Answer:

The function that is shown in the graph is:

y= -cos x

Step-by-step explanation:

We are given a graph of a function we have to recognize which function is represented by the given graph.

Clearly we could observe from the graph that the function takes the value -1 at x=0.

Hence, the function which satisfy this condition is:

y= -cos x

( since at x=0

y= -cos 0=-1

Also at x=π

we get

y= -cos(π)=-(-1)=1

similarly at x= -π

we get:

y= -cos(-π)= -(-1)=1)

Answer:

C) 52 m²

Step-by-step explanation:

A = 2(lw + lh + wh)

l = 4m

w = 3m

h = 2m

A = 2(4m×3m + 4m×2m + 3m×2m)

= 2(12m² + 8m² + 6m²)

= 2×26m²

= 52m²

A person owes $1000 on a credit card that charges an interest rate of 2% per month

adelina 88 [10]

Credit card balance each month:

First month: 1020 .00

Second month: 1040.4 0

Third month: 1061,208

Fourth month: 1082.43

Here we have to calculate the interest and add it to capital.

That is, 2% of 1000

First month:

Interest = 1000 (2/100)

Odds1 = 1020

Second month

Capital 1020

Interest = 1020 x 0.02 = 20.4

Odds2 = 1040.4

Third month

Capital = 1040.4

Interest = 1040.4 x 0.02 = 20.808

Odds3 = 1061,208

Fourth month

Capital = 1061,208

Interest = 1061.208 x 0.02 = 21.22

Odds = 1082.43

Therefore the credit card balance each month:

First month: 1020 .00

Second month: 1040.4 0

Third month: 1061,208

Fourth month: 1082.43

Solving systems by Substitution Homework y=x+4 y=x-3

zvonat [6]

There is no solution for this equation since they have the same slope, x/1. The only difference between these two is that their y intercepts are different meaning that they will be parallel lines that will never intersect among one other. For example, think of it as two separate lines that are have the same slope and never gain more distance/units from one another.

Solve:

To solve, you have to get one of this equations into a Ax+By=C equation form, standard equation. Let’s change y=x+4 into a standard equation.

We have to get x and y together and 4 as C.
So let’s subtract x from both sides;

y=x+4
-x -x
————————
-x+y=4

This is a standard equation.

Now let’s substitute.

take the standard equation and plug in y which is x+4 since there is a equation meaning it’s y=x+4

-x+(x+4)=4

Let’s simplify this mess.

-x+x equals 0. So we are left with 4=4.

Subtract 4 from both sides and we get 0=0

This means there is no solution. Hoped this helped.
