What is the equation of the line that passes through the point (-4, 7) and has an
undefined slope?
Answer:
x = -4
Step-by-step explanation:
Since the slope is undefined, the line is a vertical line. All vertical lines have an equation x = k. In your problem k = -4, so the equation of the line is x = -4
A person invests 8000 dollars in a bank. The bank pays 5% interest compounded monthly. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 14100 dollars?
Answer:
3 years
Step-by-step explanation:
To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 14100 dollars is: 11.6.
TimeUsing this formula
A=P(1+r/n)^nt
Let plug in the formula
14,100=8000(1+0.05)^t
(1+0.05)^t=14,100/8000
(1+0.05)^t=1.7625
1.05^t=1.7625
t=log(1.7625)/log(21/20)
t=0.246/0.021189
t=11.6
Therefore how long must the person leave the money in the bank until it reaches 14100 dollars is: 11.6.

Convert this decimal to a simplified fraction:
0.32
Answer:
[tex] \frac{8}{25} [/tex]
Explanation
[tex] \frac{0.32}{100} [/tex]
2 numbers are beyond the decimal point. This is in the hundredths place. So place the decimal upon 100. It will become
[tex] \frac{32}{100} [/tex]
To simplify this fraction find the lowest common multiple that can go both in 32 and a 100 without leaving a remainder. That would be 4.
32 ÷ 4 = 8
100÷4 = 25

A painter paints rooms in a house. The painter purchases 12 gallons of paint and uses 4 gallons on the first day of work.
Which equation could be used to find how many gallons of paint are left, g?
g+4=12
g÷12=4
4×g=12
12+g=4
Answer:
g+4=12
Step-by-step explanation:
Since the painter used 4 of the 12 gallons, the painter now has 8 gallons, so g=8.
The equation g+4=12 represents this because if we solve it by isolating g then we get that g=8.

What is the area of the trapezoid shown below?
units2
Answer and Step-by-step explanation:
Use the Pythagorean Theorem to solve for the height.
[tex]a^{2}+ b^{2}= c^{2} \\\\\\4^{2} + b^{2} = 5^{2}\\\\\\16 + b^{2} = 25\\\\\\b^{2} = 9\\\\\\b = 3[/tex]
The height of the triangle is 3.
Now we can solve the shapes in the trapezoid.
4 times 3 = 12 (Rectangle)
[tex]\frac{4 * 3}{2}[/tex] = [tex]\frac{12}{2}[/tex] = 6 (Triangle)
12 + 6 = 18 (Trapezoid)
The area of the trapezoid is 18 [tex]units^{2}[/tex].

8/3 = 3 (c + 5/3) how to solve step by step
Answer:
Step-by-step explanation:
8/3=3(c+5/3)
multiply both sides by 3
8=9(c+5/3)
divide both sides by 9
8/9=c+5/3
subtract 5/3 from both sides
c=8/9-5/3
change 5/3 to 15/9
c=8/9-15/9
c=-7/9

∠xangle, x and \angle y∠yangle, y are supplementary angles. \angle y∠yangle, y measures 142^\circ142 ∘
Answer:
Angle x = 38°
Step-by-step explanation:
It is important to note that:
Two angles are called supplementary when their measures add up to 180 degrees.
Angle x and y are supplementary
Angle y = 142°
Hence,
Angle x = 180° - 142°
Angle x = 38°

