Answer:
4[tex]\sqrt{2}[/tex]
Step-by-step explanation:
factor the square root of 32
to get a total of 32, you do 4 times 4, which is 16
16 times 2 =32
16 is a perfect square so it's outside of the square root symbol, but you can't find the square root of 2 without it being irrational.
So,
final answer: 4[tex]\sqrt{2}[/tex]
Work out the mean of these three numbers
Answer:
110
Step-by-step explanation:
Let the three numbers be 100, 110 and 120
100 + 110 + 120 = 330
Total numbers = 3
[tex]mean = \frac{330}{3} = 110 \\ [/tex]
What is the correct inverse function for f(x)=In(3x)?
Answer:
f⁻¹(x) = eˣ / 3
Step-by-step explanation:
f(x) = In(3x)
y = In(3x)
swap x and y: x = In(3y)
solve y: eˣ = 3y
y = eˣ / 3
f⁻¹(x) = eˣ / 3
Last year, Rebecca's car insurance cost her £2043. This year it only cost her £1675.26 By what percentage has Rebecca's car insurance been reduced?
Answer:
Step-by-step explanation:
Rebecca's car insurance been reduced by 18%
What is percentage?A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction.
Given that, Last year, Rebecca's car insurance cost her £2043. This year it only cost her £1675.26.
Percentage decrease = (Final value - initial value) / initial value × 100
Final value = £1675.26
Initial value = £2043
Percentage decrease = (2043 - 1675.26) / 2043 × 100
= 367.74 / 2043 × 100
= 0.18 × 100
= 18 %
Hence, Rebecca's car insurance been reduced by 18%

what is the least common denominator of 9/10 and 1/4
Answer:
Step-by-step explanation:
Solution:
Rewriting input as fractions if necessary:
9/10, 1/4
For the denominators (10, 4) the least common multiple (LCM) is 20.
LCM(10, 4)
Therefore, the least common denominator (LCD) is 20.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
9/10 = 9/10 × 2/2 = 18/20
1/4 = 1/4 × 5/5 = 5/20

Simplify the expression using the order of operations. The nature park has a pride of 4 lions and 8 cubs. The adults eat 7 pounds of meat each day and the cubs eat 4 pounds. Simplify 4 × 7 + 8 × 4 to find the amount of meat consumed each day by the lions. The lions consume pounds of meat each day.
Answer:
60 pounds of meat
Step-by-step explanation:
Number of lions = 4
Pounds of meat consumed = 7 pounds each
Number of cubs = 8
Pounds e meat consumed = 4 pounds each
Amount of meat consumed each day by the lions = 4 × 7 + 8 × 4
Multiply first
= 28 + 32
= 60 pounds of meat
The lions consume 60 pounds of meat each day.

Which equation best represents the graph?
Answer:
The third one
Step-by-step explanation:
The graphs in the reversed shape of a cup are the graphs of quadratic equations whose coefficient of
x^2 is negative.
So, the answer must be either the first or the third.
It can be seen that when x= -4, y becomes 5.
Substituting the value of x, the third equation gives the value 5.
So, the answer is the third one.

The outside diameter (od) of a pipe is 4 9/32 inches. The walls are 7/32 inches thick. find the inside diameter.
Please explain how you got your answer.
The inside diameter would be the outside diameter minus 2 of the wall thicknesses.
4 9/32 - (2 x 7/32)
Simplify:
4 9/32 - 14/32
Because 14/32 is larger than 9/32 change one of the hole numbers to a fraction: 1 = 32/32
rewrite 4 9/32 as 3 41/32
Now subtract:
3 41/32 - 14/32 = 3 27/32 inside diameter.

Use Substitution to solve the following System of Equations.
y=-22 - 4
y = 4x + 2
Oh
Answer:
X=4
Y=18
I think
Answer:
(- 1, - 2 )
Step-by-step explanation:
Given the 2 equations
y = - 2x - 4 → (1)
y = 4x + 2 → (2)
Substitute y = 4x + 2 into (1)
4x + 2 = - 2x - 4 ( add 2x to both sides )
6x + 2 = - 4 ( subtract 2 from both sides )
6x = - 6 ( divide both sides by 6 )
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (2)
y = 4(- 1) + 2 = - 4 + 2 = - 2
solution is (- 1, - 2 )

What is the inverse operation do use to solve for t?
t - 19=2
We use addition, or rather the addition property of equality.
t-19+19=2+19
t=21
:D
Step-by-step explanation:
Addition is the inverse operation.
inverses:
addition/subtraction
multiplication/ division
If you need to solve for t:
t-19=2
add 19 to both sides to isolate the variable (t)
t=21

Which quadratic function has a vertex point of (3,5) and passes through the
point (-2,55)?
9514 1404 393
Answer:
f(x) = 2(x -3)² +5
Step-by-step explanation:
For vertex (h, k) and scale factor 'a', the vertex form is ...
f(x) = a(x -h)² +k
We can fill in the values of h and k from your vertex, and use the values of the extra point to find 'a'.
55 = a(-2 -3)² +5
50 = 25a . . . . . . . . subtract 5
a = 2 . . . . . . . . . . . divide by 25
So, the function is ...
f(x) = 2(x -3)² +5
__
In standard form, that will be ...
f(x) = 2x² -12x +23
