One positive number is 2 less than another. The sum of their squares is 34. What is the smaller number?
Answers
The smaller number is 3. The number 3 squared is 9, plus the other number 5 squared, which is 25. when you add them, you get 34
Step-by-step explanation:
x = first number
y = second number
a. x+2 = y
b. x^2 + y^2 = 34
Replace y from equation a into equation b:
x^2 + (x+2)^2 = 34
Expand it
x^2 + x^2 + 4x + 4 = 34
2*x^2 + 4x = 30
2x^2 + 4x - 30=0
solving x:
x = -5 and x =3 , it says it is a positive number, then it is x is 3
and the second number, y = x + 2
y = 5
Lets test it!
3^2 + 5^ 2 = 9 + 25 = 34

Answer:
The percentage change each year is 2%
Step-by-step explanation:
Generally, we can have an exponential equation written as;
f(t) = I( 1 + r)^t
where f(t) is the value at a certain time
I is the initial value at t = 0
r is the growth rate
t is the time we are looking at
Thus, we have it that;
1.02 = 1 + r
r = 1.02 -1
r = 0.02
So, let us write 0.02 as a percentage
We have this as 2/100 which is the same as 2%
The percentage change each year is 2%

Find the perimeter of the object
Help step by step please!
Answers
Answer:
29.42 units
Step-by-step explanation:
1) Find the perimeter around the semi-circle
To do this, we find the circumference of the circle using the given diameter:
[tex]C=\pi d[/tex] where d is the diameter
Plug in 6 as the diameter
[tex]C=\pi (6)\\C=6\pi[/tex]
Divide the circumference by 2
[tex]\frac{6\pi }{2} \\= 3\pi[/tex]
Therefore, the perimeter around the semi-circle is 3π units.
2) Find the perimeter around the rest of the shape
Although it's impossible to determine the lengths of the varied sides on the right side of the shape, we know that all of those vertical sides facing the right add up to 6. We also know that all of those horizontal sides facing up add up to 7. Please refer to the attached images.
Therefore, we add the following:
7+6+7
= 20
Therefore, the perimeter around that area of the shape is 20 units.
3) Add the perimeter around the semi-circle and the perimeter around the rest of the shape
[tex]20+3\pi \\= 20+9.42\\= 29.42[/tex]
Therefore, the perimeter of the shape is approximately 29.42 units.
I hope this helps!

$725
$1,050
$1,375
75
H. p = 13c + 75
100
J. c = 13p + 75
Answers
Answer:
The answer is j
Step-by-step explanation:
The equations shows the relationship between c and p is p= 13c + 75.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have table which shows amount that a catering company charges based on the number of people at an event.
So, the equation that can framed from the table as
(y- 400)= (725- 400) / (50-25) . (x-25)
y- 400 = (325/ 25) (x-25)
y-400 = 13(x-25)
y-400 = 13x - 325
y = 13x - 325 + 400
y= 13x + 75
or p = 13c+ 75
