What is the area of an equilateral triangle with perimeter 24 inches?
If the quadratic parent function is reflected in the y-axis and vertically compressed by a factor of 1⁄2, write an equation to represent the new function.
Answer:
h(x) = 1/2f(-x)Step-by-step explanation:
Let the parent function be:
f(x)Reflection over y-axis:
g(x) → f(-x)Vertical compression by a factor of 1/2:
h(x) → 1/2g(x)Final function in terms of parent function:
h(x) = 1/2f(-x)In the accompanying diagram ab is tangent to circle O at B and ACD is a secant.
If AB=9 and AD=27, find AC
Answer:
AC = 3
Step-by-step explanation:
Based on tangent and secant theorem, thus:
AB² = AC × (AC + CD)
AB = 9
AD = AC + CD = 27
Plug in the values
9² = AC × (27)
81 = AC × 27
Divide both sides by 27
81/27 = AC
3 = AC
AC = 3

Step-by-step explanation:
A cylinder and its dimensions are shown in the diagram.
Which equation can be used to find v, the volume of the cylinder?
5 in.-
A v = 7(2.5h)
B v = (5h)?
ע
C v= *(2.5) n
Dv = (5)n
h in.
What is the volume of the cylinder? Round to the nearest tenths. Show your work.
Answer:
C. V = π(2.5)²h
Volume = 19.6h
Step-by-step explanation:
Radius (r) of cylinder = ½ of 5 = 2.5 in.
Height (h) = h in.
Volume of a cylinder = πr²h
Equation that can be used to find B:
Plug in the values into the volume formula
V = π(2.5)²h
Volume = 19.6h
For the image above, which action below allows the scale to be balanced?
Add 3 blocks to the right side.
Add 4 blocks to the right side.
Take away 3 blocks from the left side.
Take away 5 blocks from the left side.
Answer:
B is correct
Step-by-step explanation:
I took the flvs test
The action to make both side balanced
Take away 5 blocks from the left side.
What is Balanced?In science, if an object is still, we say it is balanced. An object is in an equilibrium state when it is balanced. Any forces acting on the object are counterbalanced by forces moving the other way. The average location of the gravitational pull on an object is known as the centre of gravity.
We have the figure.
On right side there are total 8 weights.
and, on left there are total 3 weights.
So, the difference of blocks on
= 8- 3
= 5 blocks
So, take away 5 blocks from left.

Density is the amount of mass in a certain volume. Density is recorded in units of grams per milliliter
(g/mL). What is the density of an object is its mass 100g and its volume is 50mL?
a 0.5 g/mL
b 2 g/mL
c 50 g/mL
d 5,000 g/mL
Answer:
Density = mass/volume
Density = 100g/50mL
Density = 2g/mL, so b is correct
Let me know if this helps!
Answer:
b. 2 g/ml
Step-by-step explanation:
As we know density is defined as mass per unit volume so here
Density is recorded in units of grams per milliliter
So Now
Mass (m) = 100 g
Volume (V) = 50 ml
Density (d)
= m/v
= 100 / 50
= 2 g /ml

Solve each equation algebraically
Answer:
x=8
Step-by-step explanation:
Answer:
35
Step-by-step explanation:
I am assuming you want me to answer the equation provided in the picture, therefore I will provide you with the answer.
So we have [tex]\frac{3}{5} x[/tex] = 21
When it comes to equations with a variable, our goal is to isolate the variable, so let's start.
[tex]\frac{3}{5} x[/tex] = 21
1. Combine multiplied terms into a single fraction :
[tex]\frac{3x}{5}[/tex] = 21
2. Multiply both sides by the denominator :
5 * 3/5 = 3
5 * 21 = 105
3x = 105
3. Divide both sides by 3 :
[tex]\frac{3x}{3} = \frac{105}{3 }[/tex]
x = 35

