we know that

The rule of the translation is

(x,y) -----> (x-4,y+4)

That means ----> The translation is 4 units at left and 4 units up

Find out the coordinates of the pre-image

Observing the figure

J(1,0),N(5,0),M(5,-3),P(2,-5)

Find out the coordinates of the image

Applying the rule of the translation at the coordinates of pre-image

J(1,0) -----> J'(1-4,0+4)

J(1,0) -----> J'(-3,4)

N(5,0) ---> N'(5-4,0+4)

N(5,0) ---> N'(1,4)

M(5,-3)----> M'(5-4,-3+4)

M(5,-3)----> M'(1,1)

P(2,-5) ----> P'(2-4,-5+4)

P(2,-5) ----> P'(-2,-1)

therefore

The coordinates of the image (after the transformation) are

J'(-3, 4), N'(1, 4), M'(1, 1), P'(-2, -1)

Answer:

:Option C J'(-3, 4), N'(1, 4), M'(1, 1), P'(-2, -1)

Answer:

$29.77

Step-by-step explanation:

First, divide 429 by 33 to find how many gallons that she's paying for, then multiply that by $2.29 to find the answer.

The cost for Carmen to drive 429 miles is $29.77.

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

Given that,

Distance car travels per gallon = 33 miles per gallon

Cost of gasoline per gallon = $2.29 per gallon.

33 miles can be travelled with 1 gallon of gasoline.

1 mile can be travelled with 1/33 gallon of gasoline.

429 miles can be travelled with 429/33 = 13 gallon of gasoline.

Amount of gasoline needed for 429 miles = 13 gallon.

Cost of gasoline for 1 gallon = $2.29

Cost of gasoline for 13 gallon = 13 × $2.29 = $29.77

Hence it will cost $29.77 for her to drive 429 miles.

While solving the quadratic equation, in the step 2, Priya did not correctly complete the square.

A quadratic equation is of the form of ax²+bx+c=0.

The given quadratic equation is of the form:

x²-6x-11=0

Now solving it by completing the square we get:

or, x²-6x=11  (take all the variable to one side)

or, x²-6x+9=11+9  (complete the square when b=3)

or, (x-3)²=20     (factor and square the polynomial)

Answer:

8.9

Step-by-step explanation:

When given the area of the rectangle to be 59.63m2.....AND the length to be 6.7m

To calculate the area of a rectangle = L×B

Width = Area ÷ Length

= 59.63m2 ÷ 6.7m

Width = 8.9m

Answer:

width = 8.9 meters

Step-by-step explanation:

Area of a rectangle = length * width

In this case:

Width = Area of a rectangle / length

Width = 59.63m² / 6.7m

Width = 8.9 m

The length of BC to the nearest while meters is 143m

Given the following parameters

AC = 108 m

<A = 53°

Using the SOH CAH TOA identity

tan 53 = opp/hyp

tan53 = BC/108

Determine the measure of BC

BC = 108tan53

BC = 143.32m

After solving the inequality we get the value of x as x ∈ (₋5,3)

Given the inequality is 2 |x + 1|  < 8

Divide both sides of the inequality by the coefficient of variable.

|x + 1| < 8/2

Reduce the fraction

|x + 1| < 4

Now convert the absolute inequality to standard inequality.

₋4 < x₊1 < 4

separate compound inequalities into system of inequalities.

x ₊ 1 > ₋4  (1)

x ₊ 1 < 4 (2)

for (1) x ₊ 1 > ₋4

rearrange variables to the left side of the equation.

x > ₋4 ₋1

calculate the sum.

x > ₋5

for (2) x ₊ 1 < 4  (2)

rearrange the terms.

x < 4 ₋ 1

x < 3

therefore ₋5 < x < 3

First of all we know about the Estimation.

What is the Estimation?

To estimate the result of multiplication (product), round the numbers to some close numbers that can easily multiply . One method of estimation is to round all factors to the biggest digit (place value) they have.

General rule for rounding:

1 ) If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

2 ) If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.

So the last digit of number is 44 which is less then 50 so the number is down to its 10's.

thats the reason why when we estimate the product of 416x9 =3,744 is 3,600.

The slope or gradient of a line is a number that describes both the direction and the steepness of line. The equation in point slope form if (-1,2) is a point on the line and 1/4 is the slope is y-2=[tex]\frac{1}{4}x+\frac{1}{4}[/tex].

A number that identifies the direction and steepness of a line is its slope or gradient. Letter m is frequently used to represent the slope.

