someone, please (calmly) tell me if I'm wrong and I will try to fix it.

Answer:

[tex]x \geqslant 4[/tex]

The expression above means x can be any number starting from 4 and above .

let's see what to do...

Figure A is scaled image of Figure B.

So Figure A must be made in a proportion of Figure B.

We should find the ratio:

to find the ratio we have to use the same known sides.

[tex]ratio = \frac{5}{2} \\ [/tex]

Also we have :

[tex]ratio = \frac{12.5}{x} \\ [/tex]

So we have :

[tex] \frac{5}{2} = \frac{12.5}{x} \\ [/tex]

Multiply the sides by 2x :

[tex]5 \: x = 25 \\ x = 5[/tex]

And we're done.

Thanks for watching buddy good luck.

Answer:

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]

From the question the points are

(5,−3) and (5, 8)

The slope is

[tex]m = \frac{8 - - 3}{5 - 5} = \frac{8 + 3}{5 - 5} = \frac{8}{0} \\ [/tex]

Since every number divided by zero is undefined the slope of the line is also undefined.

Hope this helps you

Answer:

1) p=1/2

2) V(p)=25

Step-by-step explanation:

We have the function:

[tex]V(p)=100p(1-p)[/tex]

Which represents the variance of the number of left handed people in a group of 100.

Question 1)

We want to find the value of p that maximizes the variance.

Let's examine our function. We can see that it is a quadratic. Therefore, the value of p that maximizes the variance will simply be the x-coordinate of the vertex of our equation.

Let's expand our function:

[tex]V(p)=100p(1-p)[/tex]

Distribute:

[tex]V(p)=100p-100p^2[/tex]

Let's find the vertex of our equation. We can use the following formulas (I switched out the x for p):

[tex]p=-b/2a,\ V(-b/2a)[/tex]

Let's determine our coefficients. The "a" is the coefficient in front of the squared term and "b" is the coefficient in front of the x term.

So, a is -100, and b is 100.

Substitute them into our formula:

[tex]p=-(100)/2(-100)[/tex]

Multiply:

[tex]p=100/200[/tex]

Divide:

[tex]p=1/2[/tex]

So, the x-coordinate (or rather p in this case) of our vertex is 1/2.

To find the y-value, let's substitute it back into our function. We have:

[tex]V(p)=100p-100p^2[/tex]

Substitute 1/2 for p:

[tex]V(1/2)=100(1/2)-100(1/2)^2[/tex]

Evaluate:

[tex]V(1/2)=50-25=25[/tex]

Therefore, our vertex is:

[tex](1/2, 25)[/tex]

So, the value of p that maximizes our variance is p=1/2.

Question 2)

We want to find the maximum variance.

Again, this will simply be the vertex of our quadratic.

This time, it will be the y-coordinate.

We can see that the y-coordinate of the vertex is 25.

So, our maximum variance is V(p)=25.

And we're done!

Answer: 50,562 people

Step-by-step explanation:

The city population in the beginning of 1953 was 9,903.

Grows at 5.4% each year.

Population in beginning of 1984 can be acquired through compound interest.

Periods = 1984 - 1953 = 31 years

Population in 1984 = 9,903 * (1 + 5.4%)³¹

= 9,903 * 5.1057428421476776548111

= 50,562 people

Answer:

y = 5x-2

Step-by-step explanation:

5x - y = 2

Subtract 5x from each side

5x - y -5x = 2 -5x

-y = -5x+2

Multiply each side by -1

y = 5x-2

Answer:

[tex]y=-2+5x[/tex]

Step-by-step explanation:

[tex]5x-y=2\\\\5x-5x-y=2-5x\\\\-y=2-5x\\\\\frac{-y=2-5x}{-1}\\\\ \boxed{y=-2+5x}[/tex]

Hope this helps.

Extra note: Another correct answer would be [tex]y=5x-2[/tex]

Answer: B

Step-by-step explanation:

The amount of weight barbell acting on a weight lifter os 80 N.

Answer:

Each would equal 10 lbs.

