Answer:
b. T <7,-2> (RSTU); (2,-1)
Step-by-step explanation:
The given triangle has vertices R(-5, -5), S(-1,-5), T(-1,1) and U(-5,1).
Let the translation rule be T(a,b).
Then the mapping for the translation will be;
[tex](x,y)\to (x+a,y+b)[/tex]
Then the point R(-5,-5) has the image;
[tex]R(-5,-5)\to R'(-5+a,-5+b)=R'(2,-7)[/tex]
This implies that;
[tex]-5+a=2[/tex]
[tex]\Rightarrowa=2+5=7[/tex]
and
[tex]-5+b=-7[/tex]
[tex]\Rightarrow b=-7+5[/tex]
[tex]\Rightarrow b=-2[/tex]
Therefore the translation rule is T(7,-2)
Hence;
[tex]U(-5,1)\to U'(-5+7,1-2)=U'(2,-1)[/tex]

ANSWER:
2 and 1/4
Step-by-step explanation:
Write the expression: the quantity x minus 3 divided by y. A) x − 3 y Eliminate B) y x − 3 C) x − 3 y D) y x − 3
The correct expression that represents the quantity x minus 3 divided by y is: C) [tex]\( \frac{x - 3}{y} \)[/tex]
To solve the given mathematical problem, we need to translate the verbal expression into a mathematical one. The phrase the quantity x minus 3 indicates that we should subtract 3 from x, which gives us [tex]\( x - 3 \)[/tex]. Then, the word divided tells us that this quantity should be divided by y, which can be represented mathematically as [tex]\( \frac{x - 3}{y} \)[/tex].
Let's examine the options provided:
A) [tex]\( x -3y \)[/tex]
This option represents the expression x minus 3 times y, which is not the same as the quantity x minus 3 divided by y.
B) [tex]\( yx -3 \)[/tex]
This option represents the expression y times x minus 3, which is also not the same as the quantity x minus 3 divided by y.
C) [tex]\( \frac{x - 3}{y} \)[/tex]
This option correctly represents the quantity x minus 3 divided by y, which is what we are looking for.
D) [tex]\( yx - 3 \)[/tex]
This option is similar to option B and represents the expression y times x minus 3, which again is not the same as the quantity x minus 3 divided by y.
Therefore, the correct answer is option C, which correctly represents the division of the quantity x minus 3 by y.
The complete question is-
Write the expression: the quantity x minus 3 divided by y.

A point located at (3, -2) is translated right 3 units and down 4 units. What are the coordinates of the image? (0, -2) (6, -6) (6, 2) (0, -6)
Answer:
(6,-6)
Step-by-step explanation:
Because if you move to the right 3 units you add 3 to the x-axis number or in this case 3, so 3+3=6, and if you move down 4 units its the same as subtracting 4 from the y-axis number or in this case -2 so, -2-4=-6. Which gives you (6,-6).

