Answers
Answer:
x = 19
Step-by-step explanation:
l, m and n are the parallel lines.
Two transversal lines are intersecting these parallel lines.
By Intercept theorem,
Lengths of intercepts between the parallel lines are proportional.
[tex]\frac{38}{8}=\frac{x}{4}[/tex]
x = [tex]\frac{4\times 38}{8}[/tex]
x = 19
Therefore, x = 19 will be the answer.

Calculators cost $12.99 each, rulers cost $0.49 each, pencils cost $0.10 each, and erasers
cost $0.05 each. How much would Mrs. Algebra's single order be? Use the expression below
to calculate the total.
Answers
Given :
Calculators cost $12.99 each, rulers cost $0.49 each, pencils cost $0.10 each, and erasers cost $0.05 each.
To Find :
How much would Mrs. Algebra's single order be.
Solution :
Total price paid by Mrs. Algebra = Price of pencil + price of ruler + price of calculator + price of eraser.
T = $(0.10 + 0.49 + 12.99 + 0.05)
T = $13.63
Therefore, Mrs. Algebra's single order cost is $13.63 .
Hence, this is the required solution.

A bowling ball is dropped from a height of 50 feet
a. Write a function that gives the height h (in feet) of the bowling ball after t seconds.
h(t)=
b. Find the height of the bowling ball after 1 second.
c. How long does the bowling ball take to hit the ground? Round your answer to the nearest hundredth of a second.
Answers
Answer:
A. The function that gives the height of the bowling ball after t seconds is [tex]h(t) = 50-16.087\cdot t^{2}\,\,\,[ft][/tex].
B. The height of the bowling ball after 1 second is 33.913 feet.
C. The bowling ball will take approximately 1.763 seconds to hit the ground.
Step-by-step explanation:
A. From Physics we notice that ball experiments a free-fall, which is an uniform accelerated motion due to gravity and where air friction and effects of the Earth's rotation are neglected. The height of the ball is described by the following kinematic equation:
[tex]h(t) = h_{o}+v_{o}\cdot t +\frac{1}{2}\cdot g \cdot t^{2}[/tex] (1)
Where:
[tex]h_{o}[/tex] - Initial height of the ball, measured in feet.
[tex]v_{o}[/tex] - Initial velocity of the ball, measured in feet per second.
[tex]t[/tex] - Time, measured in seconds.
[tex]g[/tex] - Gravitational acceleration, measured in feet per square second.
If we know that [tex]h_{o} = 50\,ft[/tex], [tex]v_{o} = 0\,\frac{ft}{s}[/tex] and [tex]g = -32.174\,\frac{ft}{s^{2}}[/tex], then the function that gives the height of the bowling ball after t seconds is:
[tex]h(t) = 50-16.087\cdot t^{2}\,\,\,[ft][/tex] (2)
The function that gives the height of the bowling ball after t seconds is [tex]h(t) = 50-16.087\cdot t^{2}\,\,\,[ft][/tex].
B. If we know that [tex]t = 1\,s[/tex], then the height of the bowling ball is:
[tex]h(1) = 50-16.087\cdot (1)^{2}[/tex]
[tex]h(1) = 33.913\,ft[/tex]
The height of the bowling ball after 1 second is 33.913 feet.
C. The bowling ball hits the ground when height is zero. Let equalize (1) to zero and solve the resulting expression:
[tex]50-16.087\cdot t^{2} = 0[/tex]
[tex]16.087\cdot t^{2} = 50[/tex]
[tex]t \approx 1.763\,s[/tex]
The bowling ball will take approximately 1.763 seconds to hit the ground.

how do you figure out the square root of z^2+8z+16?
Answers
Step-by-step explanation:
Hey there!
Given;
[tex] = \sqrt{ {z}^{2} + 8z + 16} [/tex]
Looking through question, we can bring it to perfect square to remove the (√) sqrt.
[tex] \sqrt{( {z)}^{2} + 2.4x + {4}^{2} } [/tex]
We made this to bring it in the form of (a+b)^2. As (a+b)^2 = a^2 + 2.a.b + b^2.
Now, our question looks like similar to the formula.
So, We can write it as:
[tex] \sqrt{( {z + 4)}^{2} } [/tex]
Now, we can cancel (√) and (^2). And we get
= z + 4

Answers
Answer:

Step-by-step explanation:
9-6

6-5
=3/1
simplify
m=3
The slope can be found by finding the rise and run of the line
The slope of the line that passes through the points (5, 6) and (5, 9) is infinite
Reason:
The given points on the line are; (5, 6) and (5, 9)
The slope of the line that passes through the given points = Required
Solution:
The x-values of the given points are equal, therefore, the equation of the line that passes through the given points is x = 5
The slope, m, of the line is infinite because;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]Therefore, for the given points, (5, 6) and (5, 9), we have;
[tex]Slope, \, m =\dfrac{9-6}{5-5} = \dfrac{9}{0} = \infty[/tex]Therefore, the slope of the line that passes through the points (5, 6) and (5, 9) is infinite

Solve for the value of x in this equation: 146=2+7x+5x
Answers
Answer:
x=12
Step-by-step explanation:
First combine like terms
146=2+12x
Then I like to put it into y=mx+b form.
146=12x+2
Next you subtract 2 from both sides.
146-2=12x+2-2
144=12x
Finally you divide 12 on both sides and in the end you get x=12. Hope this helps.

Since the -5 isn’t inside the absolute value bars, then it couldn’t shift left or right, so eliminate those options from your mind.

[tex](9s + 8)° + 37° = 180°[/tex]
Because they make straight line.
[tex]9s + 8 + 37 = 180[/tex]
[tex]9s + 45 = 180[/tex]
Subtract sides 45
[tex]9s + 45 - 45 = 180 - 45[/tex]
