Answer:

It is dilated by the scale factor

Step-by-step explanation:

For example is one line is 2 units long and  the image of that line was 4 units long the scale factor would be 2. (2 x 2 = 4.) If it was the other way around with the 4 as the original line and the 2 as the image line the scale factor would be 1/2. (1/2 x 4 = 2)

Answer:

260 units

explanation:

A dilation with a scale factor is noting but an increase in size of geometrical figure by a certain value.in the circumstances the line AB is 5 units. being a line AB has no width, so it only increases in length. if you want new length, it's simple.all that's nessary multiply the orgin length by the scale factor.

5.52=260

the solution is 260 units.

Here, we want to graph the given line

Mathematically, to graph a line, we will

need to work with the intercepts

The general equation of a straight line is;

y = mx + b

m

is the slope and b is the y-intercept

with respect to the question, 4 is the y-intercept

we have this point as (0,4)

To get the x intercept, we will need to substitute 0 for the value of y

So, we have ;

0 = -x + 4

x = 4

The x-intercept too is 4

This is the point (4,0)

So by joining the points (0,4) and (4,0);

we have successfully graphed the line

The ratio as per diagram:

Equivalent ratio from the options is:

There are no matches for 9, 7, 20, 17

Answer:

Equivlent ratio is 8:16

Step-by-step explanation:

8:16 can be further simplified into 2:4 but 8:16 is correct choice.

Here , we are going to use Trigonometric ratios.

In given right angled ∆ ;

[tex]{:\implies \quad \sf \dfrac{x}{18}=\sin (60^{\circ}) \quad \bigg\{ \because \sin (\theta)=\dfrac{P}{H}\bigg\}}[/tex]

[tex]{:\implies \quad \sf x=\dfrac{18\sqrt{3}}{2} \quad \bigg\{\because \sin (60^{\circ})=\dfrac{\sqrt{3}}{2}\bigg\}}[/tex]

[tex]{:\implies \quad \bf \therefore \quad x=9\sqrt{3} \: units}[/tex]

Also;

[tex]{:\implies \quad \sf \dfrac{y}{18}=\cos (60^{\circ}) \quad \bigg\{ \because \cos (\theta)=\dfrac{B}{H}\bigg\}}[/tex]

[tex]{:\implies \quad \sf x=\dfrac{18}{2} \quad \bigg\{\because \cos (60^{\circ})=\dfrac{1}{2}\bigg\}}[/tex]

[tex]{:\implies \quad \bf \therefore \quad y=9 \: units}[/tex]

Hence , The required values for x and y are 9√3 and 9 units

Answer:

y= -3x

Step-by-step explanation:

Find the slope

-9-0/3-0 = -9/3

Simplify = -3

Plug into point-slope formula

y-y1=m(x-x1)

y-0=-3(x-0)

y= -3x

Answer:

32/b

Step-by-step explanation:

b will be divided out of 32

Given:

Number of spheres = 2

Number of prisms = 3

Number of pyramids = 5

To find:

The probability that a pyramid will be selected.

Solution:

We have,

Favorable outcomes = Number of pyramids

                                  = 5

Total outcomes = Total number of figures

                          = [tex]2+3+5[/tex]

                          = [tex]10[/tex]

Now, the required probability is:

[tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]

[tex]\text{Probability}=\dfrac{5}{10}[/tex]

[tex]\text{Probability}=0.5[/tex]

Therefore, the probability that a pyramid will be selected is 0.5.

Answer:109.1 feet

Step-by-step explanation:

What function uses the ADJACENT and the HYPOTENUSE?

\text{SOH-CAH-TOA}

SOH-CAH-TOA

\cos N = \frac{\text{adjacent}}{\text{hypotenuse}}=\frac{73}{x}

cosN=

​

\cos 48=\frac{73}{x}

cos48=

​

x\cos 48=73

xcos48=73

Cross multiply.

\frac{x\cos 48}{\cos 48}=\frac{73}{\cos 48}

The graph is missing, so i have attached it.

Answer:

$0.40 per minute

Step-by-step explanation:

From the attached graph, we can see that it is a linear graph.

Thus, to find the unit rate paid by Ken, we will calculate the slope by picking two coordinate points with thick dots on the blue and calculating it.

Point 1 = (15, 6)

Point 2 = (35, 14)

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

Slope = (14 - 6)/(35 - 15)

Slope = 8/20

Slope = $0.40 per minute

Answer:  Here is the answers after I graphed it

1: The equation of the line that has a slope of 1 and a y-intercept of -1 is:

y=1x-1.

...............................................................................................................................................

2: The equation of the line that has a slope of 1 and a y-intercept of -3 is:

y=1x-3.

Step-by-step explanation:  I graphed it

1: You want to find the equation for a line that has a slope of 1 and a y-intercept of -1.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

All you really have to do here is

replace m with 1, which is the slope you gave, and

replace b with -1, the y-intercept you gave,

in the equation y=mx+b.

The equation of the line that has a slope of 1 and a y-intercept of -1 is:

y=1x-1.

...............................................................................................................................................

2: You want to find the equation for a line that has a slope of 1 and a y-intercept of -3.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

All you really have to do here is

replace m with 1, which is the slope you gave, and

replace b with -3, the y-intercept you gave,

in the equation y=mx+b.

The equation of the line that has a slope of 1 and a y-intercept of -3 is:

y=1x-3.

Step-by-step explanation:

Answer:

. g(x)=2x^2+10x+12=2x²+6x+4x+12=2x(x+3)+4(x+3)

=(x+3)(2x+4)=2(x+2)(x+3)

Answer:

2(x + 3)(x + 2)

Step-by-step explanation:

All three terms of g(x)=2x^2+10x+12 have the factor 2, so

g(x)=2x^2+10x+12 = 2(x^2 + 5x + 6).

This can be factored further, into:

                                 2(x + 3)(x + 2)

Step-by-step explanation:

radius of circle = 5 yd ------ ( given )

height of triangle = 16 yd --- ( given )

base of triangle = 16 yd ----- ( given )

area of triangle = 1/2 × base × height

= 1/2 × 16 × 16

= 128 yd²

area of circle = π × radius²

= 3.14 × 5 × 5 --- ( π = 3.14 )

= 78.5 yd²

area of shaded portion = area of triangle - area of circle

area of shaded portion= 128 yd²-78.5 yd²

area of shaded portion = 49.5 yd²
