Because when you put it in the calculator it will show if the solution is right. For example,
f(x) = a(x-h)^2 +k
Vertex is (2,-4)
Plug in the vertex and Pick a coordinate to test
I pick (0,-3)
f(x) = a(0-2)^2 -4= -3

Write a linear function f with the values f(−1)=5 and f(3)=4.
Answers
Answer:
1 Expert Answer When they say f(0) = -5 they mean the point (0, -5) is on the line. When they say f(3) = 4 they mean the point (3, 4) is on the line. In y = mx + b form, we would have f(x) = 3x - 5.
Step-by-step explanation:
The function is to be determined from the given points.
The linear function is [tex]f(x)=-\dfrac{1}{4}x+\dfrac{19}{4}[/tex]
The given values are
[tex]f(-1)=5[/tex]
[tex]f(3)=4[/tex]
The ordered pairs are [tex](-1,5),(3,4)[/tex]
The equation of the line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)\\\Rightarrow y-5=\dfrac{4-5}{3-(-1)}(x-(-1))\\\Rightarrow y-5=-\dfrac{1}{4}(x+1)\\\Rightarrow y-5=-\dfrac{1}{4}x-\dfrac{1}{4}\\\Rightarrow y=-\dfrac{1}{4}x-\dfrac{1}{4}+5\\\Rightarrow y=-\dfrac{1}{4}x+\dfrac{19}{4}[/tex]

Write the following equation from the verbal description given
and then solve the equation.
"Two and three-fourths times the sum of twelve times a
number c and negative seven is equal to thirty-five and three-
fourths."
Answers
The equation for the given verbal descrption "two and three-fourths times the sum of twelve times a number c and negative seven is equal to thirty-five and three-fourths." is [tex]2\frac{3}{4}[/tex]( 12c -7) = [tex]35 \frac{3}{4}[/tex] and its solution is c = 5/6.
According to the given question.
We have a verbal description for a equation i.e. "two and three-fourths times the sum of twelve times a number c and negative seven is equal to thirty-five and three-fourths."
So, the equation for the above verbal description is given by
[tex]2\frac{3}{4}[/tex]( 12c -7) = [tex]35 \frac{3}{4}[/tex]
Therefore, the solution for the above equation is given by
11/4(12c - 7) = 143/4
⇒ 11(12c - 7) = 143 (multiply both the sides by 4)
⇒ 132c - 77 = 143
⇒ 132c = 143 + 77
⇒ 132c = 220
⇒ c = 220/132
⇒ c = 110/66
⇒ c = 55/66
⇒ c = 5/6
Hence, the equation for the given verbal descrption "two and three-fourths times the sum of twelve times a number c and negative seven is equal to thirty-five and three-fourths." is [tex]2\frac{3}{4}[/tex]( 12c -7) = [tex]35 \frac{3}{4}[/tex] and its solution is c = 5/6.

Jeremy has heard a lot of people in the club talking about tackling a 950-foot rock formation. Jeremy has set a limit that they won't climb anything that takes longer than 7 hours, so they have enough time to travel to and from the place. Will it be possible to climb a 950-foot rock formation within Jeremy's time constraint? Explain why or why not.
Answers
Answer:
The answer is "no".
Step-by-step explanation:
Please find the image file of the question in the attachment.
In the given question, it will take approximately 2-3 min to climb 1 step taller. It's an estimate of 7.92 hours, if you split 950 to 2, it is the period it would take you to go out in minutes when we turn 475 mins into minutes. As we see it will take them an extra 92 mins for 950 feet to ascend. They can achieve it by ascending this at an average rate of 135.7 ft/h.
Answer:
No, the amount of minutes to climb up 1 foot of the height would be around 2-3 minutes. If you divide 950 with 2, you get 475 which would estimate to 7.92 hours. So as we see they would need an extra 55.2 minutes to climb the full 950 feet.

What is an orthogonal matrix?
A matrix is said to be orthogonal if its antipode is also its transpose and if its relationship to the inner product is established. A real square matrix with orthonormal vectors in its columns and rows is known as an orthogonal matrix or orthonormal matrix in direct algebra. Where QT is the transpose of Q and I is the identity matrix is one system to put this into words. However, the matrix is said to be orthogonal, If the transpose of a square matrix with real figures or values is equal to the inverse matrix of the matrix. In other words, an identity matrix will always be affected by the product of a square orthogonal matrix and its transpose.Here, the determinant of T,
|T| = cos²∅ + sin²∅
= 1
Now, its cofactors,
[tex]T_{11}[/tex] = cos ∅
[tex]T_{12[/tex] = sin ∅
[tex]T_{21[/tex]= -sin ∅
[tex]T_{22[/tex] = cos ∅

Gabby is an aspiring country artist. She has a record contract that pays her a base rate of $200 a month and an additional $12 for each album sold. Last month she earned a total of $644. Identify the y-intercept in the equation.
Answers
Answer:
From the formula above, you see that your slope would be the $12.
Step-by-step explanation:
So, from this problem the base rate is the y-intercept because it is fixed. The slope of the is the additional fee because it's changing by the number of albums sold. Below is the equation that should have been created using the slope intercept formula.
220 + 12x = 644
You will need the slope intercept form, y = mx + b

The meal total was $50. If we leave a 20% tip, then what will the meal cost us total. (Hint: meal total plus tip = overall total: tip = meal x %(in decimal form)
Answers
Answer:
Total cost of meal is $60
Step-by-step explanation:
The cost of meal = $50
Tip = 20%
We need to find total cost of meal
First find 20% of 50 to get the amount given for tip
[tex]20\% \:of\: 50\\=\frac{20}{100}\times 50\\=10[/tex]
So, tip given is $10
Total cost of meal = 50+10 = $60
So, total cost of meal is $60
in general, if lim x->a m(x) does not exist and lim x->a n(x) does not exist, is it true that lim x->a [m(x) n(x)] does not exist?
Answers
The claim is untrue because, in the case of discrete functions, the absence of either function limit does not imply that the limit product of those two functions will also not exist.
What exactly are limit functions?When a variable approaches its limit from the right, the function's right-hand limit is the value that approaches. When a variable approaches its limit from the left, the function's left-hand limit is the value that approaches. The limit of a function in mathematics is a key idea in calculus and analysis regarding the behavior of that function close to a specific input. Below are formal definitions that were initially developed in the early 19th century. Informally, a function f gives each input x an output f(x). The limit of a constant multiplied by a function is the same as the limit of the function multiplied by the constant. A product's limit is equal to the product of its limits. A quotient's limit is the same as the quotient of its limits. A constant function's limit is the same as the constant.

We need to find f(x+1)
We are given:
[tex]g(x) - f(x) = -2x + 5\:and\:g(x) = 5x -3[/tex]
First we need to find f(x)
By putting value of g(x) into g(x)-f(x)
[tex]g(x) - f(x) = -2x + 5\\\Put\:value\:of\:g(x) = 5x -3\\5x-3-f(x)=-2x+5\\-f(x)=-2x+5-5x+3\\-f(x)=-2x-5x+5+3\\-f(x)=-7x+8\\f(x)=-(-7x+8)\\f(x)=7x-8\\[/tex]
We have, [tex]f(x)=7x-8[/tex]
Now finding f(x+1) by putting x=x+1
[tex]f(x)=7x-8\\Put\:x=x+1\\f(x+1)=7(x+1)-8\\f(x+1)=7x+7-8\\f(x+1)=7x-1[/tex]
So, [tex]\mathbf{ f(x+1)=7x-1}[/tex]
