Answer:
15.8
Step-by-step explanation:
The formula would be V = Bh, the Base being LxW.
Since we already know the base and volume, we can substitute it into the formula.
306.52 = 19.4(h). Divide by 19.4, and you get 15.8 as your answer.
Hope that helps! Tell me if im worng, im only a student .m.
Solve for x.
-30 = 5(x+1)
Answer:
−30=5(x+1)
Step 1: Simplify both sides of the equation.
−30=5(x+1)
−30=(5)(x)+(5)(1)(Distribute)
−30=5x+5
Step 2: Flip the equation.
5x+5=−30
Step 3: Subtract 5 from both sides.
5x+5−5=−30−5
5x=−35
Step 4: Divide both sides by 5.
5x5=−355
x=−7
Answer:
x=−7
Answer:
x = -7
Step-by-step explanation:
Since this problem has the distributive property, we can simplify the problem.
-30 = 5x + 5
Now we have to subtract 5 from both sides because of the +5.
-35 = 5x
To find the answer, we have to move all the real numbers to one side, the variable on the other. To do this, we can simply divide both sides by 5.
-7 = x
x = -7

Andy made a spirometer for a physics experiment. The spirometer is designed to measure the volume of air in a person's lungs. Andy found that when he breathes normally, he inhales and exhales 0.5 of a liter of air per breath. He also found that when breathing normally, after exhaling, he still has 2 liters of air in his lungs.
Andy recorded 15 breaths in one minute, starting at the beginning of an exhale.
If Andy inhaled and exhaled the exact same amount of air in each breath, which of the following functions best models the amount of air in Andy's lungs t seconds after he started recording?
A(t)=0.25cos(x/2 2)+2.25

Answer:
B
Step-by-step explanation:
I used the quadratic formula
Answer:
B
Step-by-step explanation:
Given
(x + 5)² = 48 ( take the square root of both sides )
x + 5 = ± [tex]\sqrt{48}[/tex] = ± [tex]\sqrt{16(3)}[/tex] = ± 4[tex]\sqrt{3}[/tex] ( subtract 5 from both sides )
x = - 5 ± 4[tex]\sqrt{3}[/tex] → B
What's the equation of the line that's a perpendicular bisector of the segment connecting A (–2, 8) and B (–4, 2)?
Question 12 options:
A)
y = –1∕3x – 3
B)
y = –1∕3x + 3
C)
y = 1∕3x + 3
D)
y = –1∕3x + 4
Answer:
D
Step-by-step explanation:
The required line is perpendicular bi sector. So it goes through the midpoint of AB. Find the midpoint of AB
Midpoint [tex](\frac{x_{1}+x_{2}}{2} , \frac{y_{1}+y_{2}}{2})\\[/tex]
Midpoint of AB = [tex](\frac{-2 + [-4]}{2} , \frac{8+2}{2})[/tex]
[tex]=(\frac{-6}{2} , \frac{10}{2})\\\\=(-3 , 5)[/tex]
Find the slope of AB, [tex]m_{1}[/tex]
slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\[/tex]
[tex]=\frac{2 - 8}{-4-[-2]}\\\\=\frac{-6}{-4+2}\\\\=\frac{-6}{-2}\\\\=3[/tex]
Slope of the perpendicular line to AB = [tex]\frac{-1}{m_{1}}[/tex] = -1/3
The required line passes through (-3, 5) and has slope -1/3
Equation of required line : y - y1 = m (x -x1)
[tex]y - 5 = \frac{-1}{3} (x - [-3])\\\\y-5=\frac{-1}{3} ( x +3)\\\\y-5=\frac{-1}{3}x + 3 *\frac{-1}{3}\\\\y-5=\frac{-1}{3}x-1\\\\y=\frac{-1}{3}x-1+5\\\\y=\frac{-1}{3}x + 4[/tex]
Answer:
Step-by-step explanation:
D)
y = –1∕3x + 4

Which of the following statements NOT true?
what is the area of the parallelogram
A. 11in2
B. 22in2
C. 45in2
D. 60in2
Answer:
Step-by-step explanation:
Area of a parallelogram is base times height. So 15x4
It’s 60in^2
So D
Answer:
D. 60 inches^2
Step-by-step explanation:
The area of a parallelogram can be found using:
a=bh
We know that the height is 4 inches, and the base is 15 inches. Therefore, we can substitute 4 in for h and 15 in for b.
a=4*15
Multiply 4 and 15
a=60
Area is always units^2. We know the units are inches, therefore the area is:
60 inches^2, or choice D

2. Find the value of x.
BI
3(x + 2)
24
Ox=6
Ox=10
3(x+2
Ox= 24
3x + 6
Ox=8
3x +
Answer:
x = 6
Step-by-step explanation:
3(x + 2) =24
Divide each side by 3
3/3(x+2) = 24/3
x+2 = 8
Subtract 2 from each side
x+2-2 = 8-2
x = 6
On a coordinate plane, triangle A B C has points (negative 3, negative 1), (negative 2, negative 3), (1, negative 1) and is reflected across y = 1. Reflect the figure over the line y = 1. Which is point A’ after the reflection? A’(–3, 1) A’(–3, 3) A’(–3, 2) A’(1, 1)
Answer:
A' = (-3, 3)
Step-by-step explanation:
If the points are as follows:
A = (-3, -1)
B = (-2, -3)
C = (1, -1)
When reflecting across a y axis the x values remain the same.
When reflecting across y = 1 the y values will remain equal distant from y = 1.
A' = (-3, 3) y value = |-1 - 1| = 2 + 1 = 3
B' = (-2, 5) y value = |-3 - 1| = 4 + 1 = 5
C' = (1, 3) y value = |-1 - 1| = 2 + 1 = 3
Answer:
A' = (-3, 3)

Which line has a slope of -2 and goes through the point (-2, 3) ?
y=−2x−1
y=−1/2x+3
y=1/2x−5
y=2x+1
Answer:
y=-2x-1
Step-by-step explanation:
Since the m term in this equation (the number that comes right before the x) is -2, that means that the slope of this line is -2.

2sin^2 - x - Sinx =1 and sec x csc x (tanx+ cotx) = sec^2x + csc^2x is not an identity. Option B and C is correct.
Out of Four options are given, which of them is not an identity is to be determined.
What is identity?An identity is the common case formula that helps to solve mathematics.
1)
[tex]2cos^2x-1 = 1 - 2 sin^2x\\ \\cos2x =cos2x[/tex]
It is also a perfect identity.
2)
[tex]secx cscx(tanx+ cotx) = sec^2x + csc^2x\\\\\\sec x cscx (sinx/cos x + cosx/sinx) = sec^2 + csc^2x\\\\secx cscx (sin^x+cox^2x/cosxsinx) = sec^2x +csc^2x[/tex]
It is also not an identity.
3) 2sin^2-X- Sinx=1
It's not an identity cause it is form of equation and contain -x.
4)
[tex]sin^2x+ tan^2x + cos^2x = sec^2x\\ sin^2x + cos^2x = sec^2x -tan^2x = 1[/tex]
It is a perfect identity.
Thus, 2sin^2- x - Sinx =1 and sec x csc x (tanx+ cotx) = sec^2x + csc^2x is not an identity. Option B and C is correct.
