Answers

Answer 1

Answer:

(-2,5)

Step-by-step explanation:

use formula: m= ([tex]\frac{x^{1}+x^{2} }{2} , \frac{y^{1}+y^{2} }{2}[/tex])

midpoint(m) equals (4,0) and C is (10,-5)

C represents [tex](x^{1} ,y^{1})[/tex] and other endpoint D represents [tex](x^{2}, y^{2} )[/tex] so:

(4,0) = [tex](\frac{10+x^{2} }{2} , \frac{-5+y^{2} }{2} )[/tex]                  

4 = [tex]\frac{10+x^{2} }{2}[/tex]

[tex]4*2 = (\frac{10+x^{2} }{2} )2[/tex]      Get rid of 2 by multiplying both sides by 2

8 = [tex]10 + x^{2}[/tex]               Subtract both sides by 10

[tex]x^{2} = -2[/tex]                x coordinate of D = -2

To find y coordinate of D:

0 = [tex]\frac{-5+y^{2} }{2}[/tex]                    Get rid of 2 by multiply both sides by 2

0 = [tex]-5 + y^{2}[/tex]                    Add both sides by 5

[tex]y^{2} = 5[/tex]                          y coordinate of D = 5

So if x-coordinate of D= -2 and y-coordinate of D=5, the coordinates for D is (-2,5)

Karen bought cupcakes for her sister's birthday party. 3 cupcakes had sprinkles on top. The other 27 cupcakes did not have sprinkles. What percentage of the cupcakes had sprinkles?

Answers

Answer:

10%

Step-by-step explanation:

so

3 cupcakes had sprinkles

27 didn't have sprinkles

which means that there are a total of 30 cupcakes, (because 3 + 27 is 30)

so then set up a proportion

part/whole = percent/one hundred

substitute in the given values

3 / 30= precent/100

simplify

1/10 = precent/100

you don't have to use cross products here because it is pretty obvious that 10 * 10 = 100 so then just multiply 1/10 by 10 and you get your answer

percent = 10

Parallel to y=-3x+4, x-intercept at 4

Answers

Answer:

y = -3x + 12

Step-by-step explanation:

The slope of parallel line is the same as the original line.

If the x-intercept is 4, this as a point can be stated as (4, 0)

We can now solve for the y-intercept.

y = -3x + b

0 = -3(4) + b

0 = -12 + b

12 = b

Put everything we solved for back into the formula [ y = mx + b ]

y = -3x + 12

Best of Luck!

1.The growth of a sample of bacteria can be modeled by the function b(t)=100(1.06)t where b is the number of bacteria and t is time in hours.

What is the number of total bacteria after 3 hours?

Answers

Given:

The growth of a sample of bacteria can be modeled by the function

[tex]b(t)=100(1.06)^t[/tex]

where, b is the number of bacteria and t is time in hours.

To find:

The number of total bacteria after 3 hours.

Solution:

We have,

[tex]b(t)=100(1.06)^t[/tex]

Here, b(t) number of total bacteria after t hours.

Substitute t=3 in the given function, to find the number of total bacteria after 3 hours.

[tex]b(t)=100(1.06)^3[/tex]

[tex]b(t)=100(1.191016)[/tex]

[tex]b(t)=119.1016 [/tex]

Therefore, the number of total bacteria after 3 hours is 119.1016.

Help Simplify 6(x + 4).

Answers

Answer:

6x+24

Step-by-step explanation:

The simplified form of the expression 6(x + 4) is 6x + 24.

We have,

To simplify the expression 6(x + 4), we can apply the distributive property of multiplication over addition.

The distributive property states that when we have a number multiplied by a sum of terms, we can distribute the multiplication to each term separately and then simplify.

In this case, we have 6 multiplied by the sum (x + 4). Applying the distributive property, we can multiply 6 by both x and 4:

6(x + 4) = 6 * x + 6 * 4

Simplifying further:

6x + 24

Therefore,

The simplified form of the expression 6(x + 4) is 6x + 24.
