Find the equation of the quadratic function given the vertex and a point on the parabola.

v= (3,0), p=(1,4) ​

Answers

Answer 1

Answer:

y = x² - 6x + 9

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k ) = (3, 0 ) , then

y = a(x - 3)² + 0

To find a substitute (1, 4) into the equation

4 = a(1 - 3)² = a(- 2)² = 4a ( divide both sides by 4 )

1 = a

y = (x - 3)² = x² - 6x + 9

128 in exponential form

Answers

Answer:

2^12

Step-by-step explanation:

I know that 128 is 32 x 4, so 128 is 2^5 x 2 x 2 = 2^7. Thus,

128 x 32 = 2^5 x 2^7.

The last step is to realize that if two factors have the same base (in this case, both bases are 2), then you can add the exponents:

2^5 x 2^7 = 2^5+7= 2^12.

And that is in exponential form. So the final answer is

128 x 32 = 2^12

Answer:

[tex]128 \: \: is \: \: 32 \times 4, \\ \\ so 128 is  {2}^{5}   \times 2 \times 2 = {2}^{7} . \\ \\ Thus, 128 \times 32 = {2}^{5} \times {2}^{7} .[/tex]

Exercise #6: Demarco is trying to determine how many pennies he has without having to count
them. He first weighs 20 pennies and finds they have a total weight of 54 grams. He then weighs
all the pennies and finds they weigh a total of 918 grams.
(a) Determine how much a single penny
weighs, i.e. the grams per penny.
(b) Use your answer from (a) to determine
how many pennies Demarco has.

Answers

Step-by-step explanation:

20 pennies weigh 54 grams.

what is the weight of a single penny ?

well, 1/20 of the weight of the 20 pennies.

so,

54/20 = 27/10 = 2.7 grams

all his pennies weigh 918 grams.

how many pennies are there ?

as many as the times the weight of a single penny fit into the total weight.

so,

918 / 2.7 = 9180/27 = 340

he has 340 pennies.

Answer:

y = -1x - 2/2

Step-by-step explanation:

Slope is -1

B = 2/-2

Answer:

y = x - 4

Step-by-Step Explanation:

Perpendicular lines have slopes that are negative reciprocals—multiplying their slopes result in -1.

Given the slope of a line m = -1, then it means that the slope of the other line must be 1 (because multiplying the slope of line 1  (m1 = -1), and the slope of the other line (m2 = 1) results in: -1 × 1 = -1).

Therefore, given the slope of line 2 (m2 = 1), and the point (2, -2), we could plug these values into the slope-intercept form and solve for the y-intercept (b):

y = mx + b

-2 = 1(2) + b

-2 = 2 + b

Subtract 2 from both sides to solve for b:

-2 - 2 = 2 - 2 + b

-4 = b

Therefore, the y-intercept (b) = -4.

Hence, the equation of the perpendicular line is: y = x - 4

Answer:

y = 2x + 5

Step-by-step explanation:

Finding the slope:

[tex]\frac{y2-y1}{x2-x1}\\[/tex]

= (1-(-3))/(-2-(-4))

= (1+3)/(-2+4)

= 4/2

= 2

Slope: 2

Substituting the slope into the formula 'y=mx+c':

y = 2x+c

Substituting any point (in this case, (-2,1)):

1 = 2(-2) + c

1 = -4 + c

c = 1 + 4

c = 5

Hence,

y = 2x + 5

Answer: B

Explanation: Trust me

Isha, a super excited candy crush user, has increased her points by 75% percents in a week. shes at 14000 points now. how many points did Isha have on candy crush last week?

Answers

If she has increased by 75% in a week to get 14000 points then  we can say that 175% times a number has to equal 14,000 , where the number of points she had last week.

175% * x = 14000

1.75x =14000     Divide both sides by 1.75

x= 8000

So she had 8000 points last week.

Check:

175% * 8000= 14000

1.75 * 8000 = 14000

  14000 = 14000

Answer:

8,000 points

Step-by-step explanation:

x + 0.75x = 14,000 (the initial amount of points X plus 0.75x)

1.75x = 14000

x = 14000/1.75

x = 8,000

2. B.

Step-by-step explanation:

1. D. None of the above.

If the three angles of one triangle are congruent to the three angles of another triangle, the triangles are similar, but there is not enough information to prove they are congruent.

2.

The given information gives us a side and an adjacent angle of each triangle.

Since all choices involve sides, we need another pair of sides to use SAS. The angle must be included by the two sides.

We need sides DF and JH to be congruent.

By knowing that DH is congruent to JF, you add HF to both segments giving DF congruent to JH, and the triangles are congruent by SAS.
