A parabola has a vertex at (–5, 0) and passes through the point (–3, 1). Which of the following is the equation of this parabola in the form y=a(x-h)^2+k?

Answers

Answer:

y = 1/4(x + 5)^2

Step-by-step explanation:

Using the given equation form;

(h,k) represents the vertex of the parablola

To get the value of a, we use the given point

So we have;

1 = a(-3 + 5)^2 + 0

1 = a(2)^2

4a = 1

a = 1/4

so we have the equation as;

y = 1/4(x+5)^2 + 0

y = 1/4(x + 5)^2

f (x) = x2 – 5, what is f(1)

Answers

Answer:

-3

Step-by-step explanation:

f(x)=x2-5  f(1)

f(1)= (1)2 -5

2-5

-3

ANSWER: -3

WHY: since 1 is x we replace the x which creates f(1) = 1•2-5
Then we multiply 1•2 which gives us 2 so now f(1)=2-5
Lastly we subtract 2-5 which results in -3 making f(1)= -3

compounded semi-annually
The solution is

Answers

Answer:

15 Years or 14.5 Years

Step-by-step explanation:

According to the Question,

Given That, Cora invests $1000 at Rate of 5% Per Annum. Interest is compounded semi-annually, After What time her money to get double.We Know, the formula A=P(1+r/n)^(nt)    (where r=0.05 , p=1000 , A=2000 , n=2)

Put the Given value in Formula, We get

2000 = 1000 (1 + 0.05/2) ^ 2t

2 = (1+0.025)^2t

2 = (1.025)^2t   ⇔ 1.025^30 = 2.0975 ≈ 2

Thus, 2t = 30 ⇒ t = 15 Years

OR

2 = (1.025)^2t   ⇔ 1.025^29 = 2.0464 ≈ 2

Thus, 2t = 29 ⇒ t = 14.5 Years

179 (4 + 4)

Answers

The answer would be 4000 plus 2800 plus 360 plus 400 plus 280 plus 36

Answer:

Step-by-step explanation:

(179 * 40) + (179 * 4) = 179 *(40 + 4) = 179 * 44

YES

(100 * 4) + 70*4 + 9*4 =  4 * ( 100 +70 + 9) = 4 * 179

No

4000 + 2800 + 360 + 280 +36 = 7876 = 179 *44

YES

(100 *44) + (70*44) + (9*44) = 44 * (100 + 70 +9) = 44 * 179

YES

Set up an en equation and use it to solve for x

Answers

Answer:

x = 30

Step-by-step explanation:

The 2 angles lie on a straight line and sum to 180° , then

x - 3 + 153 = 180

x + 150 = 180 ( subtract 150 from both sides )

x = 30

Answer:

x = 30

Step-by-step explanation:

180° = total

153° = part

180° - 153° = 27°

Then use the equation to find the value of x

(x - 3) = 27

(x + 3) = +3       Add 3 to both sides!

x = 30

A 28 foot ladder leans up against a building and reaches the base of a window that is 20 feet high. How far is the base of the ladder from the base of the building? Round your answer to the nearest whole foot

A 16 feet

B 20 feet

C 24 feet

D 34 feet

Answers

Answer:

20 feet

Step-by-step explanation:

The distance between base of the ladder from the base of the building is given by option B) 20 feet.

Use the Pythagorean theorem to solve this problem.

The Pythagorean theorem states that in a right-angled triangle,

The square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

Length of the ladder = 28 foot

Here, the ladder forms the hypotenuse, and the height of the window (20 feet)

And the distance from the base of the ladder to the base of the building (let's call it x feet) are the other two sides.

So, we have:

Ladder² = Height² + Distance²

28² = 20² + x²

Now, let's solve for x:

x² = 28²- 20²

x² = 784 - 400

x² = 384

Now, take the square root of both sides to find x:

x = √384

x ≈ 19.6 feet

Rounding to the nearest whole foot, the distance from the base of the ladder to the base of the building is 20 feet.

Therefore, the distance between base of the ladder and building is equal to option B) 20 feet.

-2.5x-.5

[tex]y=\frac{2}{3}x-1[/tex]

draw the dotted line (3/7)x-3 and shade below it

Step-by-step explanation:

First, we need the slope

Use the slope formula:

[tex]\frac{Y_2-Y_1}{X_2-x_1}=\frac{2-(-8)}{-1-3}=\frac{10}{-4}=-2.5[/tex]

so we have

y= -2.5x+b

Solve for b by plugging in coordiantes

-8= -2.5(3)+b

-8= -7.5+b

b= -.5

Put it together and get -2.5x-.5

2.)

A line is parallel to another line if they have the same slope (and different y intercepts)

So in the formula y=mx+b we knowe that m= 2/3

Now it's just a matter of solving for B

plug in the required coordinate to do this

-1=(2/3)*0+b

-1= b

Put it all together to get

[tex]y=\frac{2}{3}x-1[/tex]

3.)

put this into slope intercept form

3x-7y>21

3x-21 > 7y

(3/7)x-3 >y

To graph this just draw a dotted line with the equation (3/7)x-3 and shade everything below it (use de_smos if you're stuck)

the meal costs $52.95 for 5 people. Jenna ordered a dessert for $2.50. if Jenna deducts this amount from the total how much will each of the other people pay for their meal

Answers

Subtract the dessert from the total:

52.95 - 2.50 = 50.45

Now divide that by the number of people:

50.45/5 = 10.09

Each person would pay $10.09

She would pay 10.09 + 2.50 = 12.59

52.95/5 = 10.59
2.50/5 = .50
All the others beside her will pay $10.09 for their meal.

A pair of equations is shown below:

y = 6x − 4
y = 5x − 3

Part A: In your own words, explain how you can solve the pair of equations graphically. Write the slope and y-intercept for each equation that you will plot on the graph to solve the equations. (6 points)

Part B: What is the solution to the pair of equations? (4 points)

Answers

Answer:

A) To plot equations in point-slope form, pick one and let x = 0, then solve for y (or -4). That gives you point 1 (0,-4). Then let y = 0 and solve for x (or 2/3). That gives you a second point (2/3,0). Plot the two points and draw the line. Repeat for the second equation (points are (0,-3) and (3/5,0)). Where the lines cross is the solution for both equations.

B) point (1,2) fits both equations.

Step-by-step explanation:

Or solve by brute force...

The solution is where the same X,Y point fits both equations, or Y1 = Y2 and X1 = X2. So the equations in point-slope form (already in point-slope form) equal to each other, solve for X and plug that back into either of the equations to find Y.

6X - 4 = 5X -3

X = 1  so

y = 6X - 4

Y = 6 - 4

Y = 2

If the equation of a line is 2y+3x=3, what is the y intercept of the line?​

Answers

Answer:

3/2

Step-by-step explanation:

2y+3x=3

This represents a linear equation and the format for a linear equation is

y = mx+b

m = slope

b= y-intercept

we have to subtract 3x from both sides to make this the y=mx+b form

2y=-3x+3

and divide both sides by 2

y = (-3x+3)/2

3/2 or 1.5 is the y-intercept

the constant of a linear equation (or 3) is the y-intercept, if there is no constant then the y-intercept is 0

Answer:

1.5

Step-by-step explanation:

2y+3x=3

Convert to y=mx+b form...

y=mx+b

y(output)

x(input)

x(slope/growth)

b(y int/starting point)

Steps for converting to y=mx+b form:

-subtract 3x from both sides of equal sign

-divide by 2 on both sides

2y+3x = 32y = -3x+3y = -1.5+1.5

y = -1.5+1.5

so 1.5 is y int.
