The equation of a circle, centre (a, b), radius r is given by (x - a)² + (y - b)² = r².

Answer:

D

Step-by-step explanation:

Substituting any value of x does not make the expressions equivalent. Replacing x for any two different values would equate to different unequal values.

Answer:

-s-6>-7

Step-by-step explanation:

Just ask!

Hope this helps. :)

Answer:

-s-6>-7 (top right)

Step-by-step explanation:

s = -18         > means what is on the left is bigger than what is on the right

top right one = - s - 6 ­> - 7

top right one = - ( - 18) - 6 > -7

top right one = 18 - 6 > -7

top right one = 12 is bigger than -7

Answer:

John is correct

Step-by-step explanation:

Let's solve the inequality:

[tex]3x-5\geq28[/tex]

[tex]3x\geq33[/tex]

[tex]x\geq11[/tex]

As we can see, the value of x can be either 11 or anything greater than 11. Since 12 is included in that solution set, John is correct.

Step-by-step explanation:

Equivalent equations are equations of equal values

The system of equations from the given equation are:

[tex]y= \log_2(2x)[/tex] and [tex]y=3\log_4(x)[/tex]

The logarithmic equation is given as:

[tex]\log_4(x^3) = \log_2(2x)[/tex]

Split the above equation as follows:

[tex]y = \log_4(x^3)[/tex]

[tex]y= \log_2(2x)[/tex]

Rewrite [tex]y = \log_4(x^3)[/tex] as:

[tex]y=3\log_4(x)[/tex]

Hence, the system of equations from the given equation are:

[tex]y= \log_2(2x)[/tex] and [tex]y=3\log_4(x)[/tex]

Answer: 55% of 180, 12% of 700, and 30% of 260.

Step-by-step explanation:

55% of 180 = 99…

30% of 260 = 78…

and 12% 700 = 84…

Answer:

55% of 180 > 12% of 700 > 30% of 260

Step-by-step explanation:

55% of 180 = 99

30% of 260 = 78

12% of 700 = 84

It came 26 by above calculation.

Answer:

11 luv:)

Step-by-step explanation:

Option C is correct.

Given to us:

female gazelles[tex](x)[/tex] can be maximum of 12 only. therefore,

Condition 1 is  [tex]12\geq x>0[/tex].

while,

male gazelles[tex](y)[/tex] should be exactly 3 times more than females to thrive. therefore,

Condition 2 is [tex]36\geq y>0[/tex].

There is only one option among all the options available which is satisfying both the conditions. therefore, option C is the correct option.

Answer:

I think this is what you want:

2(6)-2x=3

We then see that 2(6) and 2(x) have two in common as a "coefficient" you could say, so we distribute and put parentheses around it.

2(6-x)=3

6-x=3/2

-x=-9/2

x=9/2

Answer:

O V=202-6x; $94

Step-by-step explanation:

202 needs to be placed before the 6, eliminating options 1 and 2. It can't be option 4 because thats more than 202, leaving us with option 3. Check you answer by replacing x with 18. O V=202-6(18) ->O V=202-108 -> 202-108=$94.

Step-by-step explanation:

first question --> area of circle ---> [tex]\pi r^{2}[/tex] ---> [tex]1.5^{2} \pi[/tex] ---> [tex]2.25\pi[/tex]

second question --> unclear quetion but I assume 4?

third question --> area of cylinder --> [tex]r^{2} \pi h[/tex] --> [tex]2.25\pi h[/tex] --> [tex]2.25\pi 4[/tex] --> [tex]9\pi[/tex]

h --> height

r --> Radius

[tex]\pi[/tex] --> pi

The total surface area of the can is 61.23 square inches

The formula for calculating the total surface area of a can is expressed as:

S = 2πr(r+h)

where:

h is the height

r is the radius

Given the following parameters

h = 5in

r = 1.5in

S = 2(3.14)(1.5)(1.5 + 5)

S = 6.28(1.5)(6.5)

S = 61.23 square inches

Hence the total surface area of the can is 61.23 square inches
