Answer : 34
Step-by-step explanation:
Solution,
Given,
base = 16
perpendicular = 30
hypotenuse = ?
Now,
By the formula of Pythagoras Theorem,
h^2 = p^2 + b^2
h^2 = 30^2+16^2
h^2 = 900+256
h = sqrt ( 1156 )
h = 34
Therefore, the value of x (hypotenuse) is 34.

Is the function an exponential function?
y=(-2)^x
Answers
Answer:Yes
Step-by-step explanation:
the normal exponential function is ab^x, where a represent the growth( sometimes you don't need this part), b is average rate of growth and x is the number of times we exponate. [tex]-2^{x}[/tex] is a exponetital function because it includes the b and x part. The a part is someetimes used but not always.
A function is a relationship between inputs where each input is related to exactly one output.
An exponential function is a function in the form
y = [tex]a^{x}[/tex]
Where a = constant and x = variable.
y = [tex](-2)^{x}[/tex] is an exponential function.
Where -2 is a constant and x is a variable.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
y = [tex](-2)^{x}[/tex]
An exponential function is a function in the form
y = [tex]a^{x}[/tex]
Where a = constant and x = variable.
Example:
y = [tex]3^{x}[/tex]
y = [tex]5^{x}[/tex]
We see that,
y = [tex](-2)^{x}[/tex]
-2 is a constant
x is a variable
Thus,
y = [tex](-2)^{x}[/tex] is an exponential function.
Where -2 is a constant and x is a variable.

A carpenter has a wooden stick that is 84 centimeters long. She cuts off 25% from the end of
the stick. Then she cuts the remaining stick into 6 equal pieces. What is the length of each
piece?
How did you get 63?
Answers
=======================================================
Explanation:
25% = 25/100 = 0.25
25% of 84 = 0.25*84 = 21
So 21 cm has been cut off, leaving 84-21 = 63 cm left over
Or you could say that if 25% has been cut off, then 75% of the stick remains
So, 75% of 84 = 0.75*84 = 63 cm remains.
The remaining length of 63 cm is cut into 6 equal pieces
Each smaller piece is 63/6 = 10.5 cm long

Step-by-step explanation:
The common difference d in an arithmetic sequence is
d = a₂ - a₁ = - 1 - (- 3) = - 1 + 3 = 2
To obtain a term in the sequence add d = 2 to the previous term, that is
a₄ = a₃ + 2 = 1 + 2 = 3
a₅ = a₄ + 2 = 3 + 2 = 5
I need to find the missing angle thank you
Answers
Answer:
The missing angles measure is 70 degrees
Step-by-step explanation:
First we must complete the left triangles last measure:
60+65+x=180
x=55
Then we have to make all of those three middle angles equal 180:
55+50+y=180
105+y=180
y=75
Now we add 75 to 35 to the missing angle to get 180:
75+35+z=180
110+z=180
z=70
The missing angles measure is 70 degrees

Answers
Answer:
x = -5 and y = 2
Step-by-step explanation:
You want to start by writing these two equations:
x + y = -3
and
x - y = -7
Then, you want to add the solutions to these two equations, like so:
-3 + -7 = -10
Then, to find the x value, because x > y, divide the answer by two:
-10/2 = -5
So, the x value is -5.
With this information, you can figure out that the y value is 2.
Check the answer:
-5 + 2 = -3
-5 - 2 = -7
