Answer: OPTION D .

Step-by-step explanation:

1. By definition the function cut or intersects the y-axis when the value of x is equal 0 (x=0).

2. Therefore, you can observe the table given in the problem and see the value of y when x is equal to zero.

3. Keeping this on mind you can see that when x=0, y=8.

Therefore, you can conclude that the y-intercept in the table is 8.

4. As you can see in the graph, the y-intercept is at 5.

5. Then, since 5<8, the answer is the option D

Answer:

Option D is correct

Step-by-step explanation:

The y-intercept is the point where the graph of a function crosses the y-axis. At this point, the x-coordinate is usually zero. Thus, the y-intercept of the function on the table is 8 while on the graph this value is 5.

if j is 21 inches, k is 12 inches, and angle M measures 62 degrees, then find m using the Law is Cosines. round your answer to t

AURORKA [14]

Answer:

18.7

Step-by-step explanation:

The Law of Cosines is $c^2=a^2+b^2-2ab cos(C)$ , where c is the unknown side length of a triangle, a and b are the remaining two side lengths, and C is the angle opposite to side c. To answer this question just plug in the known values:

$m^2=21^2+12^2-2(21)(12) cos(62)$

Simplify:

$m^2=441+144-504 cos(62)$

$m^2=585-504 cos(62)$

$m=\sqrt{585-504cos(62)}$

m≈18.665...

When rounded to the nearest tenth, m=18.7

Trapezoid MNPQ is similar to Trapezoid RSTU. What is the length of the "x" on the misside side NP ? Also, what is the length of

ivolga24 [154]

Answer:

$x = 15$

$y = 25$

Step-by-step explanation:

Given

See attachment for MNPQ and RSTU

Required

Find x and y

To solve this question, we make use of equivalent ratios of corresponding side lengths.

The ratio of corresponding sides are:

$MN : RS$

$NP : ST$

$PQ : TU$

$MQ : RU$

From the attachment, we have:

$MN : RS \to 18 : 30$

$NP : ST \to x : 25$

$PQ : TU \to 15 : y$

To solve for x, we equate $MN : RS$ and $NP : ST$

$18 : 30 = x : 25$

Express as fraction

$\frac{18 }{ 30 }= \frac{x }{ 25}$

Make x the subject

$x = 25 * \frac{18 }{ 30 }$

$x = \frac{25 * 18 }{ 30 }$

$x = \frac{450}{ 30 }$

$x = 15$

To solve for y, we equate $MN : RS$ and $PQ : TU$

$18 : 30 = 15 : y$

Express as fraction

$\frac{18 }{ 30 }= \frac{15 }{ y}$

Make y the subject

$y = 15 * \frac{30 }{ 18 }$

$y = \frac{15 *30}{ 18 }$

$y = \frac{450}{ 18 }$

$y = 25$

Help please (will chose brainliest)

goldfiish [28.3K]

Answer:

LEts start with 10^1

If we have positive exponent then we add zeros

10^1= 10

$10^2=100$ (Put 2 zeros because exponent is 2)

$10^3=1000$ (Put 3 zeros because exponent is 3)

$10^4=10000$ (Put 4 zeros because exponent is 4)

$10^5=100000$ (Put 5 zeros because exponent is 5)

For negative exponent , we make a fraction . we put 1 at the top always and number as the bottom

$10^{-1}=\frac{1}{10}$ (Put 1 zero at the bottom because exponent is -1)

$10^{-2}=\frac{1}{100}$ (Put 2 zeros at the bottom because exponent is -2)

$10^{-3}=\frac{1}{1000}$ (Put 3 zeros at the bottom because exponent is -3)
