Find the domain of f(x)= x^2+4
Answer:
(Negative Infinity to Positive Infinity)
Step-by-step explanation:
A domain is all x values that can go into a function. This is a quadratic. A quadratic can accept any real number so the domain is

A bag contains 7 red marbles, 8 blue marbles, and 9 green marbles. What is the
probability of choosing a blue marble when one marble is drawn?
Answer:
The probability of choosing a blue marble is 1/3.
Step-by-step explanation:
Add up all of the marbles.
7+8+9=24.
Next, you get the fraction of the chosen marble type over all marbles. In this case, it's blue, so it's 8/24
Finally, you must simplify the fraction.
1/3 is the simplest form of 8/24.

If it costs $5.35 per day for a 5 day work week to ride the bus, and a weekly pass is $25, how much could a person save by buying the pass?
Answer:
$1.75
Step-by-step explanation:
basically we are comparing
5 daily passes vs. a weekly pass.
5 daily passes = 5×$5.35 = $26.75
a weekly pass = $25.00
so, the difference is 26.75 - 25 = $1.75
Find the minimum value of the function:

Divide by rationalizing the denominator.
3+5i/10+3i
A. 25+47i/109
B. 60-18i/109
C. 100-30i/109
D. 45+41i/109
Answer:
D
Step-by-step explanation:
Multiply the numerator and denominator by the conjugate of the denominator.
Note that i² = - 1
The conjugate of 10 + 3i is 10 - 3i , then
[tex]\frac{(3+5i)(10-3i)}{(10+3i)(10-3i)}[/tex] ← Expand numerator/denominator using FOIL
= [tex]\frac{30-9i+50i-15i^2}{100-30i+30i-9i^2}[/tex] ← simplify
= [tex]\frac{30+41i+15}{100+9}[/tex]
= [tex]\frac{45+41i}{109}[/tex] → D

Find the area of the circle.
Use 3.14 for it.
d = 8 cm
A = [?] cm2
A= 7Tr2
Answer:
50.24 cm^2.
Step-by-step explanation:
If d = 8 then r = 4 cm.
Area = 3.14 * r^2
= 3.14 * 4^2
= 50.24 cm^2.

The expression 146 - 144 is equal to
O 142
1
14 10
Step-by-step explanation:
I am sure you mistyped something here and/or there is something missing.
because 146 - 144 = 2
and nothing in the answer options shows anything like it.
now, if the problem actually said for example
14×6 - 14×4
that could be expressed as
14×(6-4) = 14×2
and that could be the first answer option (also with missing multiplication symbol).

Find the least common multiple of 9 and 15
Answer:
45
Step-by-step explanation:
9:9,18,27,36,45
15:15,30,45
Answer:
45
Step-by-step explanation:
The least common multiple is the smallest number found between the two numbers, in this case 9 and 15, while skip counting from each number. Or the like the multiplication table.
Multiples for 9:
9, 18, 27, 36, 45, 54, 63...
Multiples for 15:
15, 30, 45, 60, 85...
45 is the first and common number that appears in both multiples of 9 and multiples of 15. Therefore, it will be the least common multiple of 9 and 15.

A sum of Rs 105 is divided into two parts.if two times the greater part is 15 less than three times the smaller part, find the parts of the sum.
Answer:
Step-by-step explanation:
Let the greater part = x
Smaller part = 105 - x
2*(greater part) = (3*smaller part) - 15
2*x = 3*(105 -x) - 15
Use distributive property
2x = 3*105 - 3*x - 15
2x = 315 - 3x - 15
2x = 300 - 3x
Add 3x to both sides
2x +3x = 300
5x = 300
Divide both sides by 5
x = 300/5
x =60
Smaller part = 105 - 60 = 45
Greater part = Rs. 60
Smaller part = Rs. 45

which of the following is a counterexample of this statement?
If an angle is acute, then it measures 80°.
A. a 100° angle
B. a 90° angle
C. a 80° angle
D. a 70° angle
Answer:
a 70° angle
Step-by-step explanation:
an acute angle measure between 0° and 90° so a counterexample for the statement is the 70° angle which is also an acute angle that doesn't measure 80°

find three consecutive even integers for which -4 times the sum of the first and third is 192
Answer:
-26-24-22Step-by-step explanation:
Let x be the smallest number (first)
Let (x + 2) be the second number (second)
Let (x + 4) be the greatest number (third)
Set equation according to the given information
-4 [x + (x + 4)] = 192
Simplify parentheses
-4 [x + x + 4] = 192
-4 [2x + 4] = 192
Expand bracket and apply the distributive property
(-4) · 2x + (-4) · 4 = 192
-8x - 16 = 192
Add 16 on both sides
-8x - 16 + 16 = 192 + 16
-8x = 208
Divide -8 on both sides
-8x / -8 = 208 / (-8)
[tex]\boxed{x=-26}[/tex]
Find the value of the second term
x + 2 = (-26) + 2 = [tex]\boxed{-24}[/tex]
Find the value of the third term
x + 4 = (-26) + 4 = [tex]\boxed{-22}[/tex]

The length of a rectangle is three times its width. It the perimeter of the rectangle is 96m, find the length and breadth of the rectangle
Let the width, w = x m
So, according to the Question,
The length, l = 3x m
Perimeter of a rectangle = 2 (l + w) m
Perimeter of the rectangle = 96 m
It's equation will be,
2 (3x + x) m = 96 m
or, 4x m = 96/2 m
or, 4x m = 48 m
or, x m = 48/4 m
or, x m = 12 m
Therefore, the width and the length of the rectangle is 12 m and 3(12) m = 36 m respectively.
