In a right triangle, the length of one leg is 7 ft. The length of the other leg is 10 ft. What is the length of the hypotenuse?
Final answer:
To find the length of the hypotenuse in a right triangle with legs of 7 ft and 10 ft, we use the Pythagorean theorem, resulting in a hypotenuse of approximately 12.21 feet.
Explanation:
The student is asking about the length of the hypotenuse in a right triangle where one leg is 7 ft and the other is 10 ft. To find the hypotenuse, we use the Pythagorean theorem which states a² + b² = c², where a and b are the lengths of the legs of the triangle, and c is the length of the hypotenuse.
For this triangle, the calculations would be:
a² = 7² = 49
b² = 10² = 100
a² + b² = c²
49 + 100 = c²
149 = c²
c = [tex]\sqrt{149[/tex]
c = 12.21 ft (rounded to two decimal places)
Therefore, the length of the hypotenuse of the triangle is approximately 12.21 feet.
f(x)=x^2+10 What is the average rate of change of F over the interval [-2,-1]
Answer: -3
Step-by-step explanation: plug -2 into f(x)=x^2+10 and you get 14, then plug the -1 into that same equation and end up with 11, now you subtract the 11 from the 14 and get 3 but since you subtracted or in other words the number decreased it would be -3
The average rate of change of f(x) over the interval [-2,-1] is 3.
Explanation:To find the average rate of change of f(x) over the interval [-2,-1], we need to calculate the difference in the function values at the endpoints and divide it by the difference in the x-values. Let's substitute the endpoints into the function:
f(-2) = (-2)² + 10 = 4 + 10 = 14
f(-1) = (-1)² + 10 = 1 + 10 = 11
The difference in function values is 14 - 11 = 3, and the difference in x-values is -1 - (-2) = -1 + 2 = 1. Therefore, the average rate of change is 3/1 = 3.

Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah a total of 11 people took the trip. She was
able to purchase coach tickets for $330 and first class tickets for $1110. She used her total budget for airfare for the trip, which was $8310. How many first class
tickets did she buy? How many coach tickets did she buy?
number of first class tickets bought
Answer: 8 First class tickets
Step-by-step explanation:
You can set up a system of equations for this problem. Let x = number of coach tickets and y = number of first class tickets. Then:
330x + 1220y = 12730 (cost of coach tickets plus cost of first class tickets is total budget)
x + y = 17 (number of coach tickets plus number of first class tickets is total number of people)
Solve the second equation for y to get y = 17 - x, then plug that into the first equation and solve for x:
330x + 1220(17 - x) = 12730
330x + 20740 - 1220x = 12730
-890x + 20740 = 12730
-890x = -8010
x = 9
Sarah bought x = 9 coach tickets. Plug that into the second equation and solve for y:
9 + y = 17
y = 8
Sarah bought y = 8 first class tickets.

6 first class 5 coach

What is the area of a circle with a diameter of 16.2 in.?
Use 3.14 for pi and round your final answer to the nearest hundredth.
Enter your answer in the box.
In 2
Answer
206.02
Step-by-step explanation:
r=d/2
=16.2/2=8.1
3.12*8.1*8.1=206.0154
to the nearest hundred=206.02
The area of the circle with a diameter of 16.2 inches is approximately 206.24 square inches.
Explanation:The area of a circle can be found using the formula A = πr^2, where π represents the mathematical constant pi and r is the radius of the circle. Since the diameter of the circle is given as 16.2 inches, we can find the radius by dividing the diameter by 2: r = 16.2 / 2 = 8.1 inches. Now we can plug in this value into the formula to find the area: A = 3.14 * (8.1)^2 = 206.2446 square inches. Rounding this to the nearest hundredth, the area of the circle is approximately 206.24 square inches.

