Step-by-step explanation:

Never capitalize the seasons

Answer:

[tex] {3y}^{3} - 12y \\ = 3y( {y}^{2} - 4) \\ = 3y( {y}^{2} - {2}^{2} ) \\ = 3y(y - 2)(y + 2) \\ = 3y(y + 2)(y - 2)[/tex]

a^2-b^2=(a+b)(a-b)

a=y b=2

3y(y+2)(y-2)

Answer:

$840

Step-by-step explanation:

Given data

Principal = $3000

Rate= 7%

Time= 4 years

The expression for the simple interest is

SI= PRT/100

substitute

SI= 3000*7*4/100

SI= 30*7*4

SI= $840

Hence the interest is $840

Answer:

1.52

Step-by-step explanation:

38 decreased by 4% = 36.48

Absolute change (actual difference):

36.48 - 38 = - 1.52

Answer:

odd; even; even; odd

Step-by-step explanation:

The answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.

It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We know when the graph is symmetric about the origin it is an off function.

When the graph is symmetric about the y axis it is an even function.

When f(-x) = f(x) it is an even function

When f(-x) = -f(x) it is an odd function.

Thus, the answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.

Answer:

the answer is −4x+10y−6z

Step-by-step explanation:

(−2x+5y−3z)2

Use the distributive property to multiply −2x+5y−3z by 2.

−4x+10y−6z

Answer:

(-2x+5y-3z)2

-2x*2+5y*2-3z*2

-4x+10y-6x

Answer:

Let the scores on the first two test be x

Let score for third test be 14 exceeds second( or first) = x + 14

Total = 233

x + x + (x + 14) = 233

3x + 14 = 233

3x = 219

x = 73

Score of the third test = x + 14 = 73 + 14 = 87

Therefore, the scores are 73, 73, 87

Answer:

B,48.2

Step-by-step explanation:

To solve this we need to use SOH, CAH, TOA

we have the adjacent and hypotonouse so it's easiest to use CAH

let theta (angle) = x

cos(x)=4/6

to cancel the cos mulitply both sides by cos^-1 (2nd --> cos)

x=48.1896851

which rounds to 48.2

Answer:

56

Step-by-step explanation:

Zoe and Hannah shared tips in the ratio

3:7

Last week Zoe received $24

Hence the amount received by Hannah can be calculated as follows

3/7= 24/x

168= 3x

x= 168/3

= 56

Hence Hannah received €56

Answer:

75ft^2

Step-by-step explanation:

A = pi*r^2

The circle already gives the diameter and the diameter is two times the radius, so if you were to divide the diameter by two, you would get 5.

Knowing the radius is 5 and seeing how they replaced pi with 3 we can set up the equation.

3*(5)^2 = A

Simplify

3*25

Multiply

Area=75ft^2

Answer:

B

Step-by-step explanation:

Because its going down so its negative.

Plus, its 5 down four to the right or 5/4=1.25

So the answer is -1.25

Answer:

x= -4, y= -20

Step-by-step explanation:

y= 16x+44

(y= -x²+8x+28) * (-1)

multiply both sides by -1  

y= 16x+44

-y= x²-8x-28

add the equations to eliminate y

y-y= x²+16x-8x+44-28

0= x² +8x +16 this is the same with (x+4)²=0 so x= -4

go back to the first equation and substitute x with -4 and solve for y

y= 16*(-4) +44 = -64+44 = -20

Answer:

The interval is [4,7]

Step-by-step explanation:

The rate of change is given by

f(x2) - f(x1)

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

x2 -x1

We want the rate of change to be 56

f(x2) - f(x1)

-------------------  = 56

x2 -x1

We also know that the x2 is 7  so f(x2) = 192

192 - f(x1)

-------------------  = 56

7 -x1

192 - f(x1) = 56( 7 -x1)

192 - f(x1) = 392 -56x1

Now we need to pick points from the table and see where it is true

(6,96)

192 - 96 = 392 -56*6

96=56  False

( 5,28)

192 - 28 = 392 -56*5

164=112  False

(4,24)

192 - 24 = 392 -56*4

168=168  True

The interval is [4,7]

Answer:

8.77 or 8.80

Step-by-step explanation:

Answer: tanA=3/4

Step-by-step explanation: If  cosA=4/5 then

sinA=√(1−cos2A)  {Because sin^2A+cos^2A=1}

=>sinA=√(1−16/25)

=>sinA=√(9/25)

=>sinA=3/5

Now as  tanA=sinA/cosA

=>tanA=3/5×5/4  {Because 1/cosA=5/4}

=>tanA=3/4
