In the equation y=a(x-h)^2+k, the "k" translates the parabola in what manner?
Answer:
k is the vertical shift
Step-by-step explanation:
y=a(x-h)^2+k
This gives the parabola in vertex form
(h,k) is the vertex where h is the x coordinate and k is the y coordinate
k is the vertical shift

What is the slope of y=17x
Answer:
17
Step-by-step explanation:
y=mx+b
m is always the slope. In this m is 17.
The slope is the tangent of the curve thus the slope of y = 17x will be 17.
What is the slope?A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
The slope could be positive or negative.
A linear equation or function is given as ;
y = mx + b
Here, m is the slope.
At x = 0 ⇒ y = b so it will be a y-intercept.
By comparing y = 17x
m = 17
Hence "The slope of the given line will be 17".

Sunil took a photo of his puppy. He wants to make different sizes of the photo the original photo is 2 inches by 3 inches can you use scale factors to solve the puzzle
Sunil can use scale factors to resize his photo. By multiplying the original dimensions by the scale factor, he can create photographs of different sizes. A scale factor greater than 1 will expand the photo, while a scale factor less than 1 will reduce its size.
Explanation:Yes, Sunil can definitely use scale factors to make different sizes of the photo. The original dimensions of the photo are 2 inches by 3 inches. A scale factor is a number which scales, or multiplies, some quantity. In this context, the quantity is Sunil's original photo. If Sunil wanted to double the size of his photo, for example, he would use a scale factor of 2. This would make his new photo 4 inches by 6 inches.
Similarly, if he wanted to make his photo smaller, he could use a scale factor of less than 1. For example, a scale factor of 0.5 would result in a photo that is 1 inch by 1.5 inches. This is because 2 inches (width) times 0.5 equals 1 inch, and 3 inches (height) times 0.5 equals 1.5 inches.

Given:
Funnel is in the shape of a cone.
Radius = 4 inches

To find:
a) The volume of the funnel
b) How many quarts of oil are in the funnel.
Solution:
Volume of cone:
[tex]$V=\frac{1}{3}\pi r^2 h[/tex]
[tex]$V=\frac{1}{3}\times 3.14 \times 4^2 \times 10[/tex]
[tex]$V=167.47[/tex] in³
The volume of the funnel is 167.47 in³.
1 qt ≈ 58 in³
To convert cubic inch to quarts divide by 58.

= 2.9 quarts
Therefore 2.9 quarts of oil are in the funnel.

Choose the most accurate statement based on the graph shown below.
A.) The graph is a good representation of the data.
B.) The graph is misleading because it uses 3-dimensional bars.
C.) The graph is misleading because the vertical range is too small creating the impression that differences are greater than they actually are.
Answer: A). The graph is a good representation of the data
Step-by-step explanation: The graph clearly represents that data, and it gets the point through. The graph is 3D, yet it clearly adds up to the lines therefore it is not misleading that way.
The vertical range seems fine to me, and I don't see how it being too small could create the impression that the distances are greater then they actually are.
I know its not B, because I did this question a couple minutes ago. Therefore there is nothing really misleading about this graph.

Evaluate the expression
[6+9 x (4-2)] ÷ 4+2
Answer:
8
Step-by-step explanation:
4-2=2
2x9=18
18+6=24
24/4=6
6+2=8
=8
To solve the expression [6+9 x (4-2)] ÷ 4+2, use the order of operations (PEMDAS), resulting in the answer 8.
The subject of this question is Mathematics and it involves the steps of evaluating the given mathematical expression, [6+9 x (4-2)] ÷ 4+2, which is a task typically encountered in middle school.
To solve this problem, we employ the Order of Operations, which can be remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Solve the expression in the parentheses: 4-2 = 2
Multiply 9 by the result from the parentheses: 9x2 = 18
Add 6 to the product: 6+18 = 24
Divide the sum by 4: 24 ÷ 4 = 6
Add 2: 6+2 = 8
Thus, [6+9x(4-2)] ÷ 4+2 equals 8.
