Answer:
9. b) 3.14 m²
10. d) 36.98 cm²
Step-by-step explanation:
9: Area of circle: πr²
one fourth of a circle, so its 1/4πr²
1/4*3.14*2²
1/4*3.14*4
3.14
10.
Diameter is 4.3 so the width of rectangle is 4.3
both circle has diameter of 4.3 so the length is 4.3*2 = 8.6
Area - L x W
4.3*8.6
= 36.98

Answer:
80.38°
Step-by-step explanation:
The relevant trig relation is ...
Tan = Opposite/Adjacent
The person is standing 40 ft from the building. The point they're looking at is 236 ft above their eyes. So the angle α is found from ...

from a point 1.75 m above the ground and 10 m away from a tower the angle of elevation of a top of a tower is 60 degree calculate the height of the tower
Answers
Answer:
17.32 meters
Step-by-step explanation:
Let’s call the height of the tower H. The distance from the point to the base of the tower is 10 m. The angle of elevation from the point to the top of the tower is 60 degrees.
Using trigonometry, we can calculate that:
tan (60) = H / 10
H = 10 * tan (60)
H = 10 * √3
H = 17.32 m
Therefore, the height of the tower is 17.32 meters.

Answers
ANSWER
f(x) = 6x - 17
EXPLANATION
The equation of a line with slope m and y-intercept b is:
\(f(x)=mx+b\)We know the slope of this line, m = 6, so we have this equation:
\(f(x)=6x+b\)To find the y-intercept we have to replace f and x with the given point: f(3) = 1:
\(\begin{gathered} 1=6\cdot3+b \\ 1=18+b \\ b=1-18 \\ b=-17 \end{gathered}\)The equation is:

Answers
Answer:
15 km/h
Step-by-step explanation:
Leo takes 15 minutes to cycle to school at an average speed of 12 km/h. What speed will he have if he only takes 12 minutes?
15 minutes * (1 hour)/(60 minutes) = 0.25 hour
speed = distance/time
distance = speed * time
distance = 12 km/h * 0.25 hour = 3 km
He cycles a distance of 3 km.
12 minutes * (1 hour)/(60 minutes) = 0.2 hour
speed = distance/time
speed = 3 km/(0.2 hour)
speed = 15 km/h

Answers:
a) 32500
b) 0.00604
c) 2.4 * 10^6
d) 1.47 * 10^(-3)
===================================================
Explanation:
The exponent over the 10 tells us how many spaces to move right or left. If the exponent is positive, we move right. If negative, we move left. Think of a number line.
For part (a), the exponent is 4. So we move the decimal point 4 spaces to the right.
The 3.25 then becomes 32500
--------------
In part (b), the exponent -3 means we move 3 spots to the left to go from 6.04 to 0.00604
---------------
Part (c)
Place the decimal point between the first two digits and erase the zeros to get 2.4
Then we need to move the decimal point 6 spots to the right to get back to 2,400,000 again
Therefore we can say 2,400,000 = 2.4*10^6
---------------
Part (d)
Place the decimal point just after the first nonzero digit, and erase the zeros to the left to get 1.47
We must move the decimal point 3 spots to the left to go from 1.47 back to 0.00147 again
It means 0.00147 = 1.47*10^(-3)

Now, We can simplify as;
⇒ sin (x + 10)° = cos (4x - 4)°
⇒ cos (90 - (x + 10))° = cos (x - 4)°
⇒ 90 - (x + 10) = x - 4
⇒ 90 - x - 10 = x - 4

Find the mean, median mode(s), range, standard deviation, and variance of the data: Which measure of central tendency best represents the data
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given tbe data :
21, 15, 16, 25, 13, 18 5, 3, 2, 6, 5, 2, 5
Ordered data : 2, 2, 3, 5, 5, 5, 6, 13, 15, 16, 18, 21, 25
Mean, m = Σx /n
Σx = 136
n = sample size = 13
m = Σx / n = 136 / 13 = 10.46
Mode, = 5 (most frequently occurring with frequency of 5)
Median = 1/2(n+1)th term = 1/2(14) = 7th term = 6
Range = maximum - minimum = [25 - 2] = 23
Variance : (V) = Σ(x - m)²/n-1
V = [(2-10.46)^2 + (2-10.46)^2 + (3-10.46)^2 + (5-10.46)^2 + (5-10.46)^2 + (5-10.46)^2 + (6-10.46)^2 + (13-10.46)^2 + (15-10.46)^2 + (16-10.46)^2 + (18-10.46)^2 + (21-10.46)^2 + (25-10.46)^2] / (13-1)
= 745.2308 / 12
= 62.10
Standard deviation = sqrt(V) = sqrt(62.10) = 7.88

