Answer:
y = -2x² + 8x + 10
Step-by-step explanation:
let's adjust the coordinates of vertex to a whole number: (2 , 17.75) to (2 , 18)
Quadratic equation: y = ax² + bx c or y = a(x-h)² + K (h,k) is the vertex
y = a (x-2)² + 18
a = (y-18) / (x-2)² = (16-18) / (1-2)² = -2 : calculate use point (1 , 16)
y = -2 (x-2)² + 18
y = -2x² +8x + 10

what is Arithmetic progression and geometric progression?
hope u have a great day!!
Answers
Answer:
Arithmetic progression is a series of numbers in which each one varies from the one before it by a constant quantity
Geometric progression is a non-zero number sequence in which each term after the first is found by multiplying the previous term by a fixed, non-zero number known as the common ratio.
Hope you have a good day as well! <3
Which of the following equations corresponds to the graph below
Answers
Answer:
d) y = -1/2 + 3
Step-by-step explanation:
Looking at the graph, we can use y = mx + b to find the equation. m is the slope and for slope, we go 1 unit down and 2 units to the right. b is the y variable and our b would be 3.
y = mx + b
y = -1/2x + 3

Cora uses 9.5 pints of blue paint and white paint to paint her bedroom walls. 2/5 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls
Answers
Answer:
5.7 pints
Step-by-step explanation:
Total pints of paint used = 9.5 pints
Fraction of blue paint used = 2/5 ; while the rest is white paint
Amount od blue paint used :
2/5 * 9.5 = 3.8 pints
Amount of white paint used :
Total pints - blue pints used
9.5 pints - 3.8 pints
= 5.7 pints of white paint.

Step-by-step explanation:
if x=19, 19x3 =57 and 57+123=180 and straight angle = 180 so A
Answer:
X=19
Step-by-step explanation:
123 and 3x are supplementary/they equal 180 added together.
Let's solve your equation step-by-step.
123+3x=180
Step 1: Simplify both sides of the equation.
3x+123=180
Step 2: Subtract 123 from both sides.
3x+123−123=180−123
3x=57
Step 3: Divide both sides by 3.
3x/3 = 57/3
x=19

The roots (zeros) of the function are (1, 0) and (3, 0). The point (2, 2) is the vertex, the maximum in this case.
The domain of any polynomial function is "all real numbers".
The range is y ≤ 2, not y < 2.

Answer:
35/37
Step-by-step explanation:
In this question, we are to calculate the ratio that represents the cosine of angle O
Firstly, please check the attachment for the diagram of the triangle.
Mathematically, the trigonometric term Cos means the ratio of the length of the adjacent to that of the hypotenuse
The hypotenuse is the longest length which is 37 which represents the length ON
The side adjacent to angle O is the side OP which is 35
Thus, the ratio representing the cosine of angle O is 35/37
What is the kinetic energy of a 4 kg cart pushed at a rate of 0.5 m/s?
A. 0.5J
B. 2J
C. 4J
D. 8J
Answers
Answer:
A. 0.5J
Step-by-step explanation:
[tex]K. E._{(cart)} = \frac{1}{2} m {v}^{2} \\ \\K. E._{(cart)} = \frac{1}{2} \times 4 \times (0.5)^{2} \\ \\ K. E._{(cart)} = 2 \times 0.25 \\ \\ K. E._{(cart)} = 0.5 \: J[/tex]
The kinetic energy of a 4 kg cart pushed at a rate of 0.5 m/s is 0.5 J.
Kinetic energy = 1 /2 mv²
where
m = mass
v = velocity
Therefore,
m = 4 kg
v = 0.5
Kinetic energy = 1 / 2 × 4 × 0.5²
kinetic energy = 1 / 2 × 4 × 0.25
kinetic energy = 1 / 2 × 1
kinetic energy = 1 /2 = 0.5 j

Answer:
Slope = -5/4
y-intercept = 7
Step-by-step explanation:
The equation is y = mx + b.
m is the slope, while b is the y-intercept.
Because -5/4 is where m would be in the equation, it is the slope.
7 is where b would be in the equation, so it is the y-intercept.

Davis has a thin box that is 5 inches wide. He wants to use the box to store markers that are 1/2 inch wide. If he lines up the markers side by side and uses the entire width of the box, how many markers can Davis fit in the box?
Answers
Answer:
10
Step-by-step explanation:
Given that :
Width of box, W = 5 inches
Width of marker to be stored in box = 1/2 inch
The number of 1/2 inch marker which can be stored in box is :
Width of box ÷ width of marker to be stored in box
5 inches ÷ 1/2 inches
5 / 0.5
= 10
Hence, Ten 1/2-inch width marker can be stored in the box
