Answer:

20 square units

Step-by-step explanation:

Point D should be D(4, -1) if a rectangle is to be formed.  A picture is attached to this answer.

The rectangle's dimensions are 4 by 5, so it's area is 4 x 5 = 20 square units.  The picture is small enough that you could even just count squares inside the rectangle!

Answer:

210 different arrangements

Step-by-step explanation:

      We can use a formula to solve this problem.

Since there are only 6 positions, we are "picking 6 from a group of 10"

-> For 6! we do 6*5*4*3*2*1, etc.

10!/(6! * (10-6)!)

10!/(6! * (4)!)

10!/(6! * (4)!)

10!/17,280

3,628,800/17,280

210 different arrangements

Answer:

$13.60 cents

Step-by-step explanation:

Given the following question:

60% of 34

In order to find the answer, we will use the formula to calculate percentages to find 60% of 34. Once we find that answer we will subtract it from the initial amount.

[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{60\times34}{100} =60\times34=2040\div100=20.4[/tex]
[tex]=20.40[/tex]

Now subtract:
[tex]34-20.40=13.60[/tex]
[tex]=13.60[/tex]

After a 60% discount the item will cost "$13.60 cents."

Hope this helps.

Answer:

6 1/2

Step-by-step explanation:

[tex]2 \frac34 + 3\frac34[/tex]

Convert them to improper fractions by multiplying the whole number by the denominator of the fraction, adding this to the numerator of the fraction, then putting it over the denominator:

[tex]2 \frac34 + 3\frac34=\dfrac{2 \times 4+3}{4}+\dfrac{3 \times 4+3}{4}=\dfrac{11}{4}+\dfrac{15}{4}[/tex]

As the fractions have the same denominator, we can simply add the numerators:

[tex]\dfrac{11}{4}+\dfrac{15}{4}=\dfrac{11+15}{4}=\dfrac{26}{4}[/tex]

Convert back to a mixed number by dividing the numerator by the denominator. Writing the whole number followed by the remainder over the denominator:

[tex]\dfrac{26}{4}=6\frac24=6\frac12[/tex]

So there are two angles given in equation I.e :-

And we have to find :-

Solution:-

↬ 2x + 2 = 3x - 52

Reason:-

VOA (Vertically opposite angles)

How to recognize when angles are in voa aka Vertically opposite angles?

it's really easy by the way. when ever there a multiplication sign ( × ) either parallely or horizontally , then the opposite angles formed by them are always equal.

↬2x = 3x - 52 - 2

↬2x = 3x - 54

↬2x - 3x = - 54

↬ - x = - 54

↬ x = 54°

Now Let's Verify:

⇢ 2x + 2 = 3x - 52

put the value of x in the equation

⇢ 2(54) + 2 = 3(54) - 52

⇢ 2 × 54 + 2 = 3(54) - 52

⇢ 108 + 2 = 3(54) - 52

⇢ 110 = 3(54) - 52

⇢ 110 = 3 × 54 - 52

⇢ 110 = 162 - 52

⇢ 110 = 110

LHS = RHS

Hence verified!

Step-by-step explanation:

equal steps.

so, starting at -2 the fifth number (= after the 4th step) is 26.

so, the interval is 26 - -2 = 28 long.

28/4 = 7

so, each step is 7 long.

the third number is after the second step, that means after adding 2×7 = 14

-2 + 14 = 12

12 is the third number.

∴ He will get $755.

a) The equation [tex]V(m) = 8400 - 560\cdot m[/tex] represents the discharge of the Grand Prismatic Spring.

b) The discharge of the Grand Prismatic Spring takes 15 minutes.

c) The remaining quantity after 7 minutes is 4480 gallons.

d) The hardness of cardboard is 2.

a) In this case, the volume of water ([tex]V[/tex]), in gallons, decreases linearly in time ([tex]m[/tex]), in minutes. Then, we could model the situation by using the following expression:

[tex]V(m) = V_{o} - \dot V \cdot m[/tex] (1)

Where:

If we know that [tex]V_{o} = 8400\,gal[/tex] and [tex]\dot V = 560\,\frac{gal}{min}[/tex], then the volume of the Grand Prismatic Spring is represented by this expression:

[tex]V(m) = 8400 - 560\cdot m[/tex] (2)

The equation [tex]V(m) = 8400 - 560\cdot m[/tex] represents the discharge of the Grand Prismatic Spring. [tex]\blacksquare[/tex]

b) By (1) and [tex]V(m) = 0[/tex] we find the time required for discharge:

[tex]m = \frac{0 - 8400}{-560}[/tex]

[tex]m = 15\,min[/tex]

The discharge of the Grand Prismatic Spring takes 15 minutes. [tex]\blacksquare[/tex]

c) The quantity of gallons remaining is found by evaluating the function for [tex]m = 7[/tex]:

