Answer:

D! See explanation below!

Step-by-step explanation:

D is absolutely correct!

And I'll explain why:

The area of the trapezoid is (lower base + upper base) times (height) divide 2

So:[tex](4+7)(8)/2\\=11(4)\\=44 (cm)^{2}[/tex]

The area of the Triangle is (Base)(Height)/2

So:[tex](6)(10)/2\\=30(cm)^{2}[/tex]

Well, 44 is larger than 30, so the answer's D!!!

Hoped I helped. (P.S. I love math!!!)

Answer: A parallelogram is a quadrilateral with both pairs of opposite sides parallel.

Step-by-step explanation: If a quadrilateral has 2 sets of opposite sides congruent, then it is a parallelogram.

Answer:

1. 2:5

2. 110 (the total degree of a triangle is 180 so it would be 40+30+x=180)

3. 37 (It's a right angle, 90 degrees so it would be 90-53=x)

Answer:

which is $160

Step-by-step explanation:

2,000 of 8%

= 160

2,000 divided by 8%

In the next 6 years she will pay only: "R$ 160,00"

Nos próximos 6 anos ela ppagará apenas: "R$ 160,00"

[tex]8[/tex]%[tex]de[/tex][tex]\frac{8}{100} .2000 = \frac{8.2000}{100} = \frac{8.20}{1} = \frac{160}{1} = 160[/tex]

Answer:

f{0) is greater than g(0) and f(2) is greater than g(2).

Step-by-step explanation:

f{0) is greater than g(0) = f(0)=8  and g(0)=2

f(2) is greater than g(2) = f(2)=8 and g(2)= -4

The two statements that are correct are f(0) is greater than g(0), and f(2) is greater than g(2).

The general equation of a parabola is given as,

[tex]y=a(x-h)^2+k[/tex]

where (h,k) is the coordinate of the vertex of the parabola.

The equation of the parabola with vertex (1,9) can be written as,

[tex]y=a(x-h)^2+k\\\\y=a(x-1)^2+9[/tex]

Now, the value of a can be found by putting one zero of the parabola,

[tex]y=a(4-1)^2+9\\\\0=a(3)^2+9\\\\-9=a(3)^2\\\\-9=a9\\\\a=-1[/tex]

Thus, the equation of the parabola can be written as y=-(x-1)²+9.

A.) The value of the two functions when the value of x is -2 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(-2)=-(-2-1)^2+9\\\\f(-2)=0[/tex]

[tex]g(x) = -3x + 2\\\\g(-2) = -3(-2) + 2\\\\g(-2)=8[/tex]

Therefore, f(-2) is less than g(-2).

B.) The value of the two functions when the value of x is -1 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(-1)=-(-1-1)^2+9\\\\f(-2)=5[/tex]

[tex]g(x) = -3x + 2\\\\g(-1) = -3(-1) + 2\\\\g(-1)=5[/tex]

Therefore, f(-1) is equal to g(-1).

C.) The value of the two functions when the value of x is 0 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(0)=-(0-1)^2+9\\\\f(0)=8[/tex]

[tex]g(x) = -3x + 2\\\\g(0) = -3(0) + 2\\\\g(0)=2[/tex]

Therefore, f(0) is greater than g(0).

D.) The value of the two functions when the value of x is 1 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(1)=-(1-1)^2+9\\\\f(1)=9[/tex]

[tex]g(x) = -3x + 2\\\\g(1) = -3(1) + 2\\\\g(1)=1[/tex]

Therefore, f(1) is greater than g(1).

E.) The value of the two functions when the value of x is 2 can be written as,

[tex]f(x)=-(x-1)^2+9\\\\f(2)=-(2-1)^2+9\\\\f(2)=8[/tex]

[tex]g(x) = -3x + 2\\\\g(2) = -3(2) + 2\\\\g(2)=-4[/tex]

Therefore, f(2) is greater than g(2).

Thus, the two statements that are correct are f(0) is greater than g(0), and f(2) is greater than g(2).

Answer:

The difference between the two is that in a dependent event an action will affect the ultimate outcome, but in an independent event an action won't affect the ultimate outcome. A way to tell is if the total number of the "item" at hand will be affected by the action the question is saying. In the case of the example given, that is a dependent event because the total of marbles you started with is changed due to you not replacing the one you first took. Therefore the probability is now different.

Answer: its A

Step-by-step explanation:

A. y = -x^2 - 1

B. y = x^2 + 3

C. y = 1/2x

D. y = -3x - 5

There are two equation of the system

(1) The perimeter

    2(w + l) = p

    2(w + l) = 86

(2) The length and the width

     2w = l + 2

From the second equation

2w = l + 2

l + 2 = 2w

l = 2w - 2

Subtitute l with 2w - 2 in the first equation to find the width

2(w + l) = 86

2(w + 2w - 2) = 86

2(3w - 2) = 86

6w - 4 = 86

6w = 90

w = 15

Now, find the length by subtituting w with 15

l = 2w - 2

l = 2(15) - 2

l = 30 - 2

l = 28

The dimension of the rectangle

length = 28 cm

width = 15 cm

Answer:

x=60.9

Step-by-step explanation:

Let x represent the number

x - 54%x = 28

x - 0.54x = 28

0.46x = 28

Divide both sides by 0.46

x = 28/0.46

x = 60.86

x = 60.9

Answer:

they each hold 1 1/3 litters of cola

Step-by-step explanation:

Because if there is 2 2/3 liters of cola

then you either divide it by 2

or you can look at it and see what would add evenly to make that number

in this case it would be 1 1/3

1 1/3 +1 1/3= 2 2/3

Answer:

She spent $10.12

Step-by-step explanation:

8.60*.07 = .602, round that to .60

8.60 + .60 = 9.2

9.2*.10 = .92

9.2 + .92 = 10.12

Answer:

$10.12

Step-by-step explanation:

Do $8.60 + $8.60(7%) = $9.20

Then $9.20 + $9.20(10%) = $10.12

Answer:

{4, 13}

Step-by-step explanation:

Represent the integers by I and J.  Then I + J = -17 and I*J = 52.

Let's solve this system using substitution.  Solve the first equation for I as follows:  

I + J = -17 becomes I = -J - 17

Substitute -J -17 for   I   in the second equation:

(-J - 17)*J = 52

Performing the indicated multiplication, we get:

-J^2 - 17J - 52 = 0

Let's solve this using the quadratic formula.  The quadratic coefficients here are {-1, -17, -52}, and so the discriminant, b^2 - 4ac, is

(-17)^2 - 4(-1)(-52), or 289 - 208, or 81.  This result is positive, so we know that the quadratic equation has two real, unequal roots.  They are:

      17 ± √81         17 ± 9

J =  --------------- = ---------------

         2(-1)                  -2

Evaluating this last result, we get J = (17 + 9)/2, or J = 13, and

J = (17 - 9)/2 = 8/2, or J = 4
