Answer:
y = 8x + 13
Step-by-step explanation:
slope-intercept form: y = mx + b
Given equation: [tex]y = -\frac{1}{8}x -2[/tex]
Second equation: unknown
Slope: unknown
Given point: (-2, -3)
When two lines are perpendicular, their slopes are negative reciprocals. So, since the slope(m) of the given line is [tex]-\frac{1}{8}[/tex], the slope of the line perpendicular to it is 8.
Now we know the slope of the line. To find the y-intercept, input the values of the slope and the given point into the equation format and solve for b:
y = mx + b
-3 = 8(-2) + b
-3 = -16 + b
13 = b
The y-intercept is 13.
Now that we know the slope and the y-intercept, we can write the equation:
y = 8x + 13

The minimum diameter for a hyperbolic cooling tower is 57 feet...
Answer:
Can give you the example then you have to figure out.
Step-by-step explanation:
We are assuming the center of the tower is at the origin, so we can use the standard form of a horizontal hyperbola centered at the origin: \displaystyle \frac{{x}^{2}}{{a}^{2}}-\frac{{y}^{2}}{{b}^{2}}=1
a
2

=1, where the branches of the hyperbola form the sides of the cooling tower. We must find the values of \displaystyle {a}^{2}a
2
and \displaystyle {b}^{2}b
2
to complete the model.
First, we find \displaystyle {a}^{2}a
2
. Recall that the length of the transverse axis of a hyperbola is \displaystyle 2a2a. This length is represented by the distance where the sides are closest, which is given as \displaystyle \text{ }65.3\text{ } 65.3 meters. So, \displaystyle 2a=602a=60. Therefore, \displaystyle a=30a=30 and \displaystyle {a}^{2}=900a
2
=900.
To solve for \displaystyle {b}^{2}b
2
, we need to substitute for \displaystyle xx and \displaystyle yy in our equation using a known point. To do this, we can use the dimensions of the tower to find some point \displaystyle \left(x,y\right)(x,y) that lies on the hyperbola. We will use the top right corner of the tower to represent that point. Since the y-axis bisects the tower, our x-value can be represented by the radius of the top, or 36 meters. The y-value is represented by the distance from the origin to the top, which is given as 79.6 meters. Therefore,

The shape of hyperbolic cooling tower is a conic section that can be described with a formula equation.
a = 28.5, b ≈ 52.65
[tex]Equation \ of \ hyperbola;\ \dfrac{x^2}{28.5^2} - \dfrac{(y-155)^2}{56.62^2} = 1[/tex]
Reasons:
The parameters of the hyperbolic cooling tower are;
Minimum diameter = 57 feet
The height at which the diameter occurs = 155 ft.
The diameter of the tower = 175 feet
Total height of the tower = 200 feet
Height at which the center of the hyperbola occurs = 155 feet
Solution:
The equation of a hyperbola is; [tex]\dfrac{(x - h)^2}{a^2} - \dfrac{(y- k)^2}{b^2} = 1[/tex]
The center of the hyperbola = (0, 155)
[tex]a = \dfrac{57}{2} = 28.5[/tex]
At y = 155,
Therefore;
[tex]\dfrac{x^2}{28.5^2} - \dfrac{(y -155)^2}{b^2} = 1[/tex]
At y = 200 feet [tex]x = \dfrac{75 \ feet}{2} = 37.5 \ feet[/tex]
Therefore;
[tex]\dfrac{37.5^2}{28.5^2} - \dfrac{(200 -155)^2}{b^2} = 1[/tex]
b² = 2769.0340909
b ≈ 52.62
The equation of the hyperbola is therefore;
[tex]\dfrac{x^2}{28.5^2} - \dfrac{(y-155)^2}{56.62^2} = 1[/tex]

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find out the time at which the rocket will reach its max, to the nearest 100th of a second.
y=−16x 2 +193x+128
Let x be -b/2a
x = -193/2•(-16)
x = -193/-32
x = 6.03125
Now, plug this value of x into every x in the function and simplify. The max is the y value.
Can you finish?
The time at which the rocket will hit the ground to the nearest hundredth of seconds is 13 seconds.
What is a quadratic equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.
As per the given height of tower y in terms of time is seconds x
y = -16x² + 193x + 128
The height of the tower when the rocket hit the ground will be zero.
Thus, y = 0
0 = -16x² + 193x + 128
16x² - 193x - 128=0
By quadratic equation formula,
x = [-(-193) ± √((-193)²-4×16×(-128))]/ 2×16
x = [193 ± 213.168]/32
x = 12.69 and x = -0.63 since time can be never negative thus 12.69 seconds will be correct.
12.69 to the nearest hundred is 13.
Hence "The time at which the rocket will hit the ground to the nearest hundredth of seconds is 15 seconds".

