Two angles of a triangle are the same size. The third angle is 3 times as large
as the first. How large are the angles?

Answers

Answer 1
Use x to represent the first two angles. If the third angle is 3 times as large as the first, it can be represented as 3x. So, your angles are x, x, and 3x. These need to all add to 180 degrees, since it’s a triangle.

x + x + 3x = 180 —> Simplify the left side.
5x = 180 —> Divide by 5.
x = 36

So the first two angles are 36 degrees, and the third angle is 3 times that, which is 108 degrees.

Use the remainder theorem and synthetic division to find f(k) for the given value of k.

Answers

Answer:

3

Step-by-step explanation:

Given that,

[tex]f(x) =-x^3-8x^2-15x+3[/tex]

We need to find the value of  f(x) when k = -5

Put x = -5 in th  given function.

So,

 

[tex]f(-5) =-(-5)^3-8(-5)^2-15(-5)+3\\\\=3[/tex]

Hence, the value of the given function is equal to 3.

Write the equation of the following circle in general form and standard form. Show your work.

Answers

Answer:

Step-by-step explanation:

Standard equation of a circle is given by,

(x - h)² + (y - k)² = r²

Here, (h, k) is the center of the circle.

From the graph given in the picture,

Center of the circle → (-1, 1)

Radius of the circle = 3 units

Therefore, standard equation of the circle will be,

(x + 1)² + (y - 1)² = 3²

(x + 1)² + (y - 1)² = 9

General equation of the circle is the expanded form of the standard equation.

x² + 2x + 1 + y² + 1 - 2y = 9

x² + y² + 2x - 2y + 2 = 9

x² + y² + 2x - 2y - 7 = 0

Therefore, general equation of the given circle is,

x² + y² + 2x - 2y - 7 = 0

Solve for x.
Question 4 options:

Answers

Answer:

x = -9

Step-by-step explanation:

Given:

BC = x + 19

ST = x + 29

Required:

Value of x

Solution:

Midsegment theorem states that the midsegment of a triangle = ½ of the length of its third side

Thus:

BC = ½(ST)

Substitute

x + 19 = ½(x + 29)

Multiply both sides by 2

2(x + 19) = x + 29

2x + 38 = x + 29

Collect like terms

2x - x = -38 + 29

x = -9

What is the rate of change of the function y - 6x + 3?​

Answers

Answer:

6

i think the - was meant to be an = instead of -

Step-by-step explanation:

rate of change is the same as slope

that is slope-intercept form.

y=mx+b

m is slope

slope= 6

Answer:

The rate of change is 6

Step-by-step explanation:

Set the equation equal to 0:

y-6x+3=0

Now solve for y because we want the equation in y=mx+b form where m is the rate

Subtract 3:

y-6x=-3

add 6x

y=6x-3

Now in y=mx+b form

m would equal 6

Find the probability of drawing a 10 from a standard deck
of 52 cards,

Answers

Answer:

4/52 or 1/13 (simplified)

Step-by-step explanation:

There are 4 "10's" in a pack.

This means you have the chance to pick 4 10's.

So out of 52 cards, you can get 4.

4/52 -> Which can be simplified to 1/13.

This is the probability of getting a 10 (once) in a standard deck of cards.

The probability of drawing a 10 from a standard deck of 52 cards is 1/13.

Number of 10's in a standard deck of 52 cards  =4

Total cards =52

What is probability?

Probability is the measurement of the possibilities of events.

P(event) =Favorable outcomes/ Total possible outcomes

Here, Favorable outcomes =4

Total possible outcomes =52

P(10) =4/52

P(10) =1/13

So, the probability of drawing a 10 from a standard deck of 52 cards =1/13

Thus, the probability of drawing a 10 from a standard deck of 52 cards is 1/13

a person invested $330 in an account growing at a rate allowing the money to double every 8 years. Write a function showing the amount of money in the account after tt years, where the annual growth rate can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage of growth per year, to the nearest hundredth of a percent.

Answers

Answer:

The percentage of growth is of 9.05%.

The amount of money in the account after t years is given by [tex]P(t) = 330(1.0905)^t[/tex]

Step-by-step explanation:

Amount of money after t years:

The amount of money in an account after t years is given by:

[tex]P(t) = P(0)(1+r)^t[/tex]

In which P(0) is the initial deposit and r is the growth rate, as a decimal.

Money doubles every 8 years.

This means that [tex]P(8) = 2P(0)[/tex]. So

[tex]P(t) = P(0)(1+r)^t[/tex]

[tex]2P(0) = P(0)(1+r)^8[/tex]

[tex](1+r)^8 = 2[/tex]

[tex]\sqrt[8]{(1+r)^8} = \sqrt[8]{2}[/tex]

[tex]1 + r = 2^{\frac{1}{8}}[/tex]

[tex]1 + r = 1.0905[/tex]

[tex]r = 1.0905 - 1[/tex]

[tex]r = 0.0905[/tex]

The percentage of growth is of 0.0905 = 9.05%.

Person invested $330

This means that [tex]P(0) = 330[/tex]

So

[tex]P(t) = P(0)(1+r)^t[/tex]

[tex]P(t) = 330(1+0.0905)^t[/tex]

[tex]P(t) = 330(1.0905)^t[/tex]

The amount of money in the account after t years is given by [tex]P(t) = 330(1.0905)^t[/tex]
