Answer:
C
Step-by-step explanation:
A parabola is set of all points in a plane which are an equal distance away from a given point and given line. The point is called the focus of the parabola and the line is called the directrix.
Focus is the name of the point that you use to define a parabola
What is Parabola?A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped
A parabola is a symmetrical U-shaped curve that can be defined as the set of all points that are equidistant to a fixed point (called the focus) and a fixed line (called the directrix).
The vertex is the point where the parabola changes direction and is located halfway between the focus and the directrix.
The center is a term used to refer to the midpoint of the line segment connecting the two foci of an ellipse or hyperbola, and is not relevant to a parabola.
Hence, Focus is the name of the point that you use to define a parabola

Jenna saves $2,500 per year in an account that earns 10% interest per year, compounded annually. Jenna will have saved in 30 years. Her account balance is a result of Jenna’s .
Answer:
$43,625
Step-by-step explanation:
Hello,
The question is a direct application of compound interest and we'll approach this question using the formula of compound interest.
A = P(1 + r/n)^nt
A = compound interest
P = principal
r = rate of the interest
n = number of times compounded
t = time interval for the money to be compounded.
Data;
A = ?
P = $2,500
r = 10% = 0.1
n = 1 (since it's compounded annually)
T = 30 years
A = 2,500 [1 + (0.1 / 1)]^(1 × 30)
A = 2,500 × [1 + 0.1]³⁰
A = 2,500 × 1.1³⁰
A = 2,500 × 17.45
A = $43,625
In 30 years, Jenna would've saved $43,625

Parallelogram L M N O is shown. Angle M is (3 x minus 55) degrees, angle N is (5 y) degrees, and angle O is (2 x) degrees. In parallelogram LMNO, what are the values of x and y? x = 11, y = 14 x = 11, y = 25 x = 55, y = 14 x = 55, y = 25
Answer:
The correct option is:
x=55 , y = 14
Step-by-step explanation:
We know about the following features of a parallelogram:
Opposite sides are parallelOpposite side have equal lengthOpposite angles are equalSum of all angles is 360°For the parallelogram LMNO, <L and <N are opposite angles, <M and <O are opposite angles.
Are opposite angles are equal.
<M = <O
3x - 55 = 2x
3x - 2x = 55
x = 55
So
<M = 3x - 55 = 110°
<O = 2x = 110°
We know that the sum of angles is 360°
<L + <M + <N + <O = 360°
<L + <N + 110° + 110° = 360°
As <L and <N are opposite, both are equal. hence <L = <M = 5y
5y + 5y + 220° = 360°
10y + 220° = 360°
y = 14
Answer:
x = 55, y = 14
Step-by-step explain
it is X = 55, y = 14

Identify the type of chart described and complete the sentence.
A
chart shows open and close prices and highs and lows, but over a long time period it can also show pricing
Reset
Next
Answer:
The chart type described is the OHLC chart.
Step-by-step explanation:
An OHLC chart is a kind of bar-chart that displays open, high, low, and closing prices for each period. OHLC charts are beneficial since they demonstrates the four major data values over a period, with the closing price being reflected as the most significant by traders.
The chart type is valuable since it can represent increasing or decreasing movement. When the open and close are far-apart it represents strong movement, and when the open and close are close together it represents wavering or weak movement. The high and low displays the full price range of the period, useful in evaluating instability.
Thus, the chart type described is the OHLC chart.

