3

d = 20 miles

Using the linear function given in this problem, the formula underestimates the median weekly earnings in 2013 by $3, as 657 < 660.

The function that estimates the median weekly earnings n years after 1980 is:

W = 13n + 231.

2013 is 2013-1980 = 33 years after 2000, hence the estimate is given by W when n = 33, that is:

W = 13 x 33 + 231 = 660.

657 < 660, hence the formula underestimates the median weekly earnings in 2013 by $3.

Answer:

  f(x) = -5x +48

Step-by-step explanation:

A fairly easy way to write the equation of the perpendicular line is to swap the x- and y-coefficients, negating one of them. Then choose the constant in the equation to make it true at the given point.

In this instance, we find it convenient to leave the coefficient of y as positive.

  5y = x -10 . . . . . . original equation

  y = -5x +c . . . . . . with coefficients swapped, x-coefficient negated

At the given point, the equation becomes ...

  8 = -5(8) +c

The equation of the line is then ...

  y = -5x +48

Answer:

t = 1.322

Step-by-step explanation:

4×(2^t) = 10

2^t = 10/4 = 2.5

t = log2(2.5)

now, the logarithm to the base 2 of 2.5 must be larger than 1, as 2.5 is larger than 2.

so, it can be only the 4th answer option.

now, to actually calculate it :

log2(2.5) = log10(2.5) / log10(2) = 1.321928095... ≈

≈ 1.322

we were correct.

Answer:

t = 1.322

Step-by-step explanation:

Given equation:

[tex]4(2^t)=10[/tex]

Divide both sides by 4:

[tex]\implies \dfrac{4(2^t)}{4}=\dfrac{10}{4}[/tex]

[tex]\implies 2^t=2.5[/tex]

Take natural logs of both sides:

[tex]\implies \ln 2^t = \ln 2.5[/tex]

[tex]\textsf{Apply the natural log power law}: \quad \ln x^n=n \ln x[/tex]

[tex]\implies t \ln 2 = \ln 2.5[/tex]

Divide both sides by ln 2:

[tex]\implies \dfrac{t \ln 2}{\ln 2} = \dfrac{\ln 2.5}{\ln 2}[/tex]

[tex]\implies t= \dfrac{\ln 2.5}{\ln 2}[/tex]

[tex]\implies t=1.321928095...[/tex]

[tex]\textsf{Apply log law}: \quad a^c=b \iff \log_ab=c[/tex]

[tex]\implies \log 2 (2.5)=t[/tex]

Answer:

Step-by-step explanation:

Area of a scaled figure is multiplied by the square of the scale factor; volume is multiplied by the cube of the scale factor.

When dimensions are multiplied by 3, the area is multiplied by 3² = 9.

Area of the larger figure is 9 times that of the smaller one.

When dimensions are multiplied by 3, the volume is multiplied by 3³ = 27.

Volume of the larger figure is 27 times that of the smaller one.

__

Additional comment

In general, the area of a figure is the sum of the products of two orthogonal dimensions. If each of those is multiplied by 3, then the product is multiplied by 3 twice, or 3² = 9.

Similarly, the volume of a figure is the sum of products of three orthogonal dimensions. When those are each multiplied by 3, the product is multiplied by 3 three times, or 3³ = 27.

Answer:

-8

Step-by-step explanation:

Slope = (y1-y2) / ( x1-x2)

            = ( f-4) / (-8 - -6)      =  6

                  (f-4) / -2    = 6

                    f-4 = -12

                     f = - 8

Answer:

f = -8

Explanation:

Find slope:

[tex]\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} = \dfrac{\triangle y}{\triangle x} \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points[/tex]

Here given:

Inserting into slope formula:

[tex]\sf \rightarrow \dfrac{4-f}{-6-(-8) } = 6[/tex]

[tex]\sf \rightarrow \dfrac{4-f}{2 } = 6[/tex]

[tex]\sf \rightarrow 4-f = 12[/tex]

[tex]\sf \rightarrow -f = 12-4[/tex]

[tex]\sf \rightarrow -f =8[/tex]

[tex]\sf \rightarrow f =-8[/tex]

Given: f(x) = 3x² -5x + 4

To find f(-2), simply substitute x = -2 in function f(x).

f(-2) = 3(-2)² -5(-2) + 4

f(-2) = 12 + 10 + 4

f(-2) = 26