PLEASE HELP!!!!!!!!!!!! VOLUME OF A CONE!!!!!!
Hi! Your answer is 125/3 π
Please see an explanation for a clear understanding to the problem.
Any questions about the answer/explanation can be asked through comments! :)
Step-by-step explanation:
For this problem, I'll be demonstrating two methods to solve your problem which are Integration method and Formula method. Let's start with Formula method first!
Formula Method
Volume of Cone Formula
[tex]V=\huge{\frac{1}{3}\pi r^2h}[/tex]
r is a radius. Therefore, r² is a diameter.
h is height of cone.
Our r is 5. Therefore, 5² = 25.
Our h is 5.
Substitute these values in the equation.
[tex]V=\huge{\frac{1}{3}\pi (5)^2(5)}\\V=\huge{\frac{1}{3}\pi (25)(5)} \\V=\huge{\frac{1}{3}\pi (125)}\\V=\huge{\frac{125}{3}\pi}[/tex]
Hence, the volume of a cone is 125/3 pi. If you want in Mixed Number form then It'd be 41 and 2/3 pi [ 41 2/3 pi]
Integration Method - Proof
Let r':r = x:h
Therefore,
[tex]\huge{\frac{r'}{r}=\frac{x}{h}}\\\huge{r'=\frac{x}{h}r[/tex]
r and h both are same (r is still radius while h is still height)
[tex]\huge{S(x)=\pi(r')^2[/tex]
The reason why we add pi because the surface is a circle. If the surface is not a circle, we don't add pi.
[tex]\huge{S(x)=\pi(\frac{x}{h}r)^2}\\\huge{S(x)=\pi(\frac{x^2r^2}{h^2})}\\\huge{S(x)=\frac{\pi r^2}{h^2}x^2}\\[/tex]
The range starts from 0 ≤ x ≤ h
[tex]\huge{V=\int\limits^h_0 {S(x)} \, dx[/tex]
Substitute S(x) in.
[tex]\huge{V=\int\limits^h_0 {\frac{\pi r^2}{h^2}x^2 } \, dx[/tex]
Integrate, separate everything in the integrand out except for x^2
[tex]\huge{V=\frac{\pi r^2}{h^2} \int\limits^h_0 {x^2} \, dx}\\\huge{V=\frac{\pi r^2}{h^2}[\frac{1}{3}x^3]^h__0}}\\\huge{V=\frac{\pi r^2}{h^2}[\frac{1}{3}h^3]}\\\huge{V=\pi r^2[\frac{1}{3}h]}\\\huge{V=\frac{1}{3}\pi r^2h}[/tex]
As you notice, Integration method is pretty useful, but it's mostly for an advanced volume lesson only.
Integration Method - Problem Solving
Let r':r = x:h
r is given as 5
h is given as 5 as well.
Therefore, r':5 = x:5
[tex]\huge{\frac{r'}{5}=\frac{x}{5}}\\\huge{r'=\frac{x}{5}(5)}\\r'=x[/tex]
[tex]\huge{S(x)=\pi(r')^2}\\\huge{S(x)=\pi(x^2)}\\\huge{S(x)=\pi x^2}[/tex]
The range of volume starts from surface to height. Therefore the range is 0 ≤ x ≤ 5
[tex]\huge{V=\int\limits^5_0 {S(x)} \, dx }\\\huge{V=\int\limits^5_0 {\pi x^2} \, dx }\\\huge{V=\pi\int\limits^5_0 {x^2} \, dx }\\\huge{V=\pi[\frac{1}{3}x^3]^5__0}}\\\huge{V=\pi[(\frac{1}{3}(5)^3-\frac{1}{3}(0)^3]}\\\huge{V=\pi[(\frac{1}{3}(125)-0)]}\\ \huge{V=\pi[(\frac{1}{3}(125)]}\\\huge{V=\pi(\frac{125}{3})}\\\huge{V=\frac{125}{3}\pi}[/tex]
Notice that both methods have same answer. Hence, we can conclude that the volume of a cone is 125/3 pi units²

and \text{m}\angle W = 27^{\circ}.m∠W=27
∘
. Find \text{m}\angle X.m∠X.
Answer:
m<X = 27 degrees
Step-by-step explanation:
From △VWX, since WX = XV, this mean that the triangle is isosceles
The base angle of an isosceles triangle are equal hence <W = <X
Since <W = 27 degrees, hence m<X = 27 degrees
