What is the area of the semi circle whose radius is 8cm

Answer:

1)  6(3x-2)

2) 24(x+2)

3) 9(5x−9) or 9(5x+9) if you meant to put addition.

4)8x+15

Answer: 1. 26

Answer:

C?

Step-by-step explanation:

A) Jared makes x of a goodie bag per hour. How many

can he make in y of an hour?

B) Jared makes x of a goodie bag per hour. How many

can he make in y of an hour?

C) Jared has x of an hour left to finish making goodie  bags. It takes him y of an hour to make each goodie  bag. How many goodie bags can he make?

D) id k

Quotient is the answer to a division problem, so we need to find a problem that needs to divide x and y to find the answer. It isn't A or B, since they are asking for y, not the quotient. I have no idea what D is. C makes sense, so C might be the answer.

It tells us how much time he has(x), and how long it takes him to make 1 bag(y), and we need to find the answer, which is the quotient.

So C is the answer.

Answer:

c

Step-by-step explanation:

The key features needed are the slopes and y-intercepts. If the slope and the y-intercept are the same then there are infinite amounts of intersections. If the slope is the same and the y-intercept is different then they will never intercept. Of the slope and the y-intercept are different, then they will intersect at one point.

Step-by-step explanation:

Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

2 −  − 12 = 0

= 1

= -1

= − 12

Answer:

The first option:

Down 5, left pi/2.

Step-by-step explanation:

Let's define the translations in a general way.

Horizontal shift.

For a function f(x), a horizontal shift of N units is written as:

g(x) = f(x + N)

if N is positive, the shift is to the left.

if N is negative, the shift is to the right.

Vertical shift.

For a function f(x), a horizontal shift of N units is written as:

g(x) = f(x) + N

If N is positive, the shift is upwards.

If N is negative, the shift is downwards.

In this case, we have the function:

f(x) = 6*Sin(2*x + π) - 5

Where the original function was something like:

h(x) = 6*sin(2*x)

Here we can already see the vertical shift is of minus 5 units, so the shift is 5 units down.

then we get:

f(x) = h(x) - 5 =  6*sin(2*x) - 5

Now we can apply a shift  to the left of  π/2 units, so we get:

f(x) = h( x + π/2) - 5 =  6*sin(2*(x +π/2) ) - 5

f(x) =  6*sin(2*x +π ) - 5

Then the correct option is:

Down 5, left pi over 2

Answer:

A, C

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

the ∠A is adjacent (adj) to  AB and opposite (Opp) of BC and AB is the hypotenuse (Hyp) of the triangle

which one of the above trig functions fits that?

sin(Ф) = BC / AC   is sin(Ф)= Opp / Hyp , so choice A) works

cos(Ф) = BC / AC  is not cos(Ф) = Opp / Hyp  so choice B) does not work

cos(Ф) = BA / AC  is cos(Ф) = Adj / Hyp  so choice C)  works

AC / BC is just a ratio   it's not the angle , so D) doesn't work

Answer:

The factors are 3 and -9

Step-by-step explanation:

The given trinomial is [tex]x^2-6x-27[/tex].

We need to find two factors. We know that,

3(9) = 27

So,

[tex]x^2-6x-27[/tex] can be written as :

[tex]x^2+3x-9x-27[/tex] as two factors add up to get -6 and multiply to get -27.

Hence, the factors are 3 and -9.

Answer:

The area is multiplied by 4

Step-by-step explanation:

The area of a circle is directly proportional to its square radius so if the radius is increased by x, the area will be increased by x ^ 2

Step-by-step explanation:

Answer:

|GH| = 5,7 cm

Step-by-step explanation:

To know |GH|, you first need to find the length of |GD|.

We can calculate |GD| by;

cosG = |GC| / |GD|

<=> |GD| = |GC| / cosG

 => |GD| = 3,9 cm/ 0,62 = 6,33 cm

We now can easily calculate |GH| with the sinus of angle D;

sinD = |GH| / |GD|

<=> |GH| = sinD.|GD|

 => |GH| = 0,899.6,33 cm = 5,694 cm => 5,7 cm

Step-by-step explanation:

Answer:

40 shots total.

Step-by-step explanation:

First, change the percentage to a decimal:

80% = 80/100 = 0.80

Next, divide the amount of baskets made (32) with the decimal gotten to get the  total amount of shots:

32/0.80 = 40

Brandon took a total of 40 shots.

Check. Divide 32 (shots made) with the 40 (total shots in all):

32/40 = 0.8 = 80%.

Answer:

x=-1, y=1

Step-by-step explanation:

Answer:

( -1, 1 )

Step-by-step explanation:

To solve, graph the equations and find the point of intersection.

when graphed these equations intersect at (-1, 1)

To double-check and make sure it's correct, plug in a solve.

x = -1

y = 1

y = 2(-1) + 3

1 = 2(-1) + 3

1 = -2 + 3

1 = 1

y = x + 2

1 = (-1) + 2

1 = 1

Answer: x2 + 12x

Step-by-step explanation:

Answer:

cos(A) = 12/13

Step-by-step explanation:

There are several ways to remember trigonometric functions, but my personal favorite is:

SOH - CAH - TOA

Where Sin(angle) = Opposite/Hypotenuse

Cos(angle) = Adjacent/Hypotenuse

and Tan(angle) = Opposite/Adjacent

The opposite is the side of a triangle that does not form part of the angle. E.g. for angle A the opposite is 5, for angle B the opposite is 12.

The hypotenuse is the longest side of the triangle, or the opposite in relation to the right angle (signified here by the little red box in the bottom left).

The adjacent is the side that isn't the hypotenuse, but is still next to a given angle. E.g. the adjacent for angle A is 12, and the adjacent for angle B is 5.

The cosine of angle A is the adjacent of angle A divided by the hypotenuse. The side adjacent to A is 12, and the hypotenuse is 13. Therefore, the cosine of angle A is 12/13.

86 would be the answer

Step-by-step explanation:

Answer: 86 minutes

Step-by-step explanation:

To find the mean of something, you always add up the values and then divide by the amount.

So, in total there are 430 minutes because (170+150+45+30+35=430)

Answer:

11 1/5

Step-by-step explanation:

Answer:

(3,2)

Step-by-step explanation:

5x+2y= 19

4x - 3y = 6

I will use elimination

Multiply the first equation by 4

20x +8y = 76

Multiply the second equation by -5

-20x +15y = -30

Add them together to eliminate x

20x +8y = 76

-20x +15y = -30

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

       23y = 46

Divide by 23

23y/23 = 46/23

y =2

Now find x

5x+2y =19

Substitute y=2

5x+2(2) =19

5x+4 = 19

Subtract 4 from each side

5x +4-4 =19-4

5x= 15

Divide by 5

5x/5 = 15/5

x=3

The solution is