Answer:
[tex]\frac{9}{5}[/tex] or [tex]1\frac{4}{5}[/tex]
Step-by-step explanation:
First add 1/5 from both sides to get 2/3x > 6/5. This can then be simplified to x > 18/10. 18/10 is the same as 9/5. And 9/5 is also 1 4/5.
Hope it helps!
Answer:
[tex]x>\frac{9}{5}[/tex]
Step-by-step explanation:
To reduce any confusion later on in the problem the first step should getting the fractions to have an equal denominator, this can be done by finding the LCF, or Least Common Factor.
In this case the least common factor is [tex]15[/tex], [tex]3[/tex] × [tex]5 = 15[/tex], and [tex]5[/tex] × [tex]3 = 15[/tex]; whatever you do to the denominator has to be done to the numerator
[tex]\frac{2}{3}[/tex] × [tex]\frac{5}{5} = \frac{10}{15}[/tex] [tex]\frac{1}{5}[/tex] × [tex]\frac{3}{3} =\frac{3}{15}[/tex]
Now that the denominators are equal, lets input the values into the original equation:
[tex]\frac{10}{15} x-\frac{3}{15} >1[/tex]
add [tex]\frac{3}{15}[/tex] to both sides, to isolate the variable
[tex]\frac{10}{15}x > 1\frac{3}{15}[/tex] [tex]or \frac{18}{15}[/tex]
divide
both sides by [tex]\frac{10}{15}[/tex], when you divide fractions you multiply by the reciprocal of the divisor, then you multiply the numerators by the numerators and the denominators by the denominators. [tex]18[/tex] × [tex]15[/tex][tex]=270[/tex] , [tex]15[/tex] × [tex]10=150[/tex]
[tex]x>\frac{18}{15}[/tex] × [tex]\frac{15}{10}[/tex] ⇒ [tex]x>\frac{270}{150}[/tex]
[tex]270[/tex] and [tex]150[/tex] have a GCF, or Greatest Common Factor of [tex]30[/tex] which simplifies the answer to:
[tex]x>\frac{9}{5}[/tex]

One of the legs of a right triangle is 9 cm. If the area of the triangle is 225 cm², then the length of the other leg is
if you tell correctly I will give brainlist
Given:
One of the legs of a right triangle is 9 cm.
The area of the triangle is 225 cm².
To find:
The length of the other leg.
Solution:
The area of a triangle is
[tex]Area=\dfrac{1}{2}\times Base\times Height[/tex]
The area of a right triangle is
[tex]Area=\dfrac{1}{2}\times (leg_1)\times (leg_2)[/tex]
Let x be the length of other leg.
[tex]225=\dfrac{1}{2}\times (9)\times (x)[/tex]
[tex]2\times 225=9x[/tex]
[tex]\dfrac{450}{9}=x[/tex]
[tex]50=x[/tex]
Therefore, the length of the other leg is 50 cm.

Find the equation of the linear function represented by the table below in slope-
intercept form.
Answer:
f(x) = 5x - 5
Step-by-step explanation:
Let the equation of the linear function is,
f(x) = mx + b
Here, m = Slope of the graph
b = y-intercept
Slope of the line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{(y_2-y_1)}{(x_2-x_1)}[/tex]
From the table attached,
Slope of the line passing through (2, 5) and (6, 25) will be,
m = [tex]\frac{25-5}{6-2}[/tex]
m = 5
Equation of the linear function will be,
f(x) = 5x + b
Since, a point (10, 45) lies on the function,
45 = 5(10) + b
b = 45 - 50
b = -5
Equation of the linear function will be,
f(x) = 5x - 5

Coach Jump is standing on a platform watching the football team practice. If the platform is 12 feet high and the quarterback is standing 23 feet from the base of the platform, find the angle of depression from Coach Jump to the quarterback. Round to the nearest degree.
Answer:
62 degrees.
Step-by-step explanation:
What you will have here is a right triangle. For the vertical put 12 ft and for the horizontal put 23 ft. You are trying to find the angle between the verticle and hypotenuse. This is what tangent is used for since you know the opposite and you know the adjacent lengths.
But since you are trying to find the angle you need to do an inverse tangent (also called arctangent)
ArctanФ = Adj/opposite
ArctanФ = 12/23 = 27.47 degrees. Rounded to the nearest degree is 27 degrees, if it wants rounded up its 28 degrees.
The angle of depression from Coach Jump to the quarterback is 27.6°.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = Perpendicular / Hypotenuse
Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
In this diagram,
C represents Coach Jump,
B represents the base of the platform,
θ represents the angle of depression from Coach Jump to the quarterback.
Now,
We want to find θ.
We can use the tangent function,
So,
tan Ф = 12/23
Ф = [tex]tan^{-1}[/tex] 12/23
Ф = 27.55°.
Thus,
The angle of depression from Coach Jump to the quarterback is 27.6°.
