A circle has area 36 cm². What is the diameter?
Answers
Answer:
6.77 cm
Explanation:
Given that the area of a circle = 36 cm²
We want to find the diameter of the circle.
The area of a circle of radius r is calculated using the formula:
[tex]A=\pi r^2[/tex]Substitute A=36 and π=3.14:
[tex]\begin{gathered} 36=3.14r^2 \\ \text{ Divide both sides by 3.14} \\ \frac{36}{3.14}=\frac{3.14r^2}{3.14} \\ r^2=\frac{36}{3.14} \\ \text{ Take the square root of both sides} \\ r=\sqrt{\frac{36}{3.14}} \\ r=3.3845 \end{gathered}[/tex]Finally, to get the diameter, multiply the radius by 2.
[tex]\begin{gathered} Diameter=Radius\times2 \\ =3.3845\times2 \\ =6.769 \\ Diameter\approx6.77\;cm \end{gathered}[/tex]The diameter of the circle is approximately 6.77 cm.

Answers
Solution
- We are asked to find the y-intercept of the graph of:
[tex]y=2.5x[/tex]- In order to find the y-intercept, we need to know the definition of the y-intercept.
- The y-intercept is the y-value where the graph crosses the y-axis.
- An implication of this definition is that whenever the graph crosses the y-axis, the x-value at that point is zero. This means that we simply need to substitute x = 0 into the equation given to us to find the y-intercept of the graph.
- The y-intercept can thus is gotten as follows:
[tex]\begin{gathered} y=2.5x \\ \text{put }x=0 \\ y=2.5(0) \\ \\ \therefore y=0 \end{gathered}[/tex]Final Answer
The y-intercept of the graph is y = 0 (OPTION B)

Answers
Unit price of a frozen orange juice which costs $1.51 for 14 ounces = $0.108 per ounce
Unit price of a frozen orange juice which costs $0.51 for 4 ounces = $0.128
The better buy is the frozen orange juice which costs $1.51 for 14 ounces
Option B
Explanations:Cost of 14 ounces of orange juice = $1.51
Cost od 4 ounces of orange juice = $0.51
Unit price of a frozen orange juice which costs $1.51 for 14 ounces
Unit price = $1.51 / 14
Unit price of a frozen orange juice which costs $1.51 for 14 ounces = $0.108 per ounce
Unit price of a frozen orange juice which costs $0.51 for 4 ounces
Unit price = $0.51 / 4
Unit price of a frozen orange juice which costs $0.51 for 4 ounces = $0.128
The better buy is the one with the lower unit price
Since the frozen orange juice which costs $1.51 for 14 ounces has the lower unit price, it is the better buy

Answers
Answer
Option B is correct.
the solutions to the system of equations include
(-3, 7) and (1, -1)
Step-by-step Explanation
The question is to solve the system of equations
y = x² - 2 ..... equation 1
y = -2x + 1 ..... equation 2
To solve this, we can just equate the expression given for y in equation 1 to the expression given for y in equation 2.
y = x² - 2
y = -2x + 1
Since
y = y
x² - 2 = -2x + 1
x² + 2x - 2 - 1 = 0
x² + 2x - 3 = 0
This gives a quadratic equation which we will now solve
x² + 2x - 3 = 0
x² + 3x - x - 3 = 0
x (x + 3) - 1 (x + 3) = 0
(x - 1) (x + 3) = 0
So,
x - 1 = 0 or x + 3 = 0
x = 1 or x = -3
If x = 1,
y = x² - 2
= 1² - 2
= 1 - 2
= -1
x = 1, y = -1
If x = -3
y = x² - 2
= (-3)² - 2
= 9 - 2
= 7
x = -3, y = 7
So, the solutions to the system of equations include
x = -3, y = 7, that is, (-3, 7)
And
x = 1, y = -1, that is, (1, -1)

The line M is parallel to the line y=-2x+2 and goes through the origin. Which of these points is on the line M? (-2,-4)(1,1)(2,-2)(-2,4)
Answers
Answer:
(-2,4)
Explanation:
Two lines are said to be parallel if their slopes are the same.
Comparing the line y =-2x+2 to the slope-intercept form y=mx+b, the slope of the line is -2.
Therefore, the slope of line M that is parallel to it is also - 2.
Since the line M goes through the origin, the y-intercept of line M is 0.
Therefore, the equation of line M is:
[tex]y=-2x[/tex]Therefore, the point which is on line M is the point that satisfies the equation above.
This point is (-2,4).

Answers
STEP - BY - STEP EXPLANATION
What to find?
The equation for the hyperbola that models the sides of the cooling tower assuming that the center of the hyperbola occurs at the height for which the diameter is least.
Given:
Minimum diameter = 76 feet
Height = 173 feet
Diameter of the top of cooling tower = 93 feet
Total height of tower = 250 feet
Consider the general hyperbolic formula below:
[tex]\frac{x^2}{a^2}-\frac{y^2}{b^2}=1[/tex]But;
2a = 76
⇒ a = 38
x=93/2 =46.5
y=250 - 173 =77
Substitute the values into the formula above and determine the value of b.
[tex]\frac{(46.5)^2}{38^2}-\frac{77^2}{b^2}=1[/tex][tex]b=109.18[/tex]Now substitute the values a= 38 and b=109.18 into the general formula

Determine the independent and dependent quantities in each scenario include when possible Part A: A lamp manufacturing company produces 750 lamps per shift Part B:a grocery store sells pears by the pound. A customer purchases 3 pounds by $5.07
Answers
Here, we want to establish the independent and independent quantities in each of the parts
The independent quantities are simply the quantities that do not depend on the dependent quantity. The dependent quantity are the quantities that depend on the independent quantity
a) Here, we have 750 lamps produced per shift
This is obtained by dividing the number of lamps produced by the number of shifts it took to produce them
In this case, the number of lamps produced is dependent on the number of shifts'
Number of shifts is the independent variable while the number of lamps is the dependent variable
b) Here, the cost per pair is 5.07/3 = 1.69
So here, the cost is dependent on the number of pears
The number of pears is the independent variable while the cost of the pears is the dependent variable
