Answer:

a= -1

b= 3

c= -7

The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.

Step-by-step explanation:

Answer:

A. t= 4.1

B. No because t = 4.1 and if you do 6.5 divided by 1.5 then you get 4.3 and that won't work.

Answer:

77%

Step-by-step explanation:

23 divided by 30 is 0.766666, which percent-wise is rounded to 77% :)

Answer:

77%

Step-by-step explanation:

30 was 100%

23 is  x%

x=23*100/30 = 76.666.. rounded to 77%

Answer:

1.3%

Answer:

measure of angle p=

94

Step-by-step explanation:

ok 5 sided polygon= 540

so put all of those equal to 540

need to find x first

540=132+(4x-10)+(5x-11)+128+(4x+2)

simplify and combine like terms

x=23

now plug in for angle p

(4(23)+2)

94

As we know point slope form ,

(Y- Y1) = m (X- X1)

As given data ,

m = -2/5

(X1,Y1) =  (5, -12)

X1= 5 , Y1=  -12

putt in the above equation these values, we get

Y-(-12) = (-2/5) ( X-5)

Y+12=(-2/5)X+2

taking LCM we get

Y  = ((-2)X-50)/5

Answer:

Step-by-step explanation:

I'm assuming you're not doing the pre-calculus version of this equation where your angle is in radians. So we'll do the Geometry version which looks like this:

[tex]AL=\frac{\theta}{360}*2\pi r[/tex]

Our angle is 30 and our radius is 4, so we fill in accordingly:

[tex]AL=\frac{30}{360}*2(3.1415)(4)[/tex] (this is if you multiply in pi. We'll find the answer in terms of pi as well).

AL = [tex]\frac{1}{12}*25.132[/tex] and

AL = 2.09433 inches

In terms of pi, the answer would be

AL = [tex]\frac{2}{3}\pi[/tex] inches

Answer:

The point estimate is 366/2380

Step-by-step explanation:

Here. we want to find a point estimate for the number of golfers that are left-handed

To get this, we simply divide the number of left-handed golfers by the number of golfers surveyed

Mathematically, this will be 366/2380

Answer:

16/625

Step-by-step explanation:

Step one:

sample space

A bag contains

5 cherry,

8 orange,

2 grape,

7 bubblegum, and

3 apple  lollipops.

sample size= 5+8+2+7+3= 25

Required:

The probability of choosing grape for your first lollipop

and orange for your second?

1. The probability of choosing the grapes lollipops

=2/25

2. the probability of choosing the orange  lollipops----Note in the second choice the sample size will reduce because the first choice was done with out a replacement

=8/24

The total is

2/25*8/25= 16/625

Diving question: 0 - 35.25 + -8.5 = -43.75 below sea level

Baking question: insolvable by lack of information.

2. Answer/Step-by-step explanation:

A money decrease of $60.50 (or -60.50 increase and change)

? - 45 - 30.15 + 14.65 = -60.50

Since we are finding the change it is best to replace the question mark with 0 so that it is easier to solve.

0 - 45 = -45

-45 - 30.15 = -75.25

-75.25 + 14.65 = -60.50

Answer:0

Step-by-step explanation:0x0=0

Answer:

(21, 8)

(3, 2)

(-15, -4)

Step-by-step explanation:

First we need to create the equation in y=mx +b form.

(m) is slope [rise/run]

(b) is y intercept

The line crosses the y axis at (0,1) so that's our (b) and to find slope we will find a point where ethe line crosses a point, I'll use (0, 1) and see how many it has to go to reach the next point. In this case it has to go up 1, and right 3.

Our slope is 1/3.

y=1/3x+1.

Now we can start applying the given points.

(21, 8)

8=1/3(21)+1

8=7+1

8=8.

(21, 8) is a solution.

(3, 2)

2=1/3(3)+1

2=1+1

2=2

(3, 2) is a solution.

(-15, -4)

-4=1/3(-15)+1

-4=-5+1

-4=-4

(-15, -4) is a solution.

(12, 9)

9=1/3(12)+1

9=4+1

9=5

(12, 9) is not a solution.

(-6, 1)

1=1/3(-6)+1

1=-2+1

1=-1

(-6, 1) is not a solution.
