Answer:

degree 3

Step-by-step explanation:

The degree of a polynomial is determined by the largest exponent of the variable within the polynomial.

Given

t³ + 5t² - 3t + 2

The leading term t³ has exponent 3 , then

The polynomial is degree 3

Answer:

no(double check my math!!)

Step-by-step explanation:

on the second step it should be 4 not 16 bc 10-6=4

2x-8+3x+2=4x+10+3x-6

5x-6=7x+4

-6=2x+4

-10=2x

-5=x

Answer:

In this equation, y = 2x - 5, it is already in that form and so the cumber in front of the x is the slope (2) and the constant number is the y-intercept (-5) - it's negative because of the minus sign in front of the number. So, the slope is 2 and the y-intercept is -5.

Answer:

The answer is C. 12m

Step-by-step explanation:

Given a=35 and c=37,

b = 12

∠α = 71.075° = 71°4'31" = 1.2405 rad

∠β = 18.925° = 18°55'29" = 0.3303 rad

h = 11.35135

area = 210

perimeter = 84

inradius = 5

circumradius = 18.5

Answer:

9. a. 6

9. b. 2; 1

9. c. 3.14; 1.57

9. d. 7.57

10. 3106.86

Step-by-step explanation:

9.  a.  The rectangle has a length of 3 and a width of 2, so that means its area has to be 6.

9. b. The semi-circle's diameter is 2, because it is the same width as the rectangle, and finding the radius, means that you need to cut the diameter in half, so the radius of the circle is 1.

9. c. To find the full circle, we must use the formula (pi)(r)^2. So we have 3.14(1), which is just equal to pi. but since we need half the circle, we must divide the number by 2, to get the answer 1.57...

9. d. Finally we need to add up all the values together, from a. we know that the rectangle has an area of 6, and from b and c, we know the semi-circle has an area of 1.57, so we add those two numbers together we get 7.57.

10. We can do the exact same thing as number nine, which means the rectangle is 30*70=2100, The radius of the circle is 15 (30/2), the area of the circle (and since there are 2 semi circles, we don't need to divide by 2) we get 706.86, now all thats left is to add the numbers together to get the number 2806.86.

Step 1

4n-9=2(5+2n)  Equation/Question

Step 2

4n-9=2(5+2n)  Remove parenthesis

4n-9=4n+10

Step 3

4n-9=4n+10  Subtract 4n to sides

-9=10

Step 4

-9=10  Add 9

Answer:

Step-by-step explanation:

Times 332 by 7

Answer:

7. A=48

8.B=30

9. C=188

10. D=18

11. X=32

12.Y=40

Step-by-step explanation:

Answer:

7. [tex]a=48[/tex]

8. [tex]b=30[/tex]

9. [tex]c = 188[/tex]

10. [tex]d = 18[/tex]

11. [tex]x = 32[/tex]

12. [tex]y = 40[/tex]

Step-by-step explanation:

Let's do something called cross-multiplication. It's exactly what it sounds like, we multiply the top number with the denominator across the multiplication.

[tex]\frac{33}{a} = \frac{11}{16}[/tex]

[tex]11 a = 33(16)[/tex]

[tex]11a = 528[/tex]

Now we can simplify.

[tex]a=48[/tex]

So we got the answer for the first one. We can keep doing the same thing for the others.
