Answer: We're given a parabola

y=x^2-4

and a line

y = 2x+b

The zeros of the parabola are

0=x^2-4

4=x^2

x=\pm 2

We see that (-2,0) is on the line as well:

y = 2x+b

0 = 2(-2)+b

b=4

Choice D

Answers

Sorry! OK. I'll make this quick.  Formula: A= A+B+C+D
A= 134 cm2
B= 170 cm2
C= 202cm2
D= 238 cm2
So, just add them altogether.
A= 744 cm (But I don't know what the exponent would be. Sorry!) I think that is how it would be. Its been a while since of done Area, though. Sorry about not knowing the exponent. And sorry if this isn't acurate.

An angle that measures 82° is bisected. What is the measure of each resulting angle?A)38° and 44° B)40° and 42° C)41° and 41° D)42° and 42°

Answers

The measure of each resulting angle is 41° and 41°. Option C is correct.

Given that,
An angle that measures 82° is bisected, To determine is the measure of each resulting angle.

What is an angle bisector?

An angle bisector is the line segment that bisects the angle into two equal halves.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
bisecting of angle measure 82°.
= 82 / 2
= 41°  

Thus, the measure of each resulting angle is 41° and 41°. Option C is correct.

#SPJ2

When an angle is bisected, it is cut exactly in half.

82/2 = 41.

The resulting two angles will each be 41 degrees.

Your answer is C.

Simplify this expression. Explain step-by-step the process.

-12÷3•(-8+(-4)²–6)+2

Answers

well so you have to go with pemdas. p parenthesis, e exponets,m multipication, d division, a add, s subtract. let start with the parenthesis which is 8 plus negative four to the secondpower minus 6. so negative 4 to the second power is equal to positive sixteen because negative time negative is equal to positive. so 8 plus sixteen is 24-6 is 18. negative 12 divided by 3 is negative 4.so negative 4 time 18 is negative 72 plus 2 is negative 70.the answer is negative 70
Using PEMDAS to answer this, the steps are:
Parenthesis first, so (-8+(-4)^2-6)= 2 
You now have -12/3 (2)+2 
Next is multiplication, so 3(2)= 6
Now you have -12/6 +2
Next is division, so -12/6= -2
Now you have -2+2
Add them together to get the answer of 0
Hope this helped!

A fair number cube is rolled what is the probability that a number greater then 4 is rolled

Answers

Answer: 1/3

Step-by-step explanation: Probability is the likelihood that an event will happen.

So to find the probability of rolling a die and the number that appears will be greater than 4, it's important to understand that there are only 2 numbers that are greater than 4 on a die. The two numbers are 5 and 6.

We can find the probability of an event using the following ratio.

Number of favorable outcomes/total number of outcomes.

In this case, since we're asked to find the probability of landing on 5 or 6, the favorable outcomes are rolling a 5 and 6. Since there are two numbers greater than 4 on a dice, the number of favorable outcomes will be 2.

The total number of outcomes is all the numbers on the dice which is 6.

Now we have the fraction 2/6. Since 2/6 is not in lowest terms, we divide the numerator and denominator by 2 and we get 1/3.

1/3 is also equivalent to 33.3333333% which means it's unlikely to roll a 5 or 6.

2/6

5 and 6 out of the 6 numbers
