QUESTION 1 Given the equation of the circle (x + 7) + (y – 5) 2 = 64, identify the center.

Mathematics

Answer:

center=(-7,5)

Step-by-step explanation:

The center form of the circle equation is in the format (x – h)^2 + (y – k)^2 = r^2, with the center being at the point (h, k).

you can find center by making equal to zero each term, then:

x+7 = 0

x=-7

y-5 = 0

y=5

then the center is (-7,5).

1-Describe the error in the way the calculation of the slope of the two points is set up and/or solved. Please be specific. Do n
Bad White [126]

Answer:

Please check explanations for answer

Step-by-step explanation:

Let’s have two points (5,10) and (15,20)

1. Let’s find the slope of these two points

Mathematically, the slope can be calculated using the formula;

m = (y2-y1)/(x1-x2)

So m = (20-10)/(5-15) = 10/-10 = -1

The error here is the formula used in calculating the slope

The formula should be;

m = (y2-y1)/(x2-x1) and not x1-x2

2. To calculate the slope correctly, we have;

m = (y2-y1)/(x2-x1)

So the slope will be;

m = (20-10)/(15-5) = 10/10 = 1

In the point slope form, the equation can be represented as;

y-y1 = m(x-x1)

Let’s use the point (5,10)

y- 10 = 1(x-5)

The above is the point slope form

using one of the points and the correct slope of the line

Can someone figure this out?
ZanzabumX [31]

well, let's see the 10-pack is $15.37 BUT each of those 10 bars are 2.1 oz, so for the whole package you're getting really 10 * 2.1 = 21.0 oz.

the 12-pack costs $15.35 BUT each of those 12 bars are 1.4 oz, so for the whole package you're getting 12 * 1.4 = 16.8 oz.

which is the better deal?  which one gives you more ounces for the money?  after all, you're going to eat the bars, so you want more ounces, not more bars.

\bf \cfrac{15.37}{21}\cfrac{\$}{oz}~~\approx ~~0.73~\frac{\$}{oz}~\hspace{10em} \cfrac{15.35}{16.8}\cfrac{\$}{oz}~~\approx ~~0.91~\frac{\$}{oz}


so clearly you'd want to get the cheapest one with more ounces, so at $0.73 or 73 cents for each ounce, the 10-pack is the cheapest.

grin007 [14]

Answer:

40,885,048

Step-by-step explanation:

first find 3^12 and then find 7^9.

3^12 = 531,441

7^9 = 40,353,607

Add these together and you'll get 40,885,048.

Welcome! Hope this helps.

Find the height of triangle
Sophie [7]

Answer:

60

Step-by-step explanation:

First, divide 120 by two and get 60. Now do 120-60 to get 60. Set up proportion

60/x = x/60.

Cross multiply

x^2 = 3600

and now find the square root of 3600

60
