Answer:
about 23.0979
Step-by-step explanation:
tan 57 = n/15
multiply 15 on both sides ---> 15(tan 57) = n/15 (15)
n is about 23.0979
Write an equation for the circle
Given:
The graph of a circle.
To find:
The equation of the given circle.
Solution:
The standard form of a circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex] ...(i)
Where, (h,k) is vertex and r is the radius.
From the given graph it is clear that the radius of the circle is 4 units and the center of the circle is (-2,2).
Putting [tex]h=-2, k=2[/tex] and [tex]r=4[/tex] in (i), we get
[tex](x-(-2))^2+(y-(2))^2=(4)^2[/tex]
[tex](x+2)^2+(y-2)^2=16[/tex]
Therefore, the equation of the circle is [tex](x+2)^2+(y-2)^2=16[/tex].

SOMEONE PLEASE HELP ME WITH MATHHHH
Triangle Congruency please help!!
Answer:
A
Step-by-step explanation:
the nice thing about triangle is that the smallest angle is always opposite the smallest side, etc. also, we can get the remaining angle because we have 2 angles already and there are always 180 degrees in a triangle.
50+ 63= 113
180-113 =67
so, 50 is the smallest angle and thus the side opposite of it is the smallest. next is side bc because 63 is the next biggest angle measure. lastly, side ac is the largest because it's opposite of the largest angle measure
Answer:
a
Step-by-step explanation:
Find the equation of a line that passes through (2,9) and is parallel to the graph of y = 3x + 6. Write the equation in slope-intercept form, if possible.
Answer:
y = 3x + 3
Step-by-step explanation:
If two lines are parallel to each other, they have the same slope.
The first line is y = 3x + 6. Its slope is 3. A line parallel to this one will also have a slope of 3.
Plug this value (3) into your standard point-slope equation of y = mx + b.
y = 3x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (2, 9). Plug in the x and y values into the x and y of the standard equation.
9 = 3(2) + b
To find b, multiply the slope and the input of x (2)
9 = 6 + b
Now, subtract 6 from both sides to isolate b.
3 = b
Plug this into your standard equation.
y = 3x + 3
This equation is parallel to your given equation (y = 3x + 6) and contains point (2, 9)
Hope this helps!
What is the following product?

Find the function h(x) = f(x) + g(x) if f(x) = 4^x + 2 and g(x) = x - 4.
h( x) = 4 x + 1 -2
h( x) = 4 x + x + 6
h( x) = 4 x - 4
h( x) = 4 x + x - 2
Answer:
h( x) = 4^x + x - 2
Step-by-step explanation:
h(x)=f(x)+g(x)=4^x+2+x-4=4^x+x-2
In a right triangle, one acute angle is 22º and the hypotenuse is 70 cm. Find the
lengths of the legs and the other angle measure.
Answer:
Adjacent leg (In relation to the angle that is measure 22 degrees)= 70*Cosine 22 or 64.9; Opposite leg (In relation to the angle that is measure 22 degrees)=70* Sin 22 or 26.22
Step-by-step explanation:
The other angle measure is 90-22 or 68.
To find the length of the adjacent leg (a) use cosine. Remember cosine is Adjacent leg over hypotenuse.
Cosine 22= a/70- Multiply by 70
70* Cosine 22=a or about 64.9
To find the length of the opposite leg (o) use sine. Remember sine is Opposite leg over hypotenuse
Sine 22= o/70
70*Sine 22=o
o= about 26.22

15/3 = 45/x
solve for x
Answer:
15/3=45/x
We move all terms to the left:
15/3-(45/x)=0
Domain of the equation: x)!=0
x!=0/1
x!=0
x∈R
We add all the numbers together, and all the variables
-(+45/x)+15/3=0
We add all the numbers together, and all the variables
-(+45/x)+5=0
We get rid of parentheses
-45/x+5=0
We multiply all the terms by the denominator
5*x-45=0
We add all the numbers together, and all the variables
5x-45=0
We move all terms containing x to the left, all other terms to the right
5x=45
x=45/5
x=9

What's another way to define absolute value?
The opposite of a number
The multiplicative inverse of a number
The distance of a number from zero
a. n
The value of a number
Answer:
the distance of a number from zero
Step-by-step explanation:
in other words, it is the positive value of the number.
if the number is negative then the absolute value is the positive of it.
if the value is positive, then it is still positive.
The sum of b and its reciprocal
Answer:
(b^2+1)/b
Step-by-step explanation:
The reciprocal of b is written as 1/b
The sum of b and 1/b is expressed as;
b + 1/b
Sind the LCM
= b(b)+1/b
= (b^2+1)/b
Hence the sum of b and its reciprocal is (b^2+1)/b

Which of the following are not perfect squares? Select all that apply.
16
44
81
6
49
24
Answer and Step-by-step explanation:
44, 6, and 24 do not have perfect squares.
To be a perfect square, they have to be able to have a number that, when it multiplies itself by itself (needs to be a whole number), it turns into the bigger number.
44, 6, and 24 can't do this when being square rooted.
16 turns into 4.
81 turns into 9.
49 turns into 7.
#teamtrees #PAW (Plant And Water)
Answer:
44, 6, and 24
Step-by-step explanation:
4²=16 so it's a perfect square
9²=81 so it's a prefect square
7²=49 so it's a perfect square
44, 6, and 24 all result in decimals so it's not a perfect square.
Lucius sells jellyfish jam part-time. He is paid a monthly commission. He receives 30% of his first $900 in sales and 25% of the rest of his sales. Last month he sold $2,600 worth of jam. How much commission did he earn last month?
Answer:
695
Step-by-step explanation:
First I would septate the 900 from the 2600
2600-900=1700
Then I'll take both %s and turn them to decimal 25%-0.25 30%-0.30
I take the 900 times the 0.30 and the 0.25 times 1700
900x0.30=270
1700x0.25=425
then add them both together
270+425=695