Cooper has $40 to spend and must buy a minimum of 18 cupcakes and donuts altogether. If Cooper decided to buy 7 cupcakes, determine the maximum number of donuts that he could buy.
Answer:15
15
7 cupcakes=17.5
40-17.5=22.5
donuts are 1.50
22.5 divided by 1.5 is 15
The maximum number of donuts Cooper can buy is 15.
Given that, the cost of cupcakes = $2.50 and the cost of donuts = $1.50.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Let the number of cupcakes be x and the number of donuts be y.
Cooper wans to buy a minimum of 18 cupcakes and donuts altogether
That is, x+y≥18
Cooper has $40 to spend on cupcakes and donuts.
So, 2.50x+1.50y≤40
Cooper decided to buy 7 cupcakes
Then number of donuts will be
2.50(7)+1.50y≤40
⇒17.5+1.50y≤40
Subtract 17.5 on both the sides of a inequality, we get
17.5+1.50y-17.50≤40-17.50
⇒1.50y≤22.5
Divide 1.50 on both the sides of a inequality, we get
1.50y/1.50≤22.5/1.50
⇒y≤15
Therefore, the maximum number of donuts Cooper can buy is 15.

What is the sum of all the exterior angles of a regular polygon?For a regular polygon of any number of sides, the sum of its exterior angle is 360° (full angle).
Exterior angle is an measure of rotation between one extended side(we extend it virtually) of the polygon with its adjacent side which is not extended.Consider that it be having 'n' sides, all the exterior angles are of same measure, and therefore, their measure is (360/n)°.
We are given that;
The 3 lines intersect and form 6 angles.
Now,
To find angle c, we need to use the fact that the angles around a point add up to 360 degrees. The six angles formed by the three intersecting lines include all the angles around a point, so we have to set up another equation;
Angle c + 48 degrees + 42 degrees + 90 degrees + 48 degrees + 42 degrees = 360 degrees
Simplifying and solving for angle c, we get:
Angle c = 360 degrees - 270 degrees
Angle c = 90 degrees
Therefore, by interior and exterior angles the measure of angle c is 90 degrees.

h(x)=x-4 what’s is the domain of h?
Answer:
all real number
Step-by-step explanation:
since h(x) is polynomial function
Final answer:
The domain of the function h(x)=x-4 is all real numbers, as there are no restrictions on the value of x.
Explanation:
The domain of a function represents all the possible values that can be input into the function. For the function h(x)=x-4, there are no restrictions on the value of x, since x represents a real number and there are no denominators or square roots to consider.
Therefore, the function h(x)=x-4 is defined for all real numbers, making the domain of h to be all real numbers, which is often denoted by the symbol (-∞, +∞) or simply written as 'all real numbers'.

A farmer has a square lot that is 200 feet on each side. She has a very powerful sprinkler that sprays water in a circle she doesn’t want to waste any water, so she’ll set her sprinkler so that it doesn’t spray any water outside of her lot. What is the largest percentage of her lot that she can water? (Answer to the nearest percent)
Answer:
78.5%
Step-by-step explanation:
Area of a 100ft radius circle = 628sqm
Area of rectangle = 800sqm
= 172sqm difference in size
if 800 sqm = 100%
Then 600 sqm = 3/4 = 75%
60sqm =3/40 = 7.5%
6sq m =3/400 =0.75%
2 sq m = 0.25%
30sqm = 1/2 of 7.5%= 3.75
3.75-0.25 = 3.50%
3.50% + 75 = 78.5%

A) 45°
B) 55°
C) 70°
D) 80°
A. 45 is your answer
The third angle is 45°.
Option A is the correct answer.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
The two angles in the triangle are 80 and 55.

The sum of all the angles in the triangle is 180.
Third angle = x
So,
80 + 55 + x = 180
135 + x = 180
Subtract 135 on both sides.
x = 180 - 135
x = 45

In the equation (x-3)2+(4+4)2=121, the radius of the circle is
Answer: The radius of the circle in 11
Final answer:
The equation is in the standard form (x - h)² + (y - k)² = r², where r is the radius. Thus, the square root of the constant term 121 would give the radius, which is 11.
Explanation:
To find the radius from an equation of a circle in the form (x - h)² + (y - k)² = r², where (h, k) is the center of the circle, and r is the radius, we need to compare it to the given equation.
As per the standard form, the number on the right side of the equation is r², the square of the radius.
We have (x - 3)² + (4 + 4)² = 121, which can be written as (x - 3)² + (8 - 0)² = 121, considering (3,0) as the center of the circle, the radius would be the square root of 121, which is 11.
