Answer:
19.7ft
Step-by-step explanation:
o^2+a^2=h^2
\dpi{100} h^{2}=(10ft)^{2} +(17ft)^{2}
h^2=100ft^2+289ft^2
h=389ft^2−−−−−√
→19.7ft
Answer:
Step-by-step explanation:
a^2 + b^2 = c^2
where a and b are the legs of the triangle and c is the hypotenuse
so 8^2 + 12^2 = c^2
64 + 144 = c^2
208 = c^2
take the square root of both sides
c = 14.422
which point on the number line best represents the square root of 22

A 12 foot ladder is leaning up against a wall. If the angel made between the ladder and the ground is 80 degrees. How far up can the ladder reach the wall? Round to the nearest tenth of a foot
Answer:
11.8 feetStep-by-step explanation:
Given
Length of the ladder = 12foot
angle of elevation = 80 degrees
Required
Height of the wall (opposite side)
The set up will form a right angled triangle where
length of the ladder is the hypotenuse
height of the wall is opposite;
Using SOH, CAH, TOA trig identity
According to SOH
sin 80 = opp/hyp
sin80 = opp/12
opp = 12sin80
opp = 11.82 feet
Hence the height of the wall is 11.8feet (to the nearest tenth)
A bookstore had 45 copies of a magazine. Yesterday, it sold 2/3 of them. Today, it sold 2/5 of what remained. How many copies does the bookstore have left?
Answer:
After the first day, 1/3 of the original amount remained:
... (1/3)·45 = 15
After the second day, 2/3 of that amount remained:
... (2/3)·15 = 10
The bookstore has 10 copies left.
Step-by-step explanation:
Answer:
Step-by-step explanation:
45 copies and sold 2/3= 30 sold so 15 left
15 copies and sold 2/5= 6 sold so 9 left

|10+4x|<14 how do you solve this?
Answer:
-6 < x < 1
Step-by-step explanation:
-14 < 10 + 4x < 14
Subtract 10 from both sides
-24 < 4x < 4
Divide both sides by 4
-6 < x < 1
Answer: - 6 < x < 1
|10 + 4x| < 14
⇔ -14 < 10 + 4x < 14
⇔ -14 - 10 < 4x < 14 - 10
⇔ - 24 < 4x < 4
⇔ -24/4 < x < 4/4
⇔ - 6 < x < 1
Step-by-step explanation:

Answer:
∠ EFG = 83°, ∠ GCE = 97°
Step-by-step explanation:
Since FE and FG are tangents to the circle then
∠ FGC and ∠ FEC are right angles
The sum of the angles in quadrilateral CEFG = 360°
Sum the 4 angles and equate to 360
3x + 11 + 90 + 5x - 23 + 90 = 360, that is
8x + 168 = 360 ( subtract 168 from both sides )
8x = 192 ( divide both sides by 8 )
x = 24
Thus
∠ EFG = 3x + 11 = 3(24) + 11 = 72 + 11 = 83°
∠ GCE = 5x - 23 = 5(24) - 23 = 120 - 23 = 97°
Find the slope of the line. (0,-1) (3,-2)
Answer:
-1/3
Step-by-step explanation:
m = (y2-y1) / (x2-x1)
m = (-2-(-1)) / (3-0)
m = (-2+1) / 3
m = -1/3
Answer:
-1/3
Step-by-step explanation:
equation is y2-y1/x2-x1
So the second y (-2) minus the first y (-1) is -1
And 3-0 is 3. So 3/1

You are a sales clerk in a clothing store. You receive a salary of $320 per week plus a 5% commission on all sales. Write an equation to represent your weekly salary. (Let y equal the weekly salary and x equal the amount of sales.) What are the slope and y-intercept of your equation?
Answer:
slope: 0.05
y-intercept: 320
Step-by-step explanation:
y is the total weekly salary and x is the sales
there is a constant salary of $320, which will be the constant in the equation.
y = mx + b
y = mx + 320
we know there is a 5% commission on all sale, which we can convert to the fraction 0.05.
y = .05x + 320
Now we can see that the slope is .05 and the y-intercept is 320

1. What absolute value expression can be written to determine the distance between 63 feet above sea level and 48 feet below sea level?
Given:
The distance between 63 feet above sea level and 48 feet below sea level.
To find:
The absolute value expression for the given situation.
Solution:
We have,
Distance above the sea level = 63 feet
Distance below the sea level = -48 feet
Here, negative sign represents the distance in below the sea level.
So, absolute value expression that can be written to determine the distance between 63 feet above sea level and 48 feet below sea level is
[tex]Distance=|63-(-48)|[/tex]
[tex]Distance=|63+48|[/tex]
[tex]Distance=|111|[/tex]
[tex]Distance=111[/tex]
Therefore, the required absolute expression is [tex]|63-(-48)|[/tex] and distance is 111 feet.

What is the equation of a line that is parallel to x−2y=−4 and passes through the point (0, 0)?
Enter your answer in the box.
Answer:
The equation of a line that is parallel to x−2y=−4 and passes through the point (0, 0) will be: [tex]x-2y=0[/tex]
Step-by-step explanation:
Given the line
[tex]x-2y=-4[/tex]
[tex]x+4 = 2y[/tex]
[tex]y=\left(\frac{1}{2}\right)x+2[/tex]
[tex]m_1=\frac{1}{2}[/tex]
so, the slope of the line parallel to the given line would have
the same slope as [tex]\frac{1}{2}=m[/tex], and passed through the point (0, 0).
Therefore, the equation of the required line is given by
[tex]y = mx+b[/tex]
[tex]y=\left(\frac{1}{2}\right)x+0[/tex]
[tex]y=\left(\frac{1}{2}\right)x[/tex]
[tex]2y=x[/tex]
[tex]x-2y=0[/tex]
Therefore, the equation of a line that is parallel to x−2y=−4 and passes through the point (0, 0) will be: [tex]x-2y=0[/tex]

Which polynomial function could be represented by the graph below?
Answer:
Option B: f(x) = 2x2 + 2x – 4
Step-by-step explanation:
f(x)=x²-4x-5 is the polynomial function of the given graph.
What is Polynomial?Polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables
We need to find the polynomial of the given graph.
Graph is a mathematical representation of a network and it describes the relationship between lines and points.
When x=0, then y should be -5.
This can be satisfied by f(x)=x²-4x-5 and f(x)=-x²-4x-5
Now let us find the value of y when x is 2.
When x is 2 the value of y should be -9 by the given graph
f(x)=x²-4x-5
=4-8-5
=-9
Hence, f(x)=x²-4x-5 is the polynomial function of the given graph.
