Answer:
Step-by-step explanation:
C = 147 ft. The relevant formula is C = 2(pi)r, and here C = 147 ft = 2(pi)r.
The relevant area formula is A = (pi)r^2. If we solve the above formula for r we get
147 ft
r = ------------ and so r^2 (needed to calculate the area) is
2pi
147^2 ft^2
r^2 = ------------------
4(pi)
147^2 ft^2
and so the area is A = ---------------- = 7203/pi
3 pi
C C^2
Alternative method: C = 2pi*r so r = -------------- and r^2 = -------------
2 pi 4pi^2
C^2 C^2
then the area of the circle is A = pi(r^2) or pi*-------------- = ---------------
4pi^2 4pi
(147 ft)^2
and in this case the area of the circle is A = --------------
4 pi
or A = 1720 ft^2
What is meant by the order of operations?
Answer:
Step-by-step explanation: The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Please help me please please ASAP ASAP please ASAP
Answer:
45Step-by-step explanation:
Well, it is not 90 degrees, as it is not a right angle.
It cannot be 180 degrees as that would be a straight line and a triangle's whole angle measure is 180 degrees.
It is an acute angle, and appears to be half of 90 degrees, so I would have to say 45 degrees.
Not enough information is false because you can infer that it is 45 degrees by looking at it.
Hope that helps!

What would be the best estimate for the height of a front door?
Answer: The height of a standard door is about 2 m. The length of an adult pace is about 1 m. The length of a size 8 shoe is about 30 cm. Most adults are between 1.5 m and 1.8 m in height.
Step-by-step explanation:
i f N(-7,-1) is a point on the terminal side of ∅ in standard form, find the exact values of the trigonometric functions of ∅.
Answer:
[tex]sin\ \varnothing = \frac{-1}{10}\sqrt 2[/tex]
[tex]cos\ \varnothing = \frac{-7}{10}\sqrt 2[/tex]
[tex]tan\ \varnothing = \frac{1}{7}[/tex]
[tex]cot\ \varnothing = 7[/tex]
[tex]sec\ \varnothing = \frac{-5}{7}\sqrt 2[/tex]
[tex]csc\ \varnothing = -5\sqrt 2[/tex]
Step-by-step explanation:
Given
[tex]N = (-7,-1)[/tex] --- terminal side of [tex]\varnothing[/tex]
Required
Determine the values of trigonometric functions of [tex]\varnothing[/tex].
For [tex]\varnothing[/tex], the trigonometry ratios are:
[tex]sin\ \varnothing = \frac{y}{r}[/tex] [tex]cos\ \varnothing = \frac{x}{r}[/tex] [tex]tan\ \varnothing = \frac{y}{x}[/tex]
[tex]cot\ \varnothing = \frac{x}{y}[/tex] [tex]sec\ \varnothing = \frac{r}{x}[/tex] [tex]csc\ \varnothing = \frac{r}{y}[/tex]
Where:
[tex]r^2 = x^2 + y^2[/tex]
[tex]r = \sqrt{x^2 + y^2[/tex]
In [tex]N = (-7,-1)[/tex]
[tex]x = -7[/tex] and [tex]y = -1[/tex]
So:
[tex]r = \sqrt{(-7)^2 + (-1)^2[/tex]
[tex]r = \sqrt{50[/tex]
[tex]r = \sqrt{25 * 2[/tex]
[tex]r = \sqrt{25} * \sqrt 2[/tex]
[tex]r = 5 * \sqrt 2[/tex]
[tex]r = 5 \sqrt 2[/tex]
Solving the trigonometry functions
[tex]sin\ \varnothing = \frac{y}{r}[/tex]
[tex]sin\ \varnothing = \frac{-1}{5\sqrt 2}[/tex]
Rationalize:
[tex]sin\ \varnothing = \frac{-1}{5\sqrt 2} * \frac{\sqrt 2}{\sqrt 2}[/tex]
[tex]sin\ \varnothing = \frac{-\sqrt 2}{5*2}[/tex]
[tex]sin\ \varnothing = \frac{-\sqrt 2}{10}[/tex]
[tex]sin\ \varnothing = \frac{-1}{10}\sqrt 2[/tex]
[tex]cos\ \varnothing = \frac{x}{r}[/tex]
[tex]cos\ \varnothing = \frac{-7}{5\sqrt 2}[/tex]
Rationalize
[tex]cos\ \varnothing = \frac{-7}{5\sqrt 2} * \frac{\sqrt 2}{\sqrt 2}[/tex]
[tex]cos\ \varnothing = \frac{-7*\sqrt 2}{5*2}[/tex]
[tex]cos\ \varnothing = \frac{-7\sqrt 2}{10}[/tex]
[tex]cos\ \varnothing = \frac{-7}{10}\sqrt 2[/tex]
[tex]tan\ \varnothing = \frac{y}{x}[/tex]
[tex]tan\ \varnothing = \frac{-1}{-7}[/tex]
[tex]tan\ \varnothing = \frac{1}{7}[/tex]
[tex]cot\ \varnothing = \frac{x}{y}[/tex]
[tex]cot\ \varnothing = \frac{-7}{-1}[/tex]
[tex]cot\ \varnothing = 7[/tex]
[tex]sec\ \varnothing = \frac{r}{x}[/tex]
[tex]sec\ \varnothing = \frac{5\sqrt 2}{-7}[/tex]
[tex]sec\ \varnothing = \frac{-5}{7}\sqrt 2[/tex]
[tex]csc\ \varnothing = \frac{r}{y}[/tex]
[tex]csc\ \varnothing = \frac{5\sqrt 2}{-1}[/tex]
[tex]csc\ \varnothing = -5\sqrt 2[/tex]

