Answer 1

Answer:

The measures of angles A, B, and C are respectively 21°, 125°, and 34°

Step-by-step explanation:

Equations

We are given some conditions applying to the internal angles on a triangle ABC.

The measure of angle A is 13 less than the measure of angle C.

The measure of angle B is 11 less than 4 times the measure of angle C

Let x = measure of angle C

The first conditions states:

[tex]m\angle A = x-13[/tex]

The second conditions states:

[tex]m\angle B = 4x-11[/tex]

The sum of all angles must be 180°, thus:

[tex]x - 13 + 4x - 11 + x = 180[/tex]

Simplifying:

6x -24 = 180

Adding 24:

6x = 204

Dividing by 6:

x = 204/6

x = 34

[tex]m\angle C = x = 34^\circ[/tex]

[tex]m\angle B = 4x-11 = 4*34-11 = 125^\circ[/tex]

[tex]m\angle A = x - 13 = 34 - 13 = 21^\circ[/tex]

The measures of angles A, B, and C are respectively 21°, 125°, and 34°

c-y+3=-4(x+6)
d-Y-6=-4(x+3)​

Answers

Answer:

1+1=magelan

2plus2 lapulapu

Answer:

b and d

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, 6) and (x₂, y₂ ) = (- 2, 2) ← 2 points on the line

m = [tex]\frac{2-6}{-2+3}[/tex] = - 4

Using (a, b ) = (- 3, 6 ), then

y - 6 = - 4(x - (- 3)), that is

y - 6 = - 4(x + 3) → d

Using (a, b ) = (- 2, 2 ), then

y - 2 = - 4(x - (- 2)) , that is

y - 2 = - 4(x + 2) →b

Is a repeating decimal a rational number
A. Yes because it can be written as a/b and a and b are integers and b =0
B. Yes because it can be written in the form a•b where a and b are integers

Answers

Answer:

Option A

Step-by-step explanation:

The answer to this question is option A or "Yes because it can be written as a/b and a and b are integers and b =0." Any number that can be written as a fraction is a rational number. In this case repeating decimals can be written as a fraction using different types of algebraic methods making it a rational number.

i need help with this slope problem

Answers

Answer:

It is the first one and the second one. If it is the same, then the slope will be constant.

Step-by-step explanation:

Answer:

I think it's the second one ( Any two points on the line will produce the same slope)

Step-by-step explanation:

Any two points on a line will ALWAYS have the same slope. There's no way that it won't be that way. That's why you are able to choose any two points on a graph to find a slope.

For the first one, i think it's wrong because although the slope is 1/2, Jennifer used the slope 2/4 while Marshall used 1/2. Even though it's the same, Jennifer didn't technically use 1/2...

And the third option is wrong. The slope isn't 2.

Hopefully this wasn't confusing... :)

The answer to the same three questions is

Answers

The slope of the line is 3

The difference between the consecutive term of the sequence is (1, 3)

To get the slope of the graph, we will use the coordinate points (2, 10) and  (3, 13)

Slope = 13-10/3-2

Slope = 3/1

Slope = 3

Hence the slope of the line is 3

The difference in the term for the x-coordinate is given as:

x = 3 - 2 = 4 - 3  = 5 -4  = 1

The difference in the term for the y-coordinate is given as:

x = 13 - 10 = 16 - 13  = 19 -16  = 3

Hence the difference between the consecutive term of the sequence is (1, 3)

A rectangular carpet measures 12 m by 5 m.
Part of the carpet is covered by a square rug of length 2 m.
What fraction of the carpet is covered by the rug? Give your answer in its simplest form.

Answers

I'm pretty sure the answer is 1/15 or 4/60 because the whole carpet measures 60m and the covered part's area is 4m and that would be 4/60 but simplified 1/15.  Sorry if this is wrong!

To find the fraction of the carpet covered by the rug, we need to determine the area of the rug and divide it by the total area of the carpet.

The area of the square rug can be calculated by squaring its side length: 2m x 2m = 4m². The total area of the rectangular carpet can be found by multiplying its length and width: [tex]12m x 5m = 60m²[/tex]. To find the fraction, divide the area of the rug by the area of the carpet: 4m² / 60m².

To simplify the fraction, we can find the greatest common divisor (GCD) of 4 and 60, which is 4. Dividing both the numerator and denominator by the GCD, we get: [tex]4m² ÷ 4 / 60m² ÷ 4 = 1m² / 15m²[/tex] . Therefore, the fraction of the carpet covered by the rug is 1/15, which means that 1/15th of the carpet is covered by the rug.

what is the directrix of a parabola with focus (4,-1) and a vertex at (4,-5)?​

Answers

Answer:

                y = -9

Step-by-step explanation:

The directrix is at the same distance from the vertex as the focus but on the opposite side of the vertex.

x coordinate the same for a focus and a vertex (4) means the parabola opens up or down and the directrix is parallel to the x-axis.

y coordinate of the focus greater than y coordinate of the vertex means the parabola opens up and the directrix lays below the vertex.

-1-(-5) = - 1 + 5 = 4

so: - 5 - 4 = -9 is the y coordinate of points of the directrix

Jordan throws a ball from a cliff 12 feet above the ground with an initial velocity of 32 feet per second. In the following functions, h(t) represents the height of the ball above the ground, in feet, with respect to time, t, in seconds, after the ball was thrown. Which of the following functions models the amount of time the ball is in the air?

h(t)= -4(t-1)^2 +3
h(t)= -16(t-1)^2 -4
h(t)= -16(t-1)^2 +12
h(t)= -16(t-1)^2 +28

Answers

Answer:

Your answer will be the third function

Step-by-step explanation:

The base function you need to know is h(t)= 1/2at^2

Your acceleration in this problem is going to be gravity which they give to you, 32 feet per second squared. Since the ball is falling, it means it will have negative acceleration. Now you have the equation h(t)= -16t^2. The final step is to add the initial height from which the ball was dropped giving you: h(t)= -16t^2 +12
