Step-by-step explanation:

If two secants are drawn from a point outside the circle, then the product of the lengths of one secant and its external segment equals the product of the lengths of the other secant and its external segment

Let us solve the question.

∵ There is a circle in the given figure

∵ There are two secants intersected at a point outside the circle

∵ The length of one of them = 8

∵ The length of its external segment = x

∵ The length of the other secant = 4 + 8 = 12

∵ The length of its external segment = 4

→ By using the rule above

∴ 8 × x = 12 × 4

∴ 8x = 48

→ Divide both sides by 8

∴ x = 6

Step-by-step explanation:

7(p-9)=-34.3

first you want to apply what is outside of the parenthesis to the inside of the parenthesis. After applying you would get

7p-63=34.3

Next you wanna get the variable to one side and the whole numbers to the other side. to do this you add 63 to each side, you end up with

7p=28.8. Then you want to get p by itself. In order for this to happen you divide each side by 7 to get p=4.114285714

Answer:

yes they form a proportion

Step-by-step explanation:

1 to 3 and 7 to 21 are equal

we can check this by multiplying each number in the 1 to 3 ratio by 7 to make it equal with the other ratio, 7 to 21.

Step-by-step explanation:

B is wrong because it's saying to multiply the cost by $7.35.

C is wrong because it's telling you to add the amount of grams to $7.35.

A is the correct answer because you have to mutiply the cost by the grams which is what a number by a variable means.

Answer:

  15 seconds

Step-by-step explanation:

Put the given heights in the equation and solve for t.

  h(t) = -16t² +3600

  0 = -16t² +3600 . . . . h(t) = 0 at ground level

  16t² = 3600 . . . . . . . add 16t²

  t² = 3600/16 = (60/4)² = 15² . . . . . divide by 16

  t = 15 . . . . . . . . . . . . take the square root

It will take 15 seconds for the phone to hit the ground.

Answer:

y- intercept = 1

Step-by-step explanation:

The y- intercept is the point on the y- axis where the graph crosses.

This occurs when the x- coordinate is 0

From the table the point (0, 1 ) is where the graph crosses the y- axis

Then y- intercept = 1

13/14 is greater than 25/28? true

21/45 is less than 4/9? false

5/6 is greater than 11/12? false

4/5 is less than 8/25? false

Answer:

just go down negative 7 on the y int and that's ur starting point, then go down -1 and over 4 to the right, repeat this step 2 or 3 times then draw ur line.

The line with the equation y= - 1/4x -7 graph is shown below.

Suppose the considered function whose graph is to be made is

f(x)

The values of 'x' (also called input variable, or independent variable) are usually plotted on horizontal axis, and the output values

f(x)

are plotted on the vertical axis.

They are together plotted on the point

(x,y) = (x, f(x))

This is why we usually write the functions as:

y = f(x)

Given;

y= - 1/4x -7

Now, the graph of the function is given in the image.

Answer:

B) -1/2

C) {30, 150}

Step-by-step explanation:

Question 3)

We can see that the angle equals 210* which equals 7pi/6 (in radians)

The coordinates would be [tex](\frac{-\sqrt{3} }{2}, \frac{-1}{2})[/tex]

Since the problem is asking for sinθ, we will use -1/2 (the y-coordinate)

So the answer is B) -1/2..

Question 4)

If the criteria of the answer is that it must be between 0 < θ < 360 and it must have a y-value of 1/2 in its coordinate (sinθ = 1/2), then we will choose angles that meet this criteria. When we look at the unit circle (see the attached) we can see that only the angles of 30* and 150* match this answer, so our answer is c.