A building block is made by taking a 6 cm by 4 cm by 2 cm block and removing four cubes from the center of the block. The volume of the final block is 44 cm3.
A rectangular prism with a length of 6 centimeters, width of 4 centimeters, and height of 2 centimeters. 4 blocks are removed from the block with dimensions 6 by 4 by 2 centimeters.
What is the length of one side of one cube that was removed?
1 cm
1.5 cm
2 cm
2.5 cm
Answer:
(A)1 cm
Step-by-step explanation:
Volume of the Prism before the cubes were removed[tex]=6 X 4 X 2 = 48$ cm^3[/tex]
Volume of the Prism after the 4 cubes were removed[tex]=44$ cm^3[/tex]

Standard Form: ax+by=c
For most convenience start with slope-intercept form: y=mx+b
1. -1 = -1(3)+b - solve for b
b=2
y= -1x+2 (slope-intercept form)

(SAT Prep) In the given figure, the reflex angle ∠DOB has measure of 3.5y while the measure of ∠AOD is y. Find the measure of the non-reflex ∠DOB in degrees.
Answer:
252°
Step-by-step explanation:
In the figure attached, the diagram is shown. There, we can see that
∠DOB = ∠AOD + ∠AOC + ∠COB
Replacing with the equivalences: ∠DOB has a measure of 3.5y, the measure of ∠AOD is y, and ∠AOC + ∠COB measure 180°, we get:
3.5y = y + 180°
3.5y - y = 180°
2.5y = 180°
y = 180°/2.5
y = 72°
Therefore, ∠DOB = 3.5*72° = 252°
Answer:
108 degrees
Step-by-step explanation:
m∠DOB=m∠AOD+m∠AOC+m∠COB And then we substitute, m∠DOB=3.5y, m∠AOD=y, m∠AOC+m∠COB=180 degrees. So the equation will then be 3.5y=y+180 degrees
y= 72
m∠DOB=3.5 x 72 m∠DOB=252 degrees, this is the reflex angle.
360-252=108 degrees, the non-reflex m∠DOB= 108 degrees

How many solutions does the equation have 4p + 1 = 49 - 7
Answer:
so one solution
Step-by-step explanation:
4p+1=49 - 7
minus 1 to -7= -8
4p= 49-8
4p=41, divided by 4 and you'll get a decimal, 10.25
Answer:
1 solution if solving for p.
Step-by-step explanation:
If solving for p:
4p+1=49-7
4p+1=42
Subtract 1 from both sides
4p=41
Divide both sides by 4
p=10.25
There is only one solution, 10.25
But I've seen this question on a Quizizz and the answer was no solutions. I don't think that's correct but... might be because the question didn't ask to solve for p.

Because all consecutive angles in a parallelogram are supplementary, m∠SVU = 180 - 57 = 123°.
Answer:
Step-by-step explanation:
In a parallelogram, sum of adjacent angles is 180
∠TSV + ∠SVU = 180
57 + ∠SVU = 180
∠SVU = 180 - 57
∠SVU = 123°

calculate the area of a circle with a diameter of 8 feet
Answer: 50.27
Step-by-step explanation:
Area = pi r^2
= pi x 16
Answer:
50.265 [tex]ft^{2}[/tex]
Step-by-step explanation:
The formula of the area of a circle is [tex]\pi r^{2}[/tex] and the diameter is double the amount as the radius, so the radius would be 4 feet. 4 squared is 16. Multiply that by pi to get your answer, 50.265[tex]ft^{2}[/tex].
Solve by taking the square root of both sides 3(x-1)^2-162=0
a. x = -1 - 3 sqrt 6 or -1 + 3 sqrt 6
b. x = 1 - 3 sqrt 6 or -1 + 3 sqrt 6
c. x = -1 - 3 sqrt 6 or 1 + 3 sqrt 6
d. x = 1 - 6 sqrt 6 or 1 + 6 sqrt 6
Answer:
see explanation
Step-by-step explanation:
Given
3(x - 1)² - 162 = 0 ( add 162 to both sides )
3(x - 1)² = 162 ( divide both sides by 3 )
(x - 1)² = 54 ( take the square root of both sides )
x - 1 = ± [tex]\sqrt{54}[/tex] = ± 3[tex]\sqrt{6}[/tex] ( add 1 to both sides )
x = 1 ± 3[tex]\sqrt{6}[/tex]
x = 1 - 3[tex]\sqrt{6}[/tex] or x = 1 + 3[tex]\sqrt{6}[/tex]
