Answer:

[tex]y=-1(x-2)^2+1[/tex]

Step-by-step explanation:

The parabola has the vertex (2, 1) and goes through the point (4, -3).

We will use the vertex form, given by:

[tex]f(x)=a(x-h)^2+k[/tex]

Where (h, k) is the vertex and a is the leading coefficient.

Line 1)

So, by substitution:

[tex]\text{Vertex}=(h,k)=(2,1)\Rightarrow y=a(x-2)^2+1[/tex]

Lines 2-4)

Since (4, -3) is a point, y = -3 when x = 4:

[tex]-3=a(4-2)^2+1[/tex]

[tex]-3=a(2)^2+1[/tex]

[tex]-4=4a\Rightarrow a = -1[/tex]

Line 5)

By substitution, we acquire our equation*:

Nick bought a pair of jeans that originally cost $74.98. The jeans were markdown 25%. How much did the jeans cost after the discount?

Answers

74.98-0.25=18.745
74.98-18.75=56.23

The cost is 56.23 after the discount.

$56.23

The jeans cost $56.24 after the 25% discount.

What is a percentage?

The percentage means the required value out of 100.

It is calculated by dividing the required value by the total value and multiplying it by 100.

The percentage change is also calculated using the same method.

In percentage change, we find the difference between the values given.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

To find the price of the jeans after the 25% discount,

We need to multiply the original price by 0.75 (which is 100% - 25%).

So,

Discounted price = $74.98 x 0.75 = $56.24

Therefore,

The jeans cost $56.24 after the 25% discount.

What is the fraction?

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Given that, Mariana fed 1/6 of a box of crackers to the birds outside her house. She shared the rest with Nina.

Fraction of crackers Nina got = 1 -1/6

= (6-1)/6

= 5/6

Therefore, the fraction of crackers Nina got is 5/6.

Let M be the number of shots it takes Jeremiah to successfully make his first three-point shot. Assume that the results of each shot are independent. Find the probability that Jeremiah's first successful shot occurs on his 3rd attempt. You may round your answer to the nearest hundredth. P(M=3)=

Answers

Answer: .14

Step-by-step explanation: Khan Academy

Answer:

0.14

Step-by-step explanation:

First off, please read clearly.

This problem is asking for the probability that (M = 3).

The correct answer for this P(M = 3) problem is 0.14 through Khan Academy.

Even when you solve it, it is 0.14. The equation would be zero point twenty-five multiplied by parenthesis one minus zero point twenty-five closed parenthesis to the power of two. Written out the equation would be the following:

0.25x(1-0.25)^2

*** DO NOT MIX THIS UP WITH A VERY SIMILAR PROBLEM TO THIS. ***

There is a problem using this same Jeremiah situation but it asks for P(M < 4).

If you want the answer for P(M < 4) it is 0.58 so

P(M < 4) = 0.58

And another Jeremiah problem that asks for P(M > 6).

If you want the answer for P(M > 6) it is 0.18 so

P(M > 6) = 0.18

solve the inequality c + 6 < -20

Answers

Answer:

The answer is c<−26

Step-by-step explanation:

The solution to the given inequality c + 6 < -20 is c < -26, which is shown in the attached number line.

To solve the inequality c + 6 < -20, we need to isolate the variable c.

First, we can subtract 6 from both sides of the inequality:

c + 6 - 6 < -20 - 6

This simplifies to:

c < -26

Therefore, the solution to the inequality is that c is less than -26. In other words, any value of c that is smaller than -26 will satisfy the inequality.

To represent this on a number line, we can mark a point at -26 and shade all the values to the left of it, including -26, to indicate that they satisfy the inequality.
