Step-by-step explanation:

I just want the points. im taking the quiz rn.

Answer 2

From the given options, the only even function is the cosine function, so the correct option is A.

Which of the options is an even function?

First, an even function is a function with the property:

f(x) = f(-x)

So these functions are symmetrical across the y-axis.

Is ratter easy to remember that the sin function is actually odd, this means that:

sin(-x) = -sin(x).

Then the tangent function (and the cotangent function) are also odd, because:

tan(x) = sin(x)/cos(x).

In the other hand, for the cosine function we have:

cos(-x) = cos(x)

And as shown in the graph below, it is symmetrical across the y-axis.

Then we conclude that the correct option is A.

A triangle has angles of 124°, 28° and 28°.
Using the given angle measures, how many triangles can be formed (one unique, more than one, or none)? Explain your answer.

Answers

Answer:

1 unique

Step-by-step explanation:

Given the angles of the triangle in the question, only one unique triangle can be formed.

This is because, if we look at the angles given, we can see that we have two of the angles equal.

This will give rise to the formation of an isosceles triangle which is a triangle in which two of the sides are equal in length

The equal angles made it in such a way that this is the only type of triangle that can be formed from the angles given

Amy reached into a bag, recorded the color of the tile she picked, returned the tile and drew again. These are the tiles she has drawn so far: red, red, blue, yellow, blue, red, green, red, blue, green Based on this data, a. What is the probability that her next draw will be red? 40 b. What is the probability that her next draw will NOT be blue? c. If she draws 70 more times, how many times would you expect a green?

Answers

Answer:

A) 0.7

B) 0.2

C) 14 times

Step-by-step explanation:

We are told that the tiles she has drawn so far are;

red, red, blue, yellow, blue, red, green, red, blue, green.

In this, we have 10 number.

So for the first 10 number of tiles, she had:

4 red tiles

3 blue tiles

1 yellow tile

2 green tiles

A) probability that her next draw will be red = number of red tiles/total number of initial tiles drawn = 4/10 = 0.4

B) probability that her next draw will NOT be blue = number of tiles that are not blue/total number of initial tiles drawn = 7/10 = 0.7

C) Probability that the next draw will be green = number of tiles that are green/total number of initial tiles drawn = 2/10 = 0.2

Now, if she draws 70 more times, number of times she will expect a gree tile = 0.2 × 70 = 14 times

When Ava went to bed, the temperature was 3°F. When she woke up, the temperature had decreased by 6°F. What was the temperature when Ava woke up?​

Answers

Answer:

[tex]T_f=9^{\circ} F[/tex]

Step-by-step explanation:

It is given that,

Initial temperature, [tex]T_i=3^{\circ} F[/tex]

The decrease in temperature when she woke up is, [tex]\Delta T=6^{\circ} F[/tex]

We need to find the temperature when Ava woke up.

Change in temperature = final temperature-initial temperature

[tex]6\ ^{\circ}F=T_f-3^{\circ}F\\\\T_f=9^{\circ} F[/tex]

So, when she woke up the temperature was 9°F.

The temperature when Ava woke up is -3°F

What is Integers?

Integers come in three types:

Zero (0)Positive Integers (Natural numbers)Negative Integers (Additive inverse of Natural Numbers)

Given:

When Ava went to bed, the temperature was 3°F.

and, When she woke up, the temperature had decreased by 6°F.

So, the temperature when Ava woke up

= 3 - 6

= -3°F

Hence, the temperature when Ava woke up is -3°F

mariana wants to put 6 3/4 feet of border across the top of a wall she has 3 6/7 feet of border. what fraction of the project can she complete

Answers

Answer:

[tex]\frac{4}{7}[/tex]

Step-by-step explanation:

Length of the border Mariana wants to put across the top of a wall = [tex]6\frac{3}{4}[/tex] feet

                                                                                                               = [tex]\frac{27}{4}[/tex] feet

If she has the length of the border = [tex]3\frac{6}{7}[/tex] feet

                                                         = [tex]\frac{27}{7}[/tex] feet

Therefore, fraction of the project can be completed = [tex]\frac{\frac{27}{7}}{\frac{27}{4} }[/tex]

                                                                                       = [tex]\frac{27}{7}\times \frac{4}{27}[/tex]

                                                                                       = [tex]\frac{4}{7}[/tex]

Fraction of the project can be completed = [tex]\frac{4}{7}[/tex]

What is the measurement for the exterior angle

Answers

First we find [tex]\angle ACB[/tex]

[tex]\angle ACB = 180 - (4x - 100) = 180 - 4x + 100 = 280 - 4x[/tex]

Then we find a equation for all the interior angles

[tex]180 = \angle ACB + \angle BAC + \angle ABC\\= 280 - 4x + x + 20 + x\\300 - 2x[/tex]

We solve for x

[tex]180 = 300 - 2x\\180 - 300 = -2x\\-120 = -2x\\2x = 120\\x = 60\\[/tex]

Now we find the exterior angle

[tex]\angle DCB = 4x - 100 = 4 \cdot 60 - 100 = 240 - 100 = 140[/tex]

Because you payed $5,000 for a car and $1,500 more for a down payment, so we would have to add.

$5,000 (cost of car) + $1,500 (cost of down payment) = $6,500 (total pay)

Coats are highly seasonal items. Their highest selling month is 450% of their lowest selling month. During the lowest selling month, they sell 360 units. How many units do they sell during the peak month?
a) 820
b) 1,420
c) 1,620
d) 2,820

Answers

Answer:

1620

Step-by-step explanation:

450*360/100. xd xd xd

The number of units they sold during the peak month is 1620 units.

Given that, the highest selling month of coats is 450% of their lowest selling month. During the lowest selling month, they sell 360 units.

We need to find out how many units do they sell during the peak month.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the highest number of coats sold in the peak month be x.

So, x= 450% of 360

⇒x=4.5 × 360

⇒x=1,620

Therefore, the number of units they sold during the peak month is 1620 units.
