What is the area of triangle FGH? Round your answer to the nearest tenth of a square centimeter.
Answer: [tex]\text{Area}=9.8\ \text{square centimeter}[/tex]
Step-by-step explanation:
Given: The height of the triangle h= 3.0 cm
The base corresponding to the given height b= 6.5 cm
We know that the area of a triangle is given by :-
[tex]\text{Area}=\frac{1}{2}bh\\\\\Rightarrow\text{Area}=\frac{1}{2}(3)(6.5)\\\\\Rightarrow\text{Area}=\frac{19.5}{2}\\\\\Rightarrow\text{Area}=9.75\approx9.8\ \text{square centimeter}[/tex]

What is the range of this function?
Answer:
c) -16 ≤ x < 5
Step-by-step explanation:
The given function is f(x) = -3x + 2 and domain is -1 < x ≤ 6
The maximum value of the domain is 6 and the minimum value of the domain is -1.
To find the range, plugin the maximum and minimum value of the domain.
Plug in x = 6 in the given function, we get
f(6) = -3(6) + 2 = -18 +2 = -16
f(-1) = -3(-1) + 2 = 3 + 2 = 5
So the range is -16 ≤ x < 5

Two women start at the same point. they walk in opposite directions for 3 meters, then turn right and walk another 4 meters. how far apart are they?
The total distance between the two women would simply be the sum of the hypotenuse formed by the triangular path they created.
For each women:
c^2 = a^2 + b^2
c^2 = 3^2 + 4^2
c^2 = 9 + 16
c^2 = 25
c = 5 m
Therefore the distance between the two is:
distance between the two women = 2 * c
distance between the two women = 10 m

As given the epression in the question is given by
[tex]= 5\sqrt{8} - \sqrt{18} - 2 \sqrt{2}[/tex]
Now simplify the above
Terms are written as
[tex]\sqrt{8} = \sqrt{2\times 2\times 2} = 2 \sqrt{2}[/tex]
[tex]\sqrt{18} = \sqrt{3\times 3\times 2} = 3 \sqrt{2}[/tex]
Put in the above expression.
[tex]= 5\times 2 \sqrt{2} -3 \sqrt{2} - 2 \sqrt{2}[/tex]
[tex]= 10 \sqrt{2} -5 \sqrt{2}[/tex]
[tex]=5 \sqrt{2}[/tex]
[tex]Therefore\ the\ expression\ 5\sqrt{8} - \sqrt{18} - 2 \sqrt{2}\ is\ equivalent\ to\ 5 \sqrt{2} .[/tex]

What is the following product
Answer:
Option B.[tex]\sqrt[6]{200}[/tex]
Step-by-step explanation:
The given expression is ∛5.√2 and we have to find the product.
In this question ∛5 can be written as [tex]5^{\frac{1}{3} }[/tex] and [tex]\sqrt{2}=2^{\frac{1}{2}}[/tex]
We know to multiply these terms we should have the same powers of both the terms.
Now we will convert these terms to the terms having same powers.
first term [tex]5^{\frac{1}{3}}=5^{(\frac{1}{3}).(\frac{2}{2})}[/tex]
=[tex]5^{\frac{2}{6}}[/tex]
=[tex]25^{\frac{1}{6}}[/tex]
Second term √2 = [tex]2^{\frac{1}{2}}[/tex]
= [tex]2^{(\frac{1}{2}).(\frac{3}{3})}[/tex]
= [tex]2^{\frac{3}{6}}[/tex]
= [tex]8^{\frac{1}{6}}[/tex]
Now we multiply these terms
[tex]25^{\frac{1}{6}}.8^{\frac{1}{6}}[/tex]
= [tex]200^{\frac{1}{6} }[/tex]
Therefore option B is the answer.
How do you solve 3x+4y=12 and 2x=y-6
3x +4y =12
2x = y-6 Rewrite this as y = 2x+6
now replace that for y in the first equation
3x + 4(2x+6) = 12
now do all the calculations:
3x + 8x +24 =12
11x + 24 = 12
11x = -12
x = -12/11 = -1 1/11
now substitute -12/11 for x in the 2nd equation and solve
y = 2x+6
y = 2(-1 1/11) +6
y = 42/11 = 3 9/11
The difference between a number and 12 is 20
Describe the transformation f(x) = √x + 1 − 5 in words. The parent function f(x) = √x has been shifted 1 unit and 5 units.
Answer:
We are given,
The transformed function is [tex]f(x)=\sqrt{x+1}-5[/tex].
So, we can see that,
The parent function is [tex]f(x)=\sqrt{x}[/tex].
Then, we have,
The parent function is translated 1 units to the left to give [tex]\sqrt{x+1}[/tex].
Then, it is translated 5 units downwards to give the function [tex]\sqrt{x+1}-5[/tex].
Hence, we have,
The parent function [tex]f(x)=\sqrt{x}[/tex] is translated 1 unit to the left and 5 units down.The parent function f(x) = √x has been shifted 1 unit left and 5 units down
The parent function of a square root function is represented as:
[tex]f(x) = \sqrt x[/tex]
When the function is shifted 1 unit left, we have the following equation
[tex]f(x) = \sqrt {x + 1}[/tex]
When the function is shifted 5 units down, we have the following equation
[tex]f(x) = \sqrt {x + 1} - 5[/tex]
Hence, the parent function f(x) = √x has been shifted 1 unit left and 5 units down

How many kilometers can the prius travel on 16 liters of gasoline?
Prius can travel up to 4.23 × x kilometers on 16 liters of gasoline.
It is given that Prius runs on gasoline.
We have to find out that how many kilometers it can run if amount of gasoline is 16 liters.
What will be the value of 16 times of a number x ?
The value will be ; 16 × x .
No. of kilometers Prius travels depends on what is the model of Prius . Also quality of roads makes a difference.
∵ 1 liter = 0.264172 gallons
⇒ 16 liters = 16 × 0.264172 = 4.23 gallons
Let's say a Prius travels x kilometers per gallon.
So ; on 16 liters of gasoline , Prius will travel ;
x × 4.23 = 4.23 × x kilometers
Thus , Prius can travel up to 4.23 × x kilometers on 16 liters of gasoline.

Which of the following functions illustrates a change in amplitude?
A. y = 3cos4x
B. y = 1+sinx
C. y = -2-cos(x - pi)
D. y = tan2x
Answer:
Correct option is A.
Step-by-step explanation:
Given the following functions we have to choose the option which illustrates a change in amplitude.
Multiplying a sine or cosine function by a constant changes the graph of the parent function i.e results in change in the amplitude of function. Amplitude is the measure of distance from the sinusoidal axis to the maximum or the minimum.
Option A: y = 3cos4x
The parent function is f(x) = cos x.
The amplitude of function changes from 1 to 3.
Option B: y = 1+sinx
The parent function is f(x) = sin x
The amplitude remains same i.e 1
Option C: y = -2-cos(x - pi)
Here also remains same.
Option D: y = tan 2x
The tangent function does not have an amplitude because it has no maximum or minimum value.
Hence, correct option is A.
Answer:
y= 3cos4x
