Find the value of a and b when x=10

a = 5x (squared) ÷ 2

b = 2x (squared) (x-5) ÷ 10x

​

Answer:

252

Step-by-step explanation:

Answer:

Step-by-step explanation:

9/2 is the slope. Slope defines how steep is the straight line.

Slope =  change in y ÷ change in x

In this model, 9 refers to the vertical distance between two points

and 2 refers to  the horizontal distance between two points.

9/2 is a positive slope. It indicates that if 'x' increases, y also increase.

Answer:

EF = 36

Step-by-step explanation:

On a rhombus, all sides are equal because its a parallelogram so,

EF = FG

we first have to find what x equals so . . .

let's plug in the numbers

4x - 20 = 2x + 8

Now we combine like terms

we add 20 to both sides

so now it would be

4x = 2x +28

Now we subtract 2x from both sides because we want x by itself

this would equal

2x = 28

now we divide two from both sides this equals

x = 14

now we insert the numbers in the equation

4 x 14 - 20 = 36

Answer:

1. 4y-12

2. c

For #1 you distribute the 4 to the y and the 3. 4 times 3 equals 12.

For #2 you factor out the 3 and you get 3(5x+1)

Answer:

4y-12

Step-by-step explanation:

Multiply the outside number by the numbers in the bracket.

Example:4×y=4y Because y=1

4×3=12

2.Answer C

3(5x+1)

3×5x=15x

3×1=1

Which is equivalent to 3(5x+3)

The requried range of the radio station is given as 1256 square miles.

The area of the circle is given by the pie times square of the radius.
A = πr², where r is the radius of the circle.

Here,
A small radio station can broadcast in a circular range with a radius of 20 miles.
The range is given by the area of the circle with given radius,
Area of the circle = πr²
Area of the circle = 3.14 × 20²
area of the circle = 1256 square miles

Thus, the requried range of the radio station is given as 1256 square miles.

Answer:

2=41     1=49      3=49

Step-by-step explanation:

Angle 2 = 41 because it is directly across the given angle.

Angles 1 and 3 are equal, and the total number of degrees in the rombus are 180.

41+41=82

180-82=98

98 / 2 = 49

Angles and 3 both equal 49

Answer:

2=41°(Alternate Interior angles)

1=41°(diagonal of rhombus bisects the interior angles)

3=49°(180-82/2)

Step-by-step explanation:

Answer:  1.9

Step-by-step explanation:

You want to multiply 9x10 which is 90.

Then you want to add 44+pi

now pi can be shown as 3.14 or 22 over 7

in this case you want to add 44 + 3.14 which gives you 47.14

now you want to divide 90/47.14 which gives you 1.90920661858 or in short

Answer:

19.65 left

Step-by-step explanation:

The total amount that he has is 3 * 12 =                   36 dollars.

From this he buys a CD for                          15.00

There is a 9% tax on 15 dollars 15*9/100 =   1.35

Amount spent =                                                         16.35

Amount left                                                               19.65

Paul saves $3 each week for 12 weeks.

3 × 12 = $36

He buys the CD for $15

The tax is 9% out of $15.

15 × 9/100 = $1.35

In total he spent $16.35

To find the money he has left we take the total amount of money he had before he bought anything and subtract it with the money he spent.

36 - 16.35 = $19.65

Answer:

4

Step-by-step explanation:

cos(-π) = -1 [in radians]

3-(-1) = 4

There are many ways to answer this but, I'll try to explain it.

You can see that you are computing a limit when some n approaches negative PI. You get to substitute negative PI instead of n and compute cos(-pi) which is -1.

Then compute f(x) - (-1) = 3 - (-1) = 4 which is a result.

The way you can imagine cos(-pi) or cos(-90deg) is by dragging point in a unit circle beneath x-axis and to the bottom y-axis (-90 angle), the y coordinate tells you the cosine value at (-90) and because you have dragged the point on the unit down to y-axis the value is -1.

Answer:

3x - y = -3

Step-by-step explanation:

divide everything by 4, the greatest common factor. That's all you need to do.

Answer: y=3x+3

Step-by-step explanation:

12x -4y= -12

subtract 12x from both sides

-4y= -12x-12

Divide everything by -4 to make y positive and alone

y=3x+3

The secend part of the question is B. 2∧15x∧15

Answer:

t = 1 s

Step-by-step explanation:

The function models the height of the ball after t seconds is given by :

[tex]h=32t - 16t^2[/tex]

We need to find how many seconds does it take for the ball to reach its maximum height.

For maximum height put dh/dt = 0

[tex]\dfrac{dh}{dt}=\dfrac{d}{dt}(32t - 16t^2)\\=32-32t[/tex]

So,

32-32t = 0

t = 1

So, it will take 1 second to reach its maximum height.