What is the slope-intercept equation for the line below?
Answer:
Answer is C
Step-by-step explanation:
A quartic polynomial P(x) has rational coefficients. If 2 − i and-√5 are roots of P(x) = 0, what are the other 2 roots?
Answer:
2 + i and + √5
Step-by-step explanation:
Since P(x) is a quartic equation, it has 4 roots.
Since 2 - i and -√5 are two of its roots, then its conjugate pairs of 2 + i and + √5 are its other two roots.
So, its other two roots are 2 + i and + √5

CAN SOMEONE PLEASE GIVE ME THE ANSWER TO QUESTION 6? PLS ILY
Answer:
12.5
Step-by-step explanation:
We want to find 1/8 of 100 so we would write it as 100÷8 to get 12.5
Now we know that 12.5 is equivalent to 1/8 but let's double check.
12.5×8 is 100
1/8 ×8 is 8/8
100=8/8

Step-by-step explanation:
find the area of the semicircle (1/2 circle with a diameter of 10)
Answer:
39.25 unit²
Step-by-step explanation:
Radius of circle = diameter/2 = 10/2 = 5
Area of a circle = πr²
Area of ½ circle = ½ πr² = ½ x (22/7) x 5²
Area = 39.25 unit^2
Find the volume of the cone-
Answer:
12.6ft³
Step-by-step explanation:
Hey There!
So the first thing we need to do is find the formula for volume of a cone
[tex]V=\pi r^{2} \frac{h}{3}[/tex]
r = radius
h = hypotenuse
Now all we have to do is plug in the hypotenuse and the radius
[tex]V=\pi 2^{2} \frac{3}{3}[/tex]
2²=4
[tex]\frac{3}{3} =1[/tex]
4xπ=12.5663706144
And now we just round to the nearest tenth
so we can conclude that the volume of the cone is 12.6ft³

. Solve for x
10 = 5(x + 8)
Answer:
x = -6
Step-by-step explanation:
10 = 5(x+8)
=> 5(x+8) = 10
=> 5x + 40 = 10
=> 5x = 10 - 40
=> 5x = -30
=> x = -30/5
=> x = -6

A mountain climber ascends a mountain to its peak. The peak is 14,090 ft above sea level. The climber then descends 490 ft to meet a fellow climber. Find the climber’s elevation above sea level after meeting the other climber.
13,600 ft
14,580 ft
–13,600 ft
9,190 ft
Answer:
13,600 feet above sea level
Step-by-step explanation:
The climber was at 14,090 feet above sea level, and then they went 490 feet closer to sea level to meet the other climber. Since they’re moving closer to sea level and you want to know how far *above* sea level they are, subtract 490 from 14,090. 14,090-490=13,600 feet above sea level
0.6x + 2.7 = 0.9x
"solve the equation. show all your steps"
Answer:
x=9
Step-by-step explanation:
0.6x+2.7=0.9x
move the terms
0.6x-0.9x=-2.7
collect like terms
-0.3x=-2.7
divide both sides
x=9

For what value of x is the rational expression below equal to zero?
(x+5)(x - 1)
A. 4
ОО
B. 1
C. -5
d
D. -4
SUBMIT
Answer:
I can only guess that by x^2-2x-24 you mean the entire denominator. In cases like this is is important to use parentheses to remove any doubts. For example:
(x+8) / (x^2-2x-24).
This rational expression is undefined at any x for which the denominator, x^2-2x-24, is zero.
x^2-2x-24 factors into (x+4)(x-6). The roots are -4 and +6.
Thus, the given expression is undefined at {-4,6} (set notation).
