Trust me I just took the exam and got it correct

The answer is in the picture. Let me know if you have any questions.

Answer/Explanation:

When you change the slope, it will affect the steepness of the graph/line.

When you change the y-intercept (b) it will affect where the graph crosses the y axis.

-increasing the y-intercept will make the graph move up and

decreasing will make the y-intercept go down.

Answer:

a) 13 chocolates

b) 92 chocolates

Step-by-step explanation:

Mariana compró 6748 chocolates para donar a un hogar familiar, si hay 512 niños en el lugar,

a) ¿cuántos chocolates tiene cada uno?

Esto se calcula como:

512 niños = 6748 chocolates

1 niño = x

Cruz multiplicar

512x = 6748

x = 6748/512

x = 13,1796875

Por lo tanto, esto significa que cada uno tiene 13 chocolates.

b) Cuantos chocolates quedan

Esto se calcula como:

6748 - (512 × 13)

6748 - 6656

= 92

Por tanto, quedan 92 chocolates

Answer: $100.70

Step-by-step explanation: 6% is equal to 0.06, so you can add multiply the price of the item by 1.06 because that is the base cost plus the tax. Then you get $100.70.

Answer:

100.70

Step-by-step explanation:

95.00*6%

95.00*.06=5.70

95.00+5.70=100.70

Answer:

No

Step-by-step explanation:

When working with negative numbers in terms of depth, greater depth are depicted by values as we move farther to the left of the number line.

With this in mind, - 75 feets is farther to the left of the number line and as such represents a greater depth value Than - 68 feets

Therefore, when expressing depth or elevation distances, the values should be iewwd in absolute terms. Then |75| > |68|. While bearing in mind that depth is downward and thus negative

Answer:

hey

Step-by-step explanation:

Hey there!

The answer is yes, because it does not depend on your height, because you can be any height in any grade (well, maybe not ANY height, because you can't be, like, 100 feet, or 1 inch, but you get the point...).

Hope it helps and have a great day!

To Find:

The Solution of the above inequality

Explanation:

[tex]2\sin(x)+3> \sin^2(x).......(i)\\\text{let} \sin (x) = u\\\Rightarrow 2u+3> u^2\\\Rightarrow u^2-2u-3<0\\\Rightarrow u^2-3u+u-3<0\\\Rightarrow u(u-3)+1(u-3)<0\\\Rightarrow (u+1)(u-3)<0\\\Rightarrow -1<u<3\\\text{and since} \sin(x) = u\\\Rightarrow -1<\sin(x)<3[/tex]

Answer: See explanation

Step-by-step explanation:

The dimensions of the first drawing will be 1/3 the dimensions of the leaf and the dimension of the oak leaf is 5 1/2 inches. Therefore, the dimensions of the 1st leaf:

= 1/3 × 5 1/2

= 1/3 × 11/2

= 11/6

= 1 5/6 inches

This is less than 5 1/2 inches

The dimensions of the second drawing will be 2 1/2 the dimensions of the leaf. This will be:

= 2 1/2 × 5 1/2

= 5/2 × 11/2

= 55/4

= 13 3/4 inches

Thus is greater than 5 1/2 inches

Answer:

The required answer is 100 .

Step-by-step explanation:

Given function to us is ,

⇒ f(n) = 4n + 2 . And we need to find (f • f) (-3)

So , first let's find f•f , which will be ,

⇒ (f • f) = (4n + 2)(4n + 2)

⇒ (f • f) = 4n ( 4n + 2 ) +2 ( 4n + 2)

⇒ (f • f) = 16n² + 8n + 8n + 4

⇒ (f • f) = 16n² + 16n + 4

====================================

Now we need to find (f • f)(-3) . So on substituting f = (-3) , we have :-

⇒ (f • f)(n) = 16n² + 16n + 4

⇒ (f • f)(-3) = 16*(-3)² + 16*(-3) + 4

⇒ (f • f) (-3) = 16* 9 - 48 + 4

⇒ (f • f)(-3) = 144 - 44

⇒ ( f • f) (-3) = 100

Step-by-step explanation:

Answer: This means that the population increased a 20% between the year 2000 and the year 2010.

Step-by-step explanation:

In this case, we have that 25,000 is the 100%.

Now we want to know which percentage represents 30,000

Let's suppose that the percentage is X.

Then we can have a system of equations:

30,000 = X

25,000 = 100%

To find the value of X, we can take the quotient of these two equations:

30,000/25,000 = X/100%

(30,00/25,000)*100% = X = 120%

Then in the 2000 we had a 100%, and in the 2010 there was a 120%.

The difference is:

120% - 100% = 20%

This means that the population increased a 20% between the year 2000 and the year 2010.

Answer:

Step-by-step explanation:

180°(n - 2)

180°(5 - 2) = 540°

540° - (112° + 98° + 110° + 118°) = 102°

q = 28°

r = 32°

s = 78°

t = 118°

u = 50°
