The drawing below represents a 22-foot ladder with its base placed 10 feet from the bottom of a vertical wall. whatis the best value for x
Answer:
x = 62.96°
Step-by-step explanation:
From the attached figure,
Base, b = 10 ft
Hypotenuse, H = 22 ft
We need to find the value of x. We can use trigonometry to find it.
We know that,
[tex]\cos\theta=\dfrac{B}{H}[/tex]
Putting all the values,
[tex]\cos x=\dfrac{10}{22}\\\\x=62.96^{\circ}[/tex]
So, the value of x is 62.96°.

In a certain year, the average e-mail user sent or received 111 e-mails each day. The number of e-mails received was 3 more than twice the number
sent. How many were sent and how many were received each day?
Answer:
Number of sent mail = 36
Number of received mail = 75
Step-by-step explanation:
Let,
x be the number of mails sent
y be the number of mails received
According to given statement;
x + y = 111 Eqn 1
y = 2x + 3 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
x + 2x + 3 = 111
3x = 111 - 3
3x = 108
Dividing both sides by 3
[tex]\frac{3x}{3}=\frac{108}{3}\\x = 36[/tex]
Putting x = 36 in Eqn 2
y = 2(36) + 3
y = 72 + 3 = 75
Hence,
Number of sent mail = 36
Number of received mail = 75

Find the area of the isosceles triangle.
13 cm is the side length
10 cm is the base length
what is the hight?
and area?
Answer:
Step-by-step explanation:
As we know that,
Area of isosceles triangle= 1/2 *b*h
we have a=10 and other side = hypotenuse=b=13 cm
Now e have formula to find h,
h=[tex]\sqrt{b^{2} -a^{2}/4}[/tex]
now putt the values ,
we get,
h=[tex]\sqrt{169-100/4}[/tex]
h=[tex]\sqrt{576/4}[/tex]
h=12 cm height of isosceles triangle ,Area = 1/2 * b*h
Area=1/2*13*12
Area=S=60[tex]cm^{2}[/tex]Original Price = ? Percent of Discount = 5% Sale Price = $57
Answer:
$60
Step-by-step explanation:
100 - 5 = 95%
95% = 57
divide both sides by 95 to find 1%
1% = 0.6
multiply both sides by 100 to find 100%
100% = 60

for all positive values of x the value of ^log x ^x is always __ and the value of ^log x ^1 is always__
Answer: 1, 0
Step-by-step explanation: Logarithm base x of x is 1 and Logarithm base x of 1 is 0.
The positive values of x so here the value of [tex]log x ^x[/tex] should always be 1 and the value of [tex]log x ^1[/tex] should be 0 .
What is a Logarithm base?It is the function where the log , base a of the x. It shows the inverse of the exponential function so here the exponential form be used.
So we can conclude that The positive values of x so here the value of [tex]log x ^x[/tex] should always be 1 and the value of [tex]log x ^1[/tex] should be 0 .
Hence, the above answers are correct.

How can you use inverse operations to solve equations with
addition and subtraction?
(make the answer on the simpler side please)
Answer & Step-by-step explanation:
You can check your answer easily by using inverse operations. For example, if you're solving for 1+2, you can check it by subtraction. Since 1+2=3, you can subtract 3 by 1, and you come up with 2.

find the equation of the line that is parallel y= 2x+10 and passes through the point (6,-4)
Answer:
The equation of the parallel line to the given line
y = 2 x - 16
Step-by-step explanation:
Step(i):-
Given equation of the straight line y = 2 x +10
2x - y + 10 =0
The equation of the parallel line to the given line is
a x + by + k=0
The equation of the parallel line to the given line is
2x - y + k=0
Step(ii):-
Given point ( 6,-4)
The equation of the parallel line to the given line is
2x - y + k=0
This line passing through the point ( 6,-4)
2(6) - (-4)+ k=0
12 + 4 +k =0
16 + k=0
k = -16
Final answer:-
The equation of the parallel line to the given line
y = 2 x - 16
