Answer:

Area is 10.5

Step-by-step explanation:

We can use the trapezoid formula of

[tex]A = \frac{a+b}{2}h[/tex]

A = (2 + 5) / 2 * 3 = 3.5 * 3 = 10.5

or break it into a rectangle and a triangle (natural split by y axis).

A = 2 * 3 + 3 * 3 / 2 = 6 + 9 / 2 = 6 + 4.5 = 10.5

Answer:

10.5 units²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = OS = 3 , b₁ = OC = 5 , b₂ = SK = 2 , then

A = [tex]\frac{1}{2}[/tex] × 3 × (5 + 2) = 1.5 × 7 = 10.5 units²

Answer:

Start at the y-intercept (0, -4.5) and then use rise over run (Up 3 and right 4)

Step-by-step explanation:

y - y1 = m(x - x1)

y + 3 = 3/4(x - 2)

y + 3 = 3/4x - 3/2

y = 3/4x - 9/2

Step-by-step explanation:

Option B is correct.

Answer:

x=-3, y=4. (-3, 4). B)

Step-by-step explanation:

7x+2y=-13

-3x-8y=-23

-------------------

4(7x+2y)=4(-13)

-3x-8y=-23

---------------------

28x+8y=-52

-3x-8y=-23

-------------------

25x=-75

x=-75/25

x=-3

7(-3)+2y=-13

-21+2y=-13

2y=-13-(-21)

2y=-13+21

2y=8

y=8/2

Answer:

A: 4/5

Step-by-step explanation:

The equation for proportionality is y = kx, where k is the constant of proportionality. That is what you're looking for in this question.

So in y = 4/5x, 4/5 is the constant of proportionality/unit rate for the proportional relationship.

The 4/5 is the constant of proportionality/unit rate for the proportional relationship.

We have given that,

the unit rate for the proportional relationship is represented by the equation y=4/5x.

We have to determine the unit rate

The equation for proportionality is y = kx, where k is the constant of proportionality.

So in y = 4/5x,

The 4/5 is the constant of proportionality/unit rate for the proportional relationship.

Answer:

y=2x-2

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(8-4)/(5-3)

m=4/2

m=2

y-y1=m(x-x1)

y-4=2(x-3)

y=2x-6+4

y=2x-2

Answer: $1,467.80

Step-by-step explanation:

The formula for the future value given annual compounding is:

= Amount * ( 1 + rate) ^ number of years

The amount after 3 years at 5.5% is therefore:

= 1,250 * ( 1 + 5.5%)³

= 1,250 * 1.174241375

= $1,467.80

sin θ cos C

Step-by-step explanation:

Suppose,  θ=30°

Suppose,

     sin θ cos θ=1

 ⇒sin30°cos30°=1

 ⇒[tex]\frac{1}{2}[/tex]×[tex]\frac{\sqrt{3\\} }{2}[/tex]=1

Answer:

co interior angle plz take my and

Answer:

1) Alternate exterior

2) alternate interior

3) consecutive interior angles

Alright so here’s a trick

Alternate already means different sides so look for that.

Interior angles are all the angles inside the two parllel lines.

Exterior angles are all angles out side the two parralel lines.

No matter what if its alternative interior or exterior, it should make a perfect

“/“ or back slash.

Consecutive is on the same side.

Corresponing is also on the same side but it has 1 exterior and 1 interior

Answer:29

Step-by-step explanation:

d[AB]=|45-16|=29

A number line is the representation of numbers in real order.

The difference between the consecutive numbers in a number line is always positive.

The length AB is 29.

AB = 29 is our answer.

It is the representation of numbers in real order.

The difference between the consecutive numbers in a number line is always positive.

We have,

A is at point 16.

B is at point 45.

Now,

The distance between A and B.

= B - A

= 45 - 16

= 29

Thus,

The length AB is 29.

AB = 29 is our answer.
