Answer:
x° = 47°
Step-by-step explanation:
The sum of the measurements of three interior Angles in a triangle is 180°.This is known as angle sum property.Same case is here.
78°,55° and x° are interior angles here.
So,
[tex] 78{}^{ \circ} + 55 {}^{ \circ} + x {}^{ \circ} = 180 {}^{ \circ} [/tex]Solving for x°,
[tex]133 {}^{ \circ} + x {}^{ \circ} = 180 {}^{ \circ} [/tex][tex]x {}^{ \circ} = 180 {}^{ \circ} - 133 {}^{ \circ} [/tex][tex]x {}^{ \circ} = \boxed{47 {}^{ \circ} }[/tex]Hence,the value of x° is 47°.

Explain how to find the average rage of change for a function over a given interval.
The average rate of change for a function over an interval is the slope
How to explain the steps?Take for instance, we have the function to be
Function f(x)
And the interval is (a,b)
The average rate of change for the function over the interval is
Rate = (f(b) - f(a))/(b - a)
The above represents the slope
Take for instance, we have:
f(x) = x^2 [2, 4]
We have:
f(2) = 2^2 = 4
f(4) = 4^2 = 16
So, we have:
Rate = (16 - 4)/(4 - 2)
Rate = 6

Suppose a deposit of $ 2 , 000 in a savings account that paid an annual interest rate r (compounded yearly) is worth $ 2 , 209 after 2 years. using the formula a = p ( 1 + r ) t , we have 2 , 209 = 2 , 000 ( 1 + r ) 2 solve for r to find the annual interest rate (to the nearest tenth).
Answer:
5.1% (nearest tenth)
Step-by-step explanation:
Annual Compound Interest Formula
[tex]\large \text{$ \sf A=P\left(1+r\right)^{t} $}[/tex]
where:
A = final amountP = principal amountr = interest rate (in decimal form)t = time (in years)Given:

[tex]\implies \sf 2209=2000\left(1+r\right)^{2}[/tex]
[tex]\implies \sf \dfrac{2209}{2000}=(1+r)^2[/tex]
[tex]\implies \sf 1.1045=(1+r)^2[/tex]
[tex]\implies \sf \sqrt{1.1045}=1+r[/tex]
[tex]\implies \sf r = \sqrt{1.1045}-1[/tex]
[tex]\implies \sf r = 0.05095194942...[/tex]

Explain what the result of your proof tells you about angles a and b. Specifically, if you measured one angle, what would you know about the other? (2 points)
If the measure of one of the angles ∠a or ∠b is known, then the other angle is given by subtracting the known angle from 180°
What are supplementary angles?Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line.
The required two-column proof is presented as follows;
Statement Reason
∠1 and ∠a are linear pair angles Given
∠1 + ∠a = 180° Linear pair ∠s are supplementary
∠2 and ∠b are linear pair angles Given
∠2 + ∠b = 180° Linear pair ∠s are supplementary
∠a and ∠b are consecutive interior ∠s Definition
x║y Given
∠1 and ∠b are corresponding angles Definition
∠1 ≅ ∠b Corr. ∠s formed between║ lines
∠1 = ∠b Definition of congruency
∠a + ∠b = 180° Substitution property
∠a and ∠b are supplementary Definition
We can conclude from the proof that given ∠1 and ∠b are located in corresponding locations relative to the common transversal of the parallel lines, they (∠1 and ∠b) are equal.
Therefore, the sum of ∠a and ∠b is 180°, given that the sum of ∠1 and ∠a is 180° by substitution property of equality. So, ∠a and ∠b are supplementary angles.
Therefore, If the measure of one of the angles ∠a or ∠b is known, then the other angle is given by subtracting the known angle from 180°

What is the absolute value of -6 ?
Answer:
the answer is just 6
Step-by-step explanation:
Answer:
Step-by-step explanation:
An absolute value of a number is written like this | x |, where x could be any number that you want.
The absolute value is a math function that counts from your given number to 0.
Example: If you put the number 3, the function will count from 3 to 0, and the number will be 3.
| 3 | = 3
If you input the number 8, from 8 to 0 are 8 numbers. So, the output's function will be 8.
| 8 | = 8
If you input a negative number, for example, -6, the function will do the same thing. It will count from -6 to 0. From -6 to 0, are 6 numbers.
| -6 | = 6
Any number that you input in this function, will always output the same number, but positive
| -10 | = 10
| -46348 | = 46348

How does this equation model the situation?The best equation would be the one that gives the closest value of y to the value of the actual value of y on the table.
The first two equations can be ruled out because the table shows that this is not a linear model as there is no constant rate of change.
Test the other two equations:

How do you find what exponents of i are? like I know i^2 is -1, but how are you supposed to figure out i^26? do you have to write it all out?
THANK YOU
Answer:
-1
Step-by-step explanation:
so "i" is the square root of -1 (√-1). We know that i² = (√-1)², and that when we square a square root we end back up with whatever is inside of the square root.
This is why i² = -1
We can find a pattern from writing out a few exponents:
i¹ = i
i² = -1
i³ = -i [(-1)(i)]
i⁴ = 1 [-1 · -1]
------
i⁵ = i [(1)(i)]
i⁶ = -1 [(i)(i)]
i⁷ = -i [(-1)(i)]
i⁸ = 1 [(-i)(i)= -(i²)= -(-1) = 1]
------
i⁹ = i [1 · i]
we can see that the pattern of i repeats every 4 numbers, so by dividing 26 by 4 (and finding the remainder), we can figure out which step of the pattern we are on
26 / 4 = 6 [remainder of 2]
we know that there is a remainder of 2, meaning that we are on the "second step" in the pattern: -1
you can do the same thing for any number
hope this helps!!
Answer:
-1
Step-by-step explanation:
4 goes into 26 6 times, and then there's 2 remainder, so it's the same thing as i², which is -1
hope this is helpful :)
Eleanor randomly chooses a number from 1 to 10. what is the probability she chooses a number greater than 5?
The probability she chooses a number greater than 5 will be 1/2 or 0.5.
What is probability?Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.
Probability = (Favorable event) / (Total event)
Eleanor randomly decides a number from 1 to 10.
Then the probability she chooses a number greater than 5 will be
Total event = 10
Favorable event = 5 {6, 7, 8, 9, 10}

Which equation is the inverse of y = 9x² - 4?
Answer:
y = ± [ √(x+4) ] / 3
Step-by-step explanation:
1) To find the inverse of the function y = 9x2 – 4, exchange the variables x and y, and then solve for the new y.
2) Exchange of the variables: y = 9x^2 – 4 → x = 9y^2 – 4
3) Solve for y:
=> 9y^2 = x + 4
=> y^2=> y = ± [ √(x + 4) ] / 9
= > y = ± [ √(x + 4) ] / 3