The area of the surface of a sphere is described by the formula S=4(3.14)r^2. The earth has a radius of 3960 miles and dry land forms 29.2% of the earth’s surface. What is the area of the dry land on earth?
Answer: [tex]57,512,581.63miles^2[/tex]
Step-by-step explanation:
Substitute the value of the radius of the Earth into the formula given in the problem, where r is the radius, to obtain the surface area of the Earth:
[tex]S=4(3.14)r^2\\S=4(3.14)(3,960miles)^2\\S=196,960,896miles^2[/tex]
The problem says that the dry land forms 29.2% of the Earth’s surface, therefore, multiply the surface area by [tex]\frac{29.2}{100}=0.292[/tex]
Threfore, the area of dry land is the following:
[tex]S_{land}=(0.292)(196,960,896miles^2)=57,512,581.63miles^2[/tex]
Final answer:
To find the area of the dry land on Earth, first, calculate the Earth's total surface area with the formula S=4(3.14)r². Given a radius of 3960 miles, this results in about 197,920,640 square miles for the total surface. Multiplying this by 29.2% (or 0.292) gives approximately 57,780,666.88 square miles of dry land.
Explanation:
The question asks for the area of the dry land on Earth, given Earth's radius and the percentage of its surface that is dry land. To find this, first calculate the total surface area of the Earth using the formula S = 4(3.14)r², where r is the radius of the Earth (3960 miles). The formula accounts for the surface area of a sphere. After calculating the total surface area, we then calculate 29.2% of this area to find the dry land's surface area.
Step-by-Step Calculation:
Calculate the total surface area of the Earth: S = 4(3.14)(3960)²
Find the area of the dry land by multiplying the total surface area by 29.2% (or 0.292).
Using the steps above:
S = 4(3.14)(3960)² = 197,920,640 square miles (approx.) as the total surface area.
Area of dry land = 197,920,640 * 0.292 = 57,780,666.88 square miles (approx.).
Simplify the expression square root of 6 times the square root of 33 plus 7
Answer:
3√(22) + 7
Step-by-step explanation:
The way this is worded can be interpreted two different ways so just to cover the bases, I'll do both. I'm confident they are asking for way 1 though because it wants you to simplify the expression, not evaluate. Way 2 gives you a solution rather than an exact equation.
Number 1
√(6) x √(33) + 7
= √(6 x 33) + 7
= √(198) + 7
= √(9 x 22) + 7
= 3√(22) + 7
Number 2
√(6) x √(33 + 7)
= √(6) x √(40)
= √(6) x (4√(10))
= 4√(60)
= 8√(15)
The simplified expression for [tex]\sqrt{6} \times \sqrt{33} + 7[/tex] is [tex]3\sqrt{22} + 7[/tex]
To simplify square root of 6 times the square root of 33 plus 7 we need to first write it mathematically. We get:
[tex]\sqrt6 \times \sqrt{33}+7[/tex]
Using BODMAS, we first multiply the roots. This will give us:
[tex]\sqrt{6} \times \sqrt{33} + 7 = \sqrt{6 \times 33} +7[/tex]
Now we need to expand the digits in square by expressing them as a product of their prime factors so that common pairs can be taken out of the root. This can be done as follows:
[tex]\sqrt{6 \times 33} +7 = \sqrt{(3 \times 2)\times (3\times11)} +7[/tex]
We can see that there are two pairs of 3. Thus we extract 3 times 3 as it is a perfect square for 9 and we get:
[tex]3\sqrt{( 2\times 11)} +7 = 3\sqrt{2}+7[/tex]
Thus, the simplified expression for [tex]\sqrt{6} \times \sqrt{33} + 7[/tex] is [tex]3\sqrt{22} + 7[/tex]

Step-by-step explanation:
We have given the sequence:
-3,-14,-25,-36
We have to find the explicit formula.
The first term in this sequence is:
a₁ = -3
The common difference is:
a₂-a₁= -14-(-3) = -11
a₃-a₂ = -25-(-14) = -11
a₄-a₃ = -36-(-25)= -11
Common difference d = -11
The general formula is :
aₙ = aₙ₋₁ +d
Here d = -11 so,
aₙ = aₙ₋₁ -11 is the explicit formula.

Answer:
The correct statement is:
The slope of f(x) is same as the slope of g(x)Step-by-step explanation:
We see that the graph of the function f(x) is a line that passes through (0,2) and (1,-1)Hence, the equation of the function f(x) is calculated by a two-point formula as:
[tex]y-2=\dfrac{-1-2}{1-0}\times (x-0)\\\\y-2=\dfrac{-3}{1}\times x\\\\y-2=-3x\\\\y=-3x+2[/tex]
( On comparing the equation of f(x) with slope intercept form.
i.e. y=mx+c
where m is the slope and c is the y-intercept)
We get slope of f(x)= -3
and y-intercept= 2
The function g(x) is given by:[tex]g(x)=-3x-6[/tex]
Hence, slope of g(x) = -3
and y-intercept= -6
Hence, we get that the slope of f(x) and g(x) is same.