how many hectares of land are there in a field that is 450 m long and 1200 dm wide.
Answer:
Step-by-step explanation:
Given
[tex]Length = 450\ m[/tex]
[tex]Width = 1200\ m[/tex]
Required
Determine the number of hectares in this dimension
First, we need to calculate the area of the land
[tex]Area = Length * Width[/tex]
[tex]Area = 450m * 1200dm[/tex]
Convert dm to m
[tex]Area = 450m * 120m[/tex]
[tex]Area = 54 000 m^2[/tex]
[tex]1 hectare = 0.0001m^2[/tex]
So, we have:
[tex]1\ hectare = 0.0001m^2[/tex]
Multiply by 54000
[tex]Hectare = 0.0001 * 54000[/tex]
[tex]Hectare = 5.4[/tex]
Hence, there are 5.4 hectares

The third and the sixth term of a geometric progression are 24 and 64/9 respectively. Find
a) the first term and common ratio
b) the sum of the first five terms
Answer:
Ai. Common ratio = 2/3
Aii. First term = 54
B. Sum of the first five terms = 422/3
Step-by-step explanation:
From the question given above, the following data were obtained:
3rd term (T3) = 24
6Th term (T6) = 64/9
First term (a) =?
Common ratio (r) =?
Sum of the first five terms (S5) =?
Ai. Determination of the common ratio (r).
T3 = ar²
T3 = 24
24 = ar²....... (1)
T6 = ar⁵
T6 = 64/9
64/9 = ar⁵......... (2)
The equation are:
24 = ar²....... (1)
64/9 = ar⁵......... (2)
Divide equation 2 by equation 1.
64/9 ÷ 24 = ar⁵ / ar²
64/9 × 1/24 = r³
8/27 = r³
Take the cube root of both side
r = 3√(8/27)
r = 2/3
Thus, the common ratio is 2/3
Aii. Determination of the first term (a).
T3 = ar²
3rd term (T3) = 24
Common ratio (r) = 2/3
First term (a) =?
24 = a(2/3)²
24 = 4a/9
Cross multiply
24 × 9 = 4a
216 = 4a
Divide both side by 4
a = 216/4
a = 54
Thus, the first term (a) is 54
B. Determination of the sum of the first five terms.
Common ratio (r) = 2/3
First term (a) = 54
Number of term (n) = 5
Sum of first five terms (S5) =?
Sn = a[1 –rⁿ] / 1 – r
S5 = 54[1 – (⅔)⁵] / 1 – ⅔
S5 = 54 [1 – 32/243] / ⅓
S5 = 54 (211/243) × 3
S5 = 54 × 211/81
S5 = 6 × 211/9
S5 = 2 × 211/3
S5 = 422/3
Thus, the sum of the first five terms is 422/3

Renting the ice-skating rink for a birthday party costs $200 plus $4 per person. the rental costs $324 in total
If we can translate the statement "The ice rink costs $200 plus $4 per person to rent for a birthday celebration and the entire cost of the rental is $324" into an algebraic equation, we get 4x + 200 = 324, where x is the number of people at the birthday party. The solution of this equation i.e. the number of people at the birthday party is 31.
What is an algebraic equation?A statement of the equivalence of two expressions created by executing algebraic operations on a set of variables, such as addition, subtraction, multiplication, division, raising to a power, and root extraction, is known as an algebraic equation.
How to solve this problem?Let the number of people at the birthday party be x.
Given that the ice rink costs $200 plus $4 per person to rent for a birthday celebration. So, the rent is 4x + 200.
Also, given that the entire cost of the rental is $324.
We can write the corresponding algebraic equation as
4x + 200 = 324
Now we have to solve this equation.
So, 4x = 324 - 200 = 124
i.e. x = 124/4 = 31
Therefore the required algebraic equation is 4x + 200 = 324, where x is the number of people at the birthday party. Also, the solution of this equation i.e. the number of people at the birthday party is 31.

Each good worker can paint my new house alone in 12 hours. Each bad worker can paint my house alone in 36 hours. I need my house painted in 3 hours. If I can only find 3 good workers, how many bad workers must I also find in order to have my house painted on time?
Pls give explanation
In 3 hours, one good worker can paint one fourth of your house. Three good workers can thus paint three fourths of your house in three hours, leaving one fourth to be done by bad workers.
One bad worker can paint one twelfth of your house in 3 hours. There are three twelfths in one fourth, so you will need to hire three bad workers to have your house painted on time.