X : 6, 45, 52, 43, 48, 41, 50, 48
Reordered data, X: 6, 41, 43, 45, 48, 48, 50, 52
Mean, m = Σx /n
Σx = 333
n = sample size = 8
m = Σx / n = 333 / 8 = 41.625
Median = 1/2 (n+1)th term = 46.5
Range = 52 - 6 = 46
Mode = 48 (highest occurring frequency of 2)
Variance (V) = Σ(x - m)²/n-1
V = [(6-41.625)^2 + (41-41.625)^2 + (43-41.625)^2 + (45-41.625)^2 + (48-41.626)^2 + (48-41.625)^2 + (50-41.625)^2 + (52-41.625)^2] / 5
= 1541.862251 / 7

Standard deviation = sqrt(Variance)
Standard deviation = sqrt(220.26603)

A corporation creates a sinking fund in order to have $900,000 to replace some machinery in 10 years. How much should be placed in this account at the end of each month if the annual interest rate is 3.8% compounded monthly? (Round your answers to the nearest cent.) How much interest was earned during the third month of the 7th year?
Answers
The interest earned during the third month of the 7th year is $3,613.55.
What is interest rate?
The amount of interest due each period expressed as a percentage of the amount lent, deposited, or borrowed is known as an interest rate.
Let PMT be the monthly payment, r be the monthly interest rate, and n be the total number of payments. Then:
FV = PMT × [(1 + r)n - 1]/r
In this case, we want to find PMT, given that FV = $900,000, r = 0.038/12, and n = 10 × 12 = 120:
\($900,000 = PMT * {[(1 + 0.038/12)}^{120} - 1]/(0.038/12)\)
Solving for PMT, we get:
PMT = $682.48
\(FV = $682.48 * [(1 + 0.038/12)^87 - 1]/(0.038/12)\\\\ = $89,324.47\\\\PV = $682.48 * [(1 + 0.038/12)^83 - 1]/(0.038/12) \\\\= $85,710.92\)
The interest earned during the third month of the 7th year is:
$89,324.47 - $85,710.92 = $3,613.55
Therefore, the interest earned during the third month of the 7th year is $3,613.55.

what is between fractions 6/6 and 6/7
Answers
The fraction 13/7 lies between the fractions 6/6 and 6/7.
We have,
Between the fractions 6/6 and 6/7, there are infinitely many fractions.
To find a fraction that lies between these two fractions, we can take their average.
The fraction 6/6 simplifies to 1, and the fraction 6/7 cannot be simplified further.
To find the average, we add the two fractions and divide the sum by 2:
(6/6 + 6/7) / 2
To add the fractions, we need a common denominator, which is the least common multiple (LCM) of 6 and 7, which is 42.
Converting the fractions to have a common denominator:
(6/6) x (7/7) + (6/7) x (6/6) / 2
Simplifying the expression:
(42/42 + 36/42) / 2
Combining the numerators:
(78/42) / 2
Dividing:
78/42 = 13/7

Step-by-step explanation:
Answer:

Step-by-step explanation:
Firstly, distrubute 2 to our parentheses (2x - 10). Now, let's add our like terms, 2x - 10 = 4x + 6 since x alone is one we add this to 3x, equaling 4x. Then we're going to move our variable and sign, 2x - 10 - 4x = 6. Alright, now combine like terms and calculate (2x - 4x), we know when we subtract two and four, it's a negative 2, -2x = 6 + 10 = 16. Now divide both sides of the equation by -2, 16 divided by -2 is -8. Therefore, x = -8, hope this helped! Have a great day!

11-9y=-38 then you want to move -38 to the other side, and when you move it to the other side it changes its value then from -38 it becomes 38. Same for the -9y, we move it to the other side and it changes its value so now from -9y its 9y.
