the diameter of a circle is 8 ft. Find the circumferenceto the nearest tenth.
Answer:
25.1 ft
Step-by-step explanation:
To solve for circumference is pretty simple. Just use the equation 2pi r (r=radius, radius is diameter divided by 2).
So essentially, apply to your calculator:
2(3.14)4=25.12
pretty simple! hope this helps!

What is the equation of the midline for the function f(x)? f(x)=1/2cos(x)+5
Answer: y=5
Step-by-step explanation:
At x = 0 and y = 5.5 the equation of the midline for the function
[tex]f(x)= \frac{1}{2} cos(x)+5[/tex] .
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. For example, 3x – 5 = 16 is an equation.
Is the cos graph symmetrical?
The function cos x is even, so its graph is symmetric about the y-axis.
According to the question
[tex]f(x)= \frac{1}{2} cos(x)+5[/tex]
as cos x is symmetric about y axis
So,
By plotting the graph
we can see that at point x = 0
y = 5.5 is the mid point of this equation
Hence, x = 0 and y = 5.5 the equation of the midline for the function
[tex]f(x)= \frac{1}{2} cos(x)+5[/tex] .

Answer:
9/32
Step-by-step explanation:
Given
Fraction of the cake that was was left over = 3/8
If 3/4 of the left over was eaten, the ffraction eaten is expressed as;
Fraction eaten = 3/4 of 3/8
Fraction eaten = 9/32
hence Noma ate 9/32 of the whole cake
Make 'y' the subject of the equation. x = 2y -7
Answer:
y = (x + 7)/2
here's your solution
=>. it is given. x = 2y - 7
=> we have to make y as subject
=> now, we can writ this equation in this way
=> 2y - 7 = x
=> now put all constant to right side
=> 2y = x +7
=>. y = x+ 7 /2
hope it helps

Step-by-step explanation:
The angle between a tangent and the radius at the point of contact is 90° , so
Δ ABC is a right triangle at ∠ B
Using Pythagoras' identity in the right triangle
x² + 7² = 18²
x² + 49 = 324 ( subtract 49 from both sides )
x² = 275 ( take the square root of both sides )
x = [tex]\sqrt{275}[/tex] ≈ 16.6 ( to the nearest tenth )

∠A and \angle B∠B are supplementary angles. If m\angle A=(7x+24)^{\circ}∠A=(7x+24) ∘ and m\angle B=(7x-26)^{\circ}∠B=(7x−26) ∘ , then find the measure of \angle A∠A.
Answer:
115degrees
Step-by-step explanation:
Given the following angles
m<A=(7x+24)°
m<B=(7x-26)°
Since both angles are supplementary, their sum will be 180 degrees
Taking the sum of the angles
m<A + m<B = 180
7x+24 + 7x - 26 = 180
14x - 2 = 180
14x = 180+2
14x = 182
x = 182/14
x = 13
get m<A
m<A = 7x+24
m<A = 7(13) + 24
m<A = 91 + 24
m<A = 115
Hence the measure of angle m<A is 115degrees

write the standard form equation of the circle( 7,-5)
Answer:
(x-7)²+(y+5)²=25
Step-by-step explanation:
The standard form of a circle is (x-h)²+(y-k)²=r²
(h,k) is the center
r is the radius
h=7
k=-5
r=5
(x-7)²+(y--5)²=5²
(x-7)²+(y+5)²=25

Step-by-step explanation:
are these lines parallel, perpendicular, or neither?
Answer:
[tex]\Huge\boxed{neither}[/tex]
Step-by-step explanation:
Parallel lines never touch and these lines intersect therefore these are not parallel lines
These lines may intersect but they do not create 90 degree angles which is essential for perpendicular lines and for those reasons the lines shown are not perpendicular lines
So we conclude that the lines shown are neither parallel lines nor perpendicular lines

You toss two number cubes. If a sum of 7 or 11 comes up, you get 7 points, if not you lose 2 points.
The probabilities for each of the sums is:
P(2) = 1/36 P(3) = 1/18 P(4) = 1/12 P(5) = 1/9
P(6) = 5/36 P(7) = 1/6 P(8) = 5/36 P(9) = 1/9
P(10) = 1/12 P(11) = 1/18 P(12) = 1/36
The probability of a sum of 7 or 11 is:
1/36
Answer:
2/9Step-by-step explanation:
The probability of a sum of 7 or 11 is the sum of each probability:
P(sum of 7 or 11) = P(7) + P(11) = 1/6 + 1/18 = 3/18 + 1/18 = 4/18 = 2/9Answer:
the first part is 2 / 9
the second part is 0

A volleyball team played five games. In those games, the team won by 7 points, lost by 3, lost by 2, won by 4, and won by 9. What was the total amount of points from all five games
Answer:
The answer is "3"
Step-by-step explanation:
In essence, it represents the sum of all comments divided by the number of responses.
It implies scoring in the five games corresponds to a total of five results.
Scores :
7 points implies+ 7
lost by 3 implies- 3
lost by 2 implies - 2
won by 4 implies + 4
won by 9 implies + 9
Sum of all scores [tex]= 7 - 3 - 2 + 4 + 9 = 15[/tex]therefore
Its team has a total of 5 games[tex]= 5[/tex]
Measurement in scores in five games thus = sum of all scores/sum with the team played games [tex]=\frac{15}{5}= 3[/tex]
