Answer: x = -1
Step-by-step explanation:
The radius needs to be positive, so 2x + 3 > 0. Solving for x, we get x > -3/2. The smallest integer larger than -3/2 is -1, so x = –1.

An equiangular octagon has four sides of length $1$ and four sides of length $\frac{\sqrt{2}}{2}$, arranged so that no two consecutive sides have the same length. What is the area of the octagon
If the corner cut has length 1, then each corner triangle has legs of length [tex]\dfrac1{\sqrt2}[/tex], and hence area [tex]\dfrac12\cdot\dfrac1{\sqrt2}\cdot\dfrac1{\sqrt2}=\dfrac14[/tex]. The original square then has side lengths [tex]\dfrac1{\sqrt2}+\dfrac1{\sqrt2}+\dfrac1{\sqrt2}=\dfrac3{\sqrt2}[/tex], so its total area is [tex]\left(\dfrac3{\sqrt2}\right)^2=\dfrac92[/tex]. Then subtract the triangles' areas from the square's area to get the octagon's area, [tex]\dfrac92-4\cdot\dfrac14=\dfrac92-1=\boxed{\dfrac72}[/tex].

Charlie has twice as many hair clips as Abi and Jaxon has half as many hair clips as Abi. If Jaxon 2 1/2 dozen hair clips, how many hair clips do the girls have altogether?
Answer:
Total is hair clips is 210
Step-by-step explanation:
Jason has 2 1/2 dozen = 30
Jason has half of abi
So abi has 60 clips
And
Charlie has twice than abi
So multiple abi clips with 2
60 × 2 =120
To all clips add them up
120 + 60 + 30 = 210
Answer:
210 clips
Step-by-step explanation:
2 1/2 dozen=30 clips
Abi=30x2=60 clips
Charlie=60x2=120 clips
total=120+60+30=210 clips

When downloading a large file from the internet Alice interrupted the download by closing her computer. Later that evening she resumed the download and noticed that the file was downloading at a constant rate of change. 3 minutes since resuming the download 6720 total MegaBytes (MB) of the file had been downloaded and 5 mintues since resuming the download 10560 total MegaBytes (MB) of the file had been downloaded.
Using the slope concept, it is found that the rate of download of the file is of 1920 MB/s.
What is the slope?The slope of a linear function is given by the change in the output divided by the change in the input.
In this problem:
3 minutes since resuming the download 6720 total MegaBytes (MB).5 minutes since resuming the download 10560 total MegaBytes (MB) of the file had been downloaded..Hence, in 2 minutes, there was a change of 10560 - 6720 = 3840 MB, which means that the slope is:[tex]m = \frac{3840}{2} = 1920[/tex]
The rate of download of the file is of 1920 MB/s.

Let f(x) = x^2 − 5. Find f(-3)
Answer:
f(-3)=4
Step-by-step explanation:
Substitute x=-3 into the function
f(-3)=(-3)^2-5
f(-3)=9-5
f(-3)=4
Answer:
f(-3) = 4
Step-by-step explanation:
f(x) = x² - 5
f(x) is a function with input x, meaning it is an expression which has terms involving x;
x is a variable and can be considered a space holder;
f(-3) is the function with input -3, this simply means replacing the space holder, i.e. x, with -3;
f(-3) = (-3)² - 5
f(-3) = 9 - 5
f(-3) = 4

The p-value for a one-sided t-test is 0. 10. If the test had been two-sided, what would the p-value have been?.
Considering the one-sided p-value, the p-value for a two-sided test would be of 0.20.
How to find the p-value of a test?It depends on the test statistic z, as follows:
For a left-tailed test, it is the area under the normal curve to the left of z, which is the p-value of z.For a right-tailed test, it is the area under the normal curve to the right of z, which is 1 subtracted by the p-value of z.For a two-tailed test, it is the area under the normal curve to the left of -z combined with the area to the right of z, hence it is 2 multiplied by 1 subtracted by the p-value of z, which means that the p-value for a two-tailed test is twice the p-value of a one-tailed test.In this problem, for the one-tailed test, the p-value is of 0.1, hence the p-value for a two-sided test would be of 0.20.

Given f(x)=-5x+1f(x)=−5x+1, solve for xx when f(x)=6f(x)=6.
Answer:
Answer:
The coefficient of x is 6
Step-by-step explanation:
The two expressions are
(x)=-5x+1f(x)=−5x+1
and .
f(x)=6f(x)=6.
The sum of the two expressions is
f(x)=-5x+1f(x)=−5x+1(f(x)=6f(x)=6.)
When we group like terms the expression will be,
f(x)=-5x+1f(x)=−5x+1(f(x)=6f(x)=6.)=f(x)=-5x+1f(x)=−5x+1(f(x)=6f(x)=6.)
When we simplify the expression will now be
f−5x+1(f(x)=6.)
The coefficient of x is the constant behind x in the expression.
The coefficient of x is 3 therefore the answer is 3 .
Step-by-step explanation:
By definition of the substitution method, the value of x for the function f (x) = - 5x + 1 would be x = - 1.
Given that;
The function is,
f (x) = - 5x + 1
And, f (x) = 6
Now substitute the value of function f (x) = 6;
f (x) = - 5x + 1
6 = - 5x + 1
5x = 1 - 6
5x = - 5
x = - 5/5
x = -1
Therefore, the value of x is - 1.

Step-by-step explanation:
Answer:
∠ABC = 56°
Step-by-step explanation:
The equilateral triangle is irrelevant and can be ignored.
The angle marked 62° is one of the base angles of the isosceles triangle. The other base angle (at D) will have the same measure. The sum of angles in a triangle is 180°, so you have ...
∠A +∠D +∠B = 180°
62° +62° +∠B = 180°
∠B = 180° -124° = 56°
The measure of ∠ABC is 56°.
