Answer & Step-by-step explanation:

The equation of a circle is...

[tex](x-x1)^2+(y-y1)^2=r^2[/tex]

So all we have to do is plug in the numbers we are given.

So, the equation of the circle is (x - 7)² + (y + 3)² = √7²

Answer:

[tex](x - 7)^{2} + (y + 3)^{2} = 7[/tex]

Answer:

C

Step-by-step explanation:

Since the graph hits 0 at x = 0, your y intercept is 0.

The graph is decreasing which means you have a negative slope.

They gave you a coordinate so use it to find the slope.

[tex]\frac{1-0}{-3-0} = \frac{-1}{3}[/tex]

That's your slope.

C is the correct answer.

Answer:

D.

Step-by-step explanation:

f(5) = -25 + 40

f(5) = 15

Answer:

The answer is D) 15

Step-by-step explanation:

F(x)= 5x + 40 (substitute -5 for x)

= F(x)= 5(-5)+ 40

= F(x)= -25+40

F(x)= 15

Answer:

The number is 16.

Step-by-step explanation:

3x=32+x

2x=32

x=16

A number that when tripled, gives the same result as when 32 is added to it is 16.

In this exercise, you're required to solve for an unknown number, that when tripled has the same value as when 32 is added to it.

Translating the word problem into an algebraic expression, we have;

Tripling the number, we have:

[tex]3x[/tex]    ....equation 1

Adding 32 to the number, we have:

[tex]32 + x[/tex]   ....equation 2

Equating the two equations, we have:

[tex]3x = 32 + x\\\\3x - x = 32\\\\2x = 32\\\\x = \frac{32}{2}[/tex]

x = 16

Answer:

I would say 9

Step-by-step explanation:

range is the difference between the largest and the smallest values in a data set.  the range in this case is 3. so, we have to either add to 6 or subtract from 6.

but we've been told that Lee's shoe size is not three so it 6 + 3 = 9.

Answer:

Step-by-step explanation:

We know that a day contains 24 hours in total.

The time already passed will be represented by [tex]x[/tex].

The remaining time would be [tex]\frac{x}{2}[/tex], becasye half of what has already passed remains until the end of the day.

Basically, the sum of these two expression gives 24 hours in total.

[tex]x + \frac{x}{2} =24\\\frac{3x}{2}=24\\ x=16[/tex]

Therefore, the actual time is 4 p.m.

Only the second equation is an identity

Step-by-step explanation:

1)

[tex]1+\dfrac{\cos^2\theta}{\cot^2\theta(1-\sin^2\theta)}= \\\\\\1+\dfrac{\cos^2\theta}{\cot^2\theta(\cos^2\theta)}= \\\\\\1+\dfrac{1}{\cot^2 \theta}= \\\\\\1+\tan^2\theta=\sec^2\theta\neq 2\sec^2 \theta[/tex]

This one is not an identity.

2)

[tex]19\cos \theta\left( \dfrac{1}{\cos \theta}-\dfrac{\tan \theta}{\csc \theta} \right)= \\\\\\19\cos \theta \left( \dfrac{1}{\cos \theta}-\dfrac{\sin^2 \theta}{\cos \theta} \right)= \\\\\\19\cos \theta \left( \dfrac{1-\sin^2 \theta}{\cos \theta}\right)= \\\\\\19\cos \theta \left( \dfrac{\cos^2 \theta}{\cos \theta}\right)= \\\\\\19\cos \theta (\cos \theta)= \\\\\\19\cos^2 \theta = 19\cos^2 \theta[/tex]

This one is an identity. Therefore, only the second equation is an identity. Hope this helps!

Answer:

£151.20

Step-by-step explanation:

20%= 100%divided by 5

To find 100% from 20% you x by 5

so you times 30.24 by 5

30.24x 5 = 151.2

So the answer is £151.20

interest percentage rate would be 1.6754%

The interest rate for the account is 1.68%

The interest rate is the amount a lender charges a borrower and is a percentage of the principal the amount loaned.

Given that,

Sue invests £9000 in an account for one year.

She pays £30.24 at a rate of 20%

So, 20% of the interest = £30.24

Let the interest be x,

X0.2 = 30.24

X = £151.2

The total interest was = £ 151.2

The rate R at which generated this interest =

R = (100 × 151.2)/(1 × 9000)

R = 15120/9000

R = 1.68%

Hence, the interest rate = 1.68%

Answer:

(C)7b

Step-by-step explanation:

Given the expression:

[tex]\dfrac{7}{3}ab-\dfrac{7}{6}b[/tex]

Let us factor the expression:

[tex]=\dfrac{7b}{3}\left(a-\dfrac{1}{2}\right)[/tex]

Since we need the greatest common factor, we can rewrite the expression as:

[tex]7b\left(\dfrac{1}{3}a-\dfrac{1}{6}\right)[/tex]

Therefore, the greatest common factor is 7b.

The correct option is C.

Answer: C. 7 b

Answer:

y=4x-4

Step-by-step explanation:

Since this line rises 4 units for every 1 it moves to the right, it has a slope of 4/1=4. Also, since it intersects the y axis at the point (0,-4), b=-4.

Therefore, the equation is y=4x-4. Hope this helps!

Answer:

(B) (22.5, -12.5)

Step-by-step explanation:

When the point [tex](9,-5)[/tex] is dilated by with a scale factor of 2.5

In a dilation, when its scale factor is less than 1, the pre-image will be lesser than the image.

However, when the scale factor is greater than 1, the pre-image will be greater than the image.

The Image of the dilation of [tex](9,-5)[/tex] with a scale factor of 2.5 is therefore:

[tex](9*2.5,-5*2,5)\\=(22.5, -12.5)[/tex]

The correct option is B.

[tex]P=0.0625[/tex]

Step-by-step explanation:

The probability of getting one tails is a half.

The probability of getting another tails given you had a tails is:

[tex]\frac{1}{2}*\frac{1}{2}=(\frac{1}{2})^2=\frac{1}{4}[/tex]

The probability of getting n tails in general is given by:

[tex](\frac{1}{2})^n = \frac{1}{2^n}[/tex]

So, when we have four tails - our value for n is four.

[tex](\frac{1}{2})^4=\frac{1}{2^4}=\frac{1}{16}=0.0625[/tex]