The ratio of "vertical change" to "horizontal change" between (any) two unique points on a line is used to compute slope. Occasionally, the ratio is written as a quotient (also known as a "rise over run"), which produces the same number for every two unique points on the same line. A declining line has a negative "rise." The line might be useful, as determined by a road surveyor, or it might appear in a diagram that represents a road or a roof as a description or a design.

Given,

x1= -1

y1= 2

slope= 1/4

Substituting the values in the equation,

y-y1= m(x-x1)

y-2= [tex]\frac{1}{4}[/tex](x+1)

The 32 week gestation's period baby weighs 0.31 standard deviations below the mean.

The 41 week gestation's period baby weighs 0.65 standard deviations below the mean.

The 41 week gestation's period baby weighs relatively less.

Step-by-step explanation:

Normal model problems can be solved by the zscore formula.

On a normaly distributed set with mean  and standard deviation , the z-score of a value X is given by:

The zscore represents how many standard deviations the value of X is above or below the mean .

Find the corresponding z-scores.

Babies born after a gestation period of 32 to 35 weeks have a mean weight of 2700 grams and a standard deviation of 800 grams. A 32-week gestation period baby weighs 2450.

Here, we have .

So

A negative z-score indicates that the value is below the mean.

So, the 32 week gestation's period baby weighs 0.31 standard deviations below the mean.

Babies born after a gestations period of 40 weeks have a mean weight of 2900 grams and a standard deviation of 385 grams. A 41 week gestation period baby weights 2650 grams.

Here, we have

So, the 41 week gestation's period baby weighs 0.65 standard deviations below the mean.

Which baby weighs relatively less?

The 41 week gestation's period baby has a lesser z-score, so this means that he weighs relatively less.

The required value of a is 2 if ​the coefficient of x² is 1104 of the expansion (1 + ax)²⁴.

According to the binomial theorem, it is possible to expand any non-negative power of binomial (x + y) into a sum of the form,

(x+y)ⁿ = ⁿC₀xⁿy₀ + nC₁ xⁿ⁻¹y₁ + nC₂ xⁿ⁻² y2 + ... + nC x¹yⁿ⁻¹ + nCn x°yⁿ

where n ≥ 0 is an integer and each ⁿCₓ is a positive integer known as a binomial coefficient.

We have been given that the expansion as

(1 + ax)²⁴

As per the binomial theorem expansion of the term 3,

T₃ = ⁿC₂ a² x²

Since the coefficient of x² = 1104

⇒ n!/2!(n-2)a² x² = 1104

Here n = 24

⇒ 24!/2!(24-2)a² = 1104

⇒ 276a² = 1104

⇒ a² = 1104/276

⇒ a² = 4

⇒ a = 2

Answer:

  52 ounces

Step-by-step explanation:

You want the number of ounces of pure acid to be added to 300 ounces of 12% acid solution to produce a solution that is 25%.

Let x represent the number of ounces of acid added. Then the amount of acid in the desired solution is ...

  12%(300) +100%(x) = 25%(300 +x)

Subtracting (25%(x) +12%(300)) from both sides, we get ...

  75%(x) = 13%(300)

Dividing by the coefficient of x, we find ...

  x = (13)(300)/75 = 52

52 ounces of pure acid should be added to make a 25% acid solution.

__

Additional comment

In the original solution, there are 12%(300) = 36 ounces of acid. In the 352 ounces of final solution, there will be 36+52 = 88 ounces of acid, a proportion of 88/352 = 1/4 = 25%.

Answer:

The distance between the two given points is equal to √85.

Step-by-step explanation:

Let's recall what the distance formula is:

\displaystyle \huge\math\boxed{d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2} }\math

d= (x 1 −x2 ) 2 +(y 1 −y 2) 2

We are defined our two points as:

(x₁, y₁) → (1, -7)

(x₂, y₂) → (7, 0)

We can rewrite this into our different "variables":

x₁ = 1

y₁ = -7

x₂ = 7

y₂ = 0

Now given our distance formula and our variables, we can find the distance between the two points:

\begin{gathered}\displaystyle\huge\begin{aligned}d & = \sqrt{(1 - 7)^2 + (7 - 0)^2} \\& = \sqrt{(-6)^2 + (7)^2} \\& = \sqrt{36 + 49} \\& = \math\boxed{\sqrt{85}} \\\end{aligned}\end{gathered}

d= (1−7) 2+(7−0) 2= (−6) 2+(7) 2 = 36+49=\math 85

∴ since the radical is already in its simplest form, our distance between the two points is equal to √85.

Hope this helps!
