HELP ME!!!!!! h(x) = -(x + 2)2 + 8 what is the axis of Symmetry
Answer:
The vertical line [tex]x = -2[/tex] is the axis of symmetry of [tex]y = -(x + 2)^{2} + 8[/tex].
Step-by-step explanation:
For the graph of a quadratic function, the axis of symmetry is the vertical line that goes through the vertex of this function.
In general, if the vertex of a quadratic function is at [tex](x_{0},\, y_{0})[/tex], the vertex form equation of this function would be [tex]y = a\, (x - x_{0})^{2} + y_{0}[/tex] for some non-zero constant [tex]a[/tex] ([tex]a \ne 0[/tex].)
Rewrite the quadratic equation in this question [tex]y = -(x + 2)^{2} + 8[/tex] to match the vertex form:
[tex]y = -(x + 2)^{2} + 8[/tex].
[tex]y = (-1)\, (x - (-2))^{2} + 8[/tex].
Thus:
[tex]a = (-1)[/tex].[tex]x_{0} = (-2)[/tex].[tex]y_{0} = 8[/tex].Hence, the vertex of this parabola would be at [tex](-2,\, 8)[/tex].
Again, the axis of symmetry of this graph would be a vertical line that goes through this vertex. The [tex]x[/tex]-coordinate of this vertical line would be [tex](-2)[/tex]. The equation of this vertical line would be [tex]x = (-2)[/tex].
Hence, the axis of symmetry of this quadratic function would be [tex]x = (-2)[/tex].

the width of a rectangle measures (8c-5)(8c−5) centimeters, and its length measures (2c 10)(2c 10) centimeters. which expression represents the perimeter, in centimeters, of the rectangle?
The expression that represents the perimeter of the rectangle is [tex]$\boxed{20c + 10}$[/tex] centimeters.
We are given that;
Width= (8c-5)(8c−5) centimeters
Length= (2c 10)(2c 10) centimeters
Now,
The perimeter of a rectangle is given by the formula:
P = 2l + 2w
where l is the length and w is the width.
[tex]$w = (8c-5)\ cm$[/tex]
and
[tex]$l = (2c+10)\ cm$[/tex]
Substituting these values into the formula for the perimeter, we get:
[tex]$P = 2l + 2w = 2(2c+10) + 2(8c-5) = 4c + 20 + 16c - 10 = \boxed{20c + 10}\ cm$[/tex]
Therefore, by rectangle the answer will be [tex]$\boxed{20c + 10}$[/tex].

It takes Santa a total distance of 1800 miles to cover a portion of his
Texas route, he does this in 3 hours, how fast is Santa moving? *
2400 mph
600 mph
350 mph
150 mph
please help!! hurry
Answer:
the answer is 600mph
Step-by-step explanation:
because 1800miles/3 hours=600mph
Answer:
600 mph
Step-by-step explanation:
In order to find the answer you must solve using this formula:
S=D/T
Where S is speed, D is distance, and T is time
You have time and distance, so you have to plug those into the formula:
S=1800/3
Then all you have to do is divide 1800/3 and get 600 for speed.
Find the distance between points P(8, 2) and Q(3, 8) to the nearest tenth.

the department of education wishes to estimate the proportion of all college students who have a job off-campus. it surveyed 1600 randomly selected students; 451 had such jobs. the population of interest to the department of education is:
The population of interest to the department of education will be all college students.
A population is a large group of individuals that have some common feature by the researcher's point of interest.
Here the Department of Education wishes to estimate the proportion of all college students who have a job off-campus.
Proportion: A proportion is an equation in which two ratios are set equal to each other. If there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls. 0.25 are boys (by dividing 1 by 4).
So , he needs data of all students to compute the exact proportion.
But instead of that he surveyed 1600 randomly selected students which determine the sample.
Sample just gives the estimate of the parameter.
Hence, the population of interest to the Department of education is " All college students" .

Enter the formula to find the surface area of a prism involving area of the Base and Perimeter of the base
Answer:
p=3+4+5=12
Step-by-step explanation:
Answer:
96 inches2 or 352 cm2
Step-by-step explanation:
-Okay so, we know that The lateral surface area of a prism is the sum of the areas of its lateral faces. And The total surface area of a prism is the sum of the areas of its lateral faces and its two bases. Then Usually, if "right" or "oblique" is not mentioned, you can assume the prism is a right prism. The general formula for the lateral surface area of a right prism is L.S.A.=ph where p represents the perimeter of the base and h represents the height of the prism.

What is an mathematical expression?
Expression in mathematics is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Here, it is given that :
Ella works two part-time jobs, one before school and one after school. Before school, she earns $11.25/hour, and after school "a" she earns $11..75/hour and She works twice as many hours after school that is :
a = 2b ......(1)
also, 11.25a + 11.75b = 278....(2)
now, solving for a and b :
11.25a + 11.75b = 278
11.25(2b) + 11.75b = 278
b = 278/34.25
b ≈ 8 hours
Now, the value of a will be 2b = 16 hours
Therefore, the Ella works 16 hours after school and 8 hours before school.

Lin has two small baking pans, each shaped like a rectangular prism. For each question, explain or show your reasoning.
a. Lin lines the bottom of her first pan with aluminum foil. The area of the rectangular piece of foil is 1114 square inches. Its length is 412 inches. What is the width of the foil?
b. Lin's second pan has a length of 83 inches, a width of 154 inches, and the height of 32 inches. What is the volume of the second pan?
Answer:
2 1/2
Step-by-step explanation:
( 11 1/4 ) / ( 4 1/2 ) = 2 1/2
( 2 1/2 ) = 5/2
The width of the pan is 2.70 inches.
The volume of the pan is 409,024 inches³
A rectangular prism is a polyhedron with six faces and twelve edges. It is also known as a cuboid.
The width of the foil can be determined by dividing the area by the length.
Width = area / length
1114 / 412 = 2.70 inches
Volume of the pan =length x width x height
83 x 154 x 32 = 409,024 inches³

5 pounds of bananas for $1.97 for 3 pounds of bananas for $1.05 which is better to buy
Answer:
3 pounds for $1.05 is better since it is 35 cents a pound as opposed to 39 cents a pound for the other product.Step-by-step explanation:
We need to find the unit rate. This found by dividing the price by the number of bananas so we get the price for 1 pound of bananas.
$1.97/5 = $0.39
$1.05/3 = $0.35
3 pounds for $1.05 is better since it is 35 cents a pound as opposed to 39 cents a pound for the other product.There are 4 baskets that store 16 bathroom towels. Consider the number of bathroom towels per basket

First write the first equation in system A. x - y = 3
Multiply the second equation in system A by 4 and add to the first equation in system A to get:
2x = 10
x = 10/2 = 5
Put x = 5 in x - y = 3
5 - y = 3
