Answer:
It is 30°
Step-by-step explanation:
Putting the formula exterior angle of a triangle = the sum of 2 interior angles of a triangle.
let the angle be x;
Therefore,
80°+x = 110°
x = ( 110 - 80 )°
x = 30°

Find the equation of the exponential function represented by the table below:
Answers
Answer:
x=2
Step-by-step explanation:
In the table the ratio of x to y in the first one is 0:2 and ongoing.
Answer:
\(f\left(x\right)=\ 2\left(2\right)^{x}\)
Step-by-step explanation:
Step 1: Make a equation, f(x)= ab^x.
A is the y value, whenever the x value is zero. So, a is 2.
Lets put that in our equation:
f(x)= 2b^x.
B is the common ratio on the y values. When you follow the pattern, 2, 4, 8, 16, you realize that the common ratio is 2. 2*2 is 4, 4*2, is 8, 8*2 is 16, and so on. So the common ratio is 2.
Lets go ahead and add that to our equation:
f(x)= 2(2)^x.
There is no more steps in this process, so that is actually your final answer:
\(f\left(x\right)=\ 2\left(2\right)^{x}\)

What is an absolute value function?We know the absolute value function of the modulus function always outputs a positive value irrespective of the sign of the input.
In piecewise terms | x | = x for x ≥ 0 and | x | = - x for x < 0.
We know, If |x| ≤ a, Then x ≤ a and x ≥ - a.
The given situation is modeled by the modulus inequality |x - 60| ≤ 3.
Therefore, (x - 60) ≤ 3 and (x - 60) ≥ - 3.
x ≤ 63 and x ≥ 57.
So, The acceptable speed(x) is between, 57 ≤ x ≤ 63.

A right angle is shown divided in two parts. The measure of the angle of one part is 50 degrees and the measure of the other part is 5x plus 15 degrees.
a 5
b 7
c 11
d 15
Answers
Answer: a. 5
Since the angle is right, we know it is equal to 90 degrees.
Using the information provided, we can set up an equation.
50 + 5x + 15 = 90
Simplifying the equation, we get:
5x + 65 = 90
Subtracting 65 from both sides, we get:
5x = 25
Dividing both sides by 5, we get:
x = 5

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
Answers
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answers
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.

the answer is y=5+4x
Step-by-step explanation:

A composite figure has a radius of 10 cm.
A circle with radius of 10 centimeters. One-quarter of the circle is cut out of the figure.
What is the area of this composite figure? Use 3.14 for Pi.
23.55 centimeters squared
78.5 centimeters squared
235.5 centimeters squared
314 centimeters squared
Answers
Answer:
C, 235.5 cm^2
Step-by-step explanation:
Formula for area of circle:
A = πr^2
Where π represents pi(3.14 or 22/7) and r represents the radius.
Plug in given value (10):
A = πr^2
A = 3.14(10)^2
A = 3.14(100)
A = 314
Now they say a quarter of this circle is cut out, which means we have to first find out what a quarter of this area is:
314/4
= 78.5
A quarter of this circle is 78.5, so let's subtract this from the total area (314):
314 - 78.5
= 235.5 cm^2
The area is 235.5 centimeters squared.
A scale model of the U.S. National Monument is 10 inches tall. The actual monument is 100 feet tall. Write a scale using the same units on both sides. Example: 1cm = 100cm. (remember, there are 12 inches in 1 foot)
Answers
Answer:
The height of the scale model is 10 inches, and the height of the actual monument is 100 feet. Since there are 12 inches in 1 foot, we can convert the height of the actual monument to inches:
100 feet × 12 inches/foot = 1200 inches
Now we can write the scale as:
1 inch : 120 feet
This means that one inch on the scale model represents 120 feet of the actual monument.
