Step-by-step explanation:
As we can see, there are perfect squares in the first two expressions
thus, we have it that;
√(25x) = 5√x
√(4x) = 2√x
so we have the expression as;
5 √x - 2 √(x + 2 √x
= 5√x
What is the intermediate step in the form (x + a)2 = b as a result of completing the
square for the following equation?
x2 – 14 = 2x – 14
Answer:
y=(x-1)^2 -1
Step-by-step explanation:
If you put it in the form (x-a)^2=b
The answer will be (x-1)^2=1
Why is 6/5 not equivalent to 3/2
Answer:
It is the first choiceStep-by-step explanation:
[tex] \frac{3 \times 2}{2 \times 2} = \frac{6}{4} \\ \\ \frac{6}{4} \: \: is \: not \: equal \: to \: \: \: \: \frac{6}{5} [/tex]
The ratio 3 / 2 is multiplied by 2 on both the denominator and numerator to get the value 6 / 4, but the denominator part is not equal to 5, hence 6/5 is not equivalent to 3/2, so option A is correct.
What is the ratio?It is the comparison of one quantity with another. For example, if your weight is 30 kg and your father's weight is 90 kg, then the ratio of weight is 1:3.
Given:
6 / 5 and 3 / 2
As you can see the numerator of 3 / 2 is multiplied by 2 to get the value 6, so the denomination should also be multiplied by the number 2,
(3 × 2 ) / (2 × 2)
6 / 4
But the result came as 4 on the numerator,
Thus, 6 / 5 and 3 / 2 are not equivalent.

A tailor needs to make uniforms for 32 students from a piece of cloth. If the length of that piece 45 3/4m and each student requires 1 1/8m, calculate the length of cloth that would be left
Answer:
uniform for 1 student = 1 1/8 = 9/8
uniform 32 students = 32 x 9/8 = 36m
Total cloth = 45 3/4 = 183/4 = 45.75m

Find the volume of the cone. Round your answer to the nearest tenth if necessary. Use 3.14 for n.
12 cm
6 cm
The volume of the cone is about
cm?
Answer:
113.112cm^3
Step-by-step explanation:
Given data
Height= 12cm
Diamter= 6cm
Radius= 3cm
The expression for the volume of a cone is given as
V= 1/3*πr^2h
Substitute
V= 1/3*3.142*3^2*12
V= 1/3*3.142*9*12
V= 1/3*339.336
V=113.112cm^3
Hence the volume is 113.112cm^3
A shelf is built on a wall, as shown below. What is the value of x?
Answer:
X=25
Step-by-step explanation:
All angles of a triangle add up for 180
We know that there is a 90 degree right angle.
So (x+25)+(2x-10)=180-90
Remove parenthesis since they don't matter in this problem.
x+25+2x-10=90
Combine similar terms
3x+15=90
Subtract 15 from both sides
3x=75
Divide both sides by 3
x=25

The first two logarithmic expressions are true and the third one is false.
What is a logarithm?The logarithm is exponentiation's opposite function in mathematics.
This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b. For instance, because 100 = 10², the logarithm of 100 in base 10 is 2, or log10 = 2.

G(x)=3/x find g'(x) a) by using the quotient rule: b) by first rewriting the expression using exponents and then differentiating.
Answer:
a) The quotient rule is:
if: f(x) = 1/g(x)
Then:
[tex]f'(x) = -\frac{1}{(g(x))^2}*g'(x)[/tex]
In this case, we have:
G(x) = 1/x
Then we can write this as:
G(x) = 1/h(x) with h(x) = x, and h'(x) = 1
Using the above rule we get:
G'(x) = -(1/h(x)^2)*h'(x) = -1/x^2
b) For a function like:
f(x) = x^n
we have that:
[tex]f'(x) = n*x^{n - 1}[/tex]
Here we can write G(x) = x^-1
Then we have n = -1
If we use the above rule, we get:
[tex]G'(x) = (-1)*x^{-1-1} = -1*x^{-2} = \frac{-1}{x^2}[/tex]
So we got the same result using both methods.
Find the vertices of the hyperbola. Enter the smallest coordinate first.
Answer:
([-3], [0]), ([3], [0])
Step-by-step explanation:
The given equation of the hyperbola is presented as follows;
[tex]\dfrac{x^2}{9} - \dfrac{y^2}{49} = 1[/tex]
The vertices of an hyperbola (of the form) [tex]\dfrac{x^2}{a^2} - \dfrac{y^2}{b^2} = 1[/tex] are (± a, 0)
The given hyperbola can we presented in a similar form as follows;
[tex]\dfrac{x^2}{9} - \dfrac{y^2}{49} = \dfrac{x^2}{3^2} - \dfrac{y^2}{7^2} = 1[/tex]
Therefore, by comparison, the vertices of the parabola are (± 3, 0), which gives;
The vertices of the parabola are ([-3], [0]), ([3], [0]).

Answer:
7.) x = 12
9.) x = 4
Step-by-step explanation:
7.) Angle Y and Angle X both add up to 180
=> 40 + 12x - 4 = 180
=> 36 + 12x = 180
=> 12x = 180 - 36
=> 12x = 144
=> x = 12
9.) Angle W and Angle X add up to 180
=> 145 + (-1) + 9x = 180
=> 144 + 9x = 180
=> 9x = 180 - 144
=> 9x = 36
=> x = 36 / 9
=> x = 4
