What is the distance between the points (7, 8) and (-8, 0) on a coordinate grid?
Answer:
17 units
Step-by-step explanation:
Moving from (-8, 0) to (7, 8), we see x changing by 15 units from -8 to 7 and y changing by 8 units from 0 to 8.
Regard 15 units as the horizontal leg of a right triangle and 8 units as the vertical leg. We use the Pythagorean Theorem to determine the length of the hypotenuse of this right triangle and interpret the result as the distance between the points:
d = √(15² + 8²) = √289 = 17
The distance between the given points is 17 units.

PLEASE HELP!! find the value of c
Step-by-step explanation:
step 1. so you want to convert a quadratic (ax^2 + bx + c) into a perfect square
step 2. therefore c is half of b then squared
step 3. (26/2)^2 = 169
step 4. (-22/2)^2 = 121
step 5. (-13/2)^2 = (-6.5)^2 = 169/4 = 42.25.

Answer:
1/ 2
Step-by-step explanation:
Given that :
Fraction left over = 3/8
Fraction of leftover ate = 3/4
Amount of the whole cake Norma have at lunch :
Fraction left over ÷ fraction of left over ate
3/8 ÷ 3/4
3/8 * 4/3
(3*4) / (8*3)
12 / 24
1/2
1/2 of the whole cake

Which quadratic function in vertex form has a vertex at (−5 , −4) and passes through the point (−2 , −1)?
y=−13(x+5)^2−4
y=−13(x−5)^2+4
y=13(x−5)^2−4
y=13(x+5)^2−4
Answer:
y = 1/3(x + 5)^2 - 4
Step-by-step explanation:
The general vertex form is;
y = a(x-h)^2 + k
From the question, (h,k) are the coordinates of the vertex which is (-5,-4)
So we have
y = a(x + 5)^2 -4
So we need to get the leading coefficient
Simply substitute the point it passes through
x = -2 and y = -1
-1 = a(-2 + 5)^2 - 4
-1 = a(3)^2 -4
-1 = 9a -4
9a = 4-1
9a = 3
a = 3/9
a = 1/3
So the equation is;
y = 1/3(x + 5)^2 - 4

a) No
I b) Yes
Answer:
A
Step-by-step explanation:
The measure of the angles of a triangle = 180
70 + 80 + 45
150 + 45
195 degrees
195 > 180
So, A) No
The total surface area of a cube is 294cm^2.
Work out the volume of the cube.
Answer:
343 cm ^3
Step-by-step explanation:
A cube has 6 squares of equal sizes. 294/6 = 49
The area of one square is 49
Since the area is the length squared, the square root of 49 is 7.
Volume of a cube is area times height. 49 x 7 = 343 cm^3