[tex]V(7) = 8400 - 560\cdot (7)[/tex]

[tex]V(7) = 4480\,gal[/tex]

The remaining quantity after 7 minutes is 4480 gallons. [tex]\blacksquare[/tex]

d) According to Mohs scale, the hardness of feldspar is 6. The statement indicates the following relationship, as there is a constant relationship between both hardnesses:

[tex]y = 3\cdot x[/tex] (3)

Where:

If we know that [tex]y = 6[/tex], then the hardness of cardboard is:

[tex]x = \frac{6}{3}[/tex]

[tex]x = 2[/tex]

The hardness of cardboard is 2. [tex]\blacksquare[/tex]

Answer:

Step-by-step explanation:

f(x) = x⁴ - 8x² + 16

f'(x) = 4x³ - 16x = 4(x³ - 4x) = 4x(x² - 4) = 4x(x - 2)(x + 2)

f'(x) = 0, x = 2, -2

f"(x) = 4(3x² - 4)

f''(0) = -16 < 0, f""(2) = f''(-2) 3(12 - 4) > 0

so f(2) and f(-2) are minimum values

f(0) is maximum value.

f(0) = 16, f(2) = f(-2) = 2⁴ - 8*2² + 16 = 0

Maximum = 16, minimum value = 0

-∞ < x < -2, f'(x) < 0

-2 < x < 0, f'(x) > 0

0 < x < 2, f'(x) < 0

2 < x < ∞, f(x) > 0

increase: (-2, 0) and (2, ∞)

decrease: (-∞, -2) and (0, 2)

Answer:

Step-by-step explanation:
So I will shorten Eric, and Bob's names as E, and B.

So the equations are this
B-E = B+E - 240, E as Eric, and B as Bob, and this E+B=9(E-B)
Move the variables and you get
-2E =- 240
Just divide them both by -2
and E=120
So when we know the value of E we can just plug it into the 1st question
120+B=9B+1080
Moves the Variables and numbers to the other side
8B=1200
1200/8= 150
B=150
There is Bob's weight

We are given that [tex]{\bf{\tilde{n}=2n(n+1)\:\: \forall \:\: n\in \mathbb{N}}}[/tex] and need to find the value of [tex]{\bf{\dfrac{\tilde{8}}{\tilde{2}}}}[/tex] . Now , let's find it ;

[tex]{:\implies \quad \sf \dfrac{\tilde{8}}{\tilde{2}}=\dfrac{2\times 8(8+1)}{2\times 2(2+1)}}[/tex]

[tex]{:\implies \quad \sf \dfrac{\tilde{8}}{\tilde{2}}=\dfrac{\cancel{2}\times 8(9)}{\cancel{2}\times 2(3)}}[/tex]

[tex]{:\implies \quad \sf \dfrac{\tilde{8}}{\tilde{2}}=\dfrac{8(9)}{2(3)}}[/tex]

[tex]{:\implies \quad \sf \dfrac{\tilde{8}}{\tilde{2}}=\dfrac{2\times 4\times 3\times 3}{2\times 3}}[/tex]

Cancelling 2 and 3 from denominator

[tex]{:\implies \quad \sf \dfrac{\tilde{8}}{\tilde{2}}=4\times 3}[/tex]

[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{\dfrac{\tilde{8}}{\tilde{2}}=12}}}[/tex]

Given the transformation, [tex]\~n[/tex] = 2n(n+1), on applying the solution is [tex]\frac{\~8}{\~2} = 12[/tex].

A transformation is any form of change. When one variable is given as a function of another variable, we say that the latter is transformed. We can find the value of corresponding new variable by putting in values in the old variables.

Given,

[tex]\~n[/tex] = 2n(n+1)

Given,

when n = 8

[tex]\~8[/tex] = 2 * 8 * ( 8+1) = 2*8*9 = 144

when n = 2

[tex]\~2[/tex] = 2 * 2 * ( 2+1) = 2*2*3 = 12

Thus,

[tex]\frac{\~8}{\~2} =\frac{144}{12} = 12[/tex]

Answer:

(3x5) -6 = 3x3

Step-by-step explanation:

So we know that elijah starts with 3 sets of 5 marbles each.

This can be thought of as 3 x each set, or 3 x 5.

Elijah then gives away 6 marbles from this set, or in other words subtracts 6.

How can this be put into a equation, however?

We know that we are taking 3x5, and subtracting it by 6. However it isnt as simple as 3x5-6.

It would have to be (3x5)-6, since your sets are a total of 15, or 3x5. This total is being subtracted to by 6.

This can be written as:

(3x5)-6

The only equation in your list that looks like this would be the third one, where:

(3x5)-6 = 3x3

So this would be your answer!