Step-by-step explanation:

60 pounds all together is the weight of 6 boxes, so if you divide 60 by 6, you'll get 10 lbs for each box.

Answer:

each box weighs 10lbs

Step by Step explanation:

if you do 10 20 30 40 50 60 70.... you will see what times what gives you 60 which in this case it is what times 6 gives you 60 so if you list your 6s you will will go until you  get to 6*10 which is 60 but you can do a list of your 10s it is easier that away to be honest. I hope this answer helps you:)

Answer:

Step-by-step explanation:

1/10 is literally 1 tenth of something. so 10% of x = 43.95 so 100% of x = 43.95 * 10 so x = 439.5

4n-1

7-3=4 (term to term sequence)

3-4=-1

Answer:it’s 4n - 1

Step-by-step explanation: you do 7 - 3 = 4 and then 4 - 3 = -1

Answer :

Let the first term of both the terms be [tex]\: \sf \: x _1 \: \: \& \: \: x _2[/tex] and last term be [tex]\: \sf \: y _1 \: \: \& \: \: y_2\\ [/tex]

Now, by using the mid point formula to find the mid point of the segment -

[tex] \\ \sf \bigg( \frac{x_1 + x_2}{2} , \: \frac{y_1 + y_2}{2} \bigg) \\ [/tex]

Now, by substituting the values of both x and y -

[tex] \\ \sf \bigg( \frac{ - 7 + 6}{2} , \: \frac{ - 9 + 3}{2} \bigg) \\ [/tex]

Adding -7 and 6 -

[tex] \\ \sf \bigg( \frac{ - 1}{2} , \frac{ - 9 + 3}{2} \bigg) \\ [/tex]

Now, move the negative in front of the fraction -

[tex] \\ \sf \bigg( \frac{ - 1}{2} , \frac{ - 6}{2} \bigg) \\ \\ \\ \sf \bigg( \frac{ - 1}{2} , - 3\bigg) \\ [/tex]

Answer:

it's not what the fraction is equal to its asked me which said it would give you the answer and by the way it's 8 / 8

Answer:

  5.  4√2 N

  6. 20 N

Step-by-step explanation:

We're not sure how your diagram relates to the notion of the weight being "pushed". Usually T represents "tension," which would indicate a "pull" in up and to the right.

__

5. The side ratios in this triangle match exactly those in your problem 1. T is √2 times the equal side lengths, so is T = 4√2 N.

__

6. The sides ratios in the triangle match exactly those in your problem 2. T is 2 times the shorter side length, so is T = 20 N.

Answer:

I know only one

x=14 being vertically opposite angles

Step-by-step explanation:

algle FGE = GEC

FGE = 180 - (14 + 78)°

= 88°

so angle GEC = 88°

4x + 88 = 180

4x = 180 - 88

4x = 92

x = 92/4

= 23

Answer:

x = 11.8639

Step-by-step explanation:

cos∅ = adjacent / hypotenuse

Since we are dealing with right triangles, we can use trig to help solve for missing values:

cos22° = 11/x

xcos22° = 11

x = 11/cos22°

x = 11.8639

therefore, the answer is 9.

Answer:

a/b = a * 1/b

Step-by-step explanation:

a/b = a * 1/b

this looks easy....

But what about

a / (1/b) = a*b

if you see any division, you can always multiply BOTH the numerator AND the denominator by the same amount. That is allowed because that is the same as multiiplying by the number 1.

So multiply by b/b and see what happens.

a / (1/b) = b/b * a / (1/b)

group the numerator AND the denominator

a / (1/b) = (b * a ) / b*(1/b)

a / (1/b) = (b * a ) / b/b

a / (1/b) = (b * a ) / 1

a / (1/b) = (b * a )

a / (1/b) = a*b

It is allowed because you can always multiply any number by 1 and that is because that will not change the original number. The number multiplied by 1 remains the same number.

This notion is very powerful and it can be used to turn any division into a multiplycation, and vice versa.

a / (1/b) = a*b

Answer:

This equation generalizes the patterns seen in part D, where a and b represent real numbers:

(a + bi)(a − bi) = a2 + b2.
