Answer:
x ≈ - 1.28
Step-by-step explanation:
Using the rule of logarithms
[tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]
Given
ln(x + 4) = 1 , then
x + 4 = [tex]e^{1}[/tex] ( subtract 4 from both sides )
x = [tex]e^{1}[/tex] - 4 = - 1.28 ( to the nearest hundredth )

Answer:
Quadratic Equations! Yes!
Step-by-step explanation:
Now, there are three methods to solving this:
1.Quadratic Formula
2.Factoring
3. Completing the square
Now, Based on the answers, I think it would be better if we used Quadratic Formula, as you cannot get the answer easily with factoring, and I'm a bit rusty on completing the square.
So, Quadratic Formula! To solve it using this method, we have to find x using this: [tex]x=\frac{-b+-\sqrt{b^{2} -4ac} }{2a}[/tex](the +- before the square root means it could be both positive or negative)
Where a, b are coefficients and c is a term(in a quadratic equation form: [tex]ax^{2} +bx+c=0[/tex])
So, we just have to input the stuff from our equation into the formula!
[tex]x=\frac{-4+-\sqrt{32} }{2}[/tex]
Now, we can simplify the square root of 32 into 4 times the square root of 2
[tex]x=\frac{-4+-4\sqrt{2} }{2}[/tex]
And, we can divide 2 from it all!
[tex]x=-2+-2\sqrt{2}[/tex]
So, there you have it! The Answer is C, or 3.
Hope this helps!

What is the slope of the line that is represented by the values in the table above?
Answer:
1.5
Step-by-step explanation:
Given the pair of points on the table.
Now the formula for slope, [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
To calculate the slope we only require two pair of points.
Let us take: [tex](x_1, y_1)=(-5,0)$ and (x_2, y_2)=(-3,3)[/tex]
[tex]m=\dfrac{3-0}{-3-(-5)}\\=\dfrac{3}{-3+5}\\=\dfrac{3}{2}\\m=1.5[/tex]
The slope of the linear function represented by the values in the table is 1.5.
Note: You can use any two set of values. The result will be the same.

What is the arc measure of minor arc AB in degrees?
Answer:
The measure of a minor arc is the measure of its central angle. The expression m AB is read as “the measure of arc AB.” The measure of the entire circle is 360°. The measure of a major arc is the difference of 360° and the measure of the related minor arc.

Answer: £35.60
Step-by-step explanation:
3 builders = 5 1/2 hours
1 builder = 5 1/2 * 3 = 33/2 hours
5 builders = 33/2 / 5 = 33/10 hours = 3.3
Since they are paid hourly or part of an hour at £8.90.
One builder = £8.90 x 4 = £35.60

Answer:
The volume of a sphere:
[tex]V \approx 3053.628[/tex] [tex]cm ^3[/tex]
or
[tex]V \approx 3053.63[/tex] [tex]cm^3[/tex] (Rounded to the nearest hundredth if needed)
Step-by-step explanation:
-To find the volume of sphere, you need this formula to help you solve the problem:
[tex]V = \frac{4}{3} \pi r^3[/tex]
-Use the given radius [tex]9[/tex] for the formula:
[tex]V = \frac{4}{3} \pi 9^3[/tex]
-Then, you solve:
[tex]V = \frac{4}{3}\pi \times 9^3[/tex]
[tex]V = \frac{4}{3} \pi \times 729[/tex]
[tex]V = \frac{4 \times 729}{3} \pi[/tex]
[tex]V = \frac{2916}{3} \pi[/tex]
[tex]V = 972\pi \approx 3053.628[/tex] [tex]cm^3[/tex]
-Round up to the nearest hundredth if needed:
[tex]V = 3053.63[/tex] [tex]cm^3[/tex]

What two numbers... add to 6 and multiply to -27?
Answer:
Hello There. Here is Explanation How to get the answer.
Explanation: x + y = -6 �> x = -6-y
xy = 8
(-6-y)y = 8
-6y - y^2 = 8
y^2+6y+8 = 0
(y+2)(y+4) = 0

Answer:
x = -24/7
Step-by-step explanation:
To solve, you need to multiply both sides by 10 ( the GCF of 5 and 2) to get rid of the fractions. Once multiplied, you get this:
2(4x-2) + 5(1) = 5(3x+7) - 10(1)
Now, just distribute the parenthesis:
8x - 4 + 5 = 15x + 35 - 10
Now, combine like terms:
8x + 1 = 15x + 25
15x + 25 = 8x + 1 (rearranged the equation)
Subtract the x's:
7x + 25 = 1
Now solve:
7x = -24
x = -24/7

Which is a possible turning point for the continuous
function f(x)?
O (-2,0)
O (0, -2)
O (2-1)
O (4,0)
Answer:
(0, -2)
Step-by-step explanation:
A turning point is a point at which the derivative changes sign from positive to negative or vice versa. Then, a turning point coincides with a relative maximum or a relative minimum (also known as local minimum and maximum).
From the table, we see that f(x) decreases from x = -6 to x = 0 and it increases from x = 0 to x = 6. Therefore, there is a minimum at (0, -2)

a cylinder has a diameter of 6 feet. the volume of the cylinder is 36/5π cubic feet.
enter the height, in feet, of the cylinder in decimal from. round your answer to the nearest tenth.
Answer:
Height of cylinder is [tex]\frac{4}{5}\ ft[/tex].
Step-by-step explanation:
Diameter of cylinder, D = 6 feet
Relation between Radius, R and diameter, D is given by:
[tex]R = \dfrac{D}{2}[/tex]
So, radius, R = [tex]\frac{6}{2} \Rightarrow 3[/tex] feet
Let height of cylinder be [tex]h[/tex] feet.
Formula for volume of cylinder is given by:
[tex]V = \pi R^{2} H[/tex]
Where, R is the radius of base of cylinder
and H is the height of cylinder
We are given that,
[tex]V = \dfrac{36 \pi}{5} ft^{3}[/tex]
Using formula for volume, [tex]V = \pi R^{2} H[/tex]
[tex]\dfrac{36\pi}{5} = \pi \times 3^{2} \times h\\\Rightarrow \dfrac{36\pi}{5} = \pi \times 9 \times h\\\Rightarrow h = \dfrac{4}{5} ft[/tex]
Hence, Height of cylinder is [tex]\frac{4}{5}\ ft[/tex].
