Answer 1

Answer: $1. \ \ \ (k+7)^2 =289\n\n\Leftrightarrow\ \ \ k+7= √(289) \ \ \ or\ \ \ \ k+7=- √(289)\n\nk=17-7=10\ \ \ \ \ \ \ or\ \ \ \ k=-17-7=-24 \n\n2.\ \ \ (2s-1)^2 =225\n\n\Leftrightarrow\ \ \ 2s-1= √(225) \ \ \ or\ \ \ \ 2s-1=- √(225)\n\n2s=15+1\ \ \ \ \ \ \ or\ \ \ \ 2s=-15+1\n2s=16\ \ \ \ \ \ \ \ \ \ \ \ or\ \ \ \ 2s=-14\ns=8\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ or\ \ \ \ s=-7 \n\n$

$3.\ \ \ (x-4)^2 =169\n\n\Leftrightarrow\ \ \ x-4= √(169) \ \ \ or\ \ \ \ x-4=- √(169)\n\nx=13+4=17\ \ \ \ \ \ \ or\ \ \ \ x=-13+4=-9$

Answer 2

Answer: $(k+7)^2 =289\n |k+7|=17\n k+7=17\vee k+7=-17\n k=10 \vee k=-24$

$(2s-1)^2 =225\n |2s-1|=15\n 2s-1=15\vee 2s-1=-15\n 2s=16 \vee 2s=-14\n s=8 \vee s=-7$

$(x-4)^2 =169\n |x-4|=13\n x-4=13 \vee x-4=-13\n x=17 \vee x=-9$

Answer:

Rita sells 6 tickets for a school fundraiser. The total price 6 tickets is $84 . Find the price of one ticket.

6 tickets = $84

1 ticket = $84/6 = $14

Write and solve an equation where the variable is not alone, and be sure to define your variable

Y = total price

X = number of tickets

Y = 14X

$84 = 14X

$84/14 = X

6 = X

Answer:

The volume of a cone is $452.16\ cm^3$ .

Step-by-step explanation:

We have,

Radius of a cone is 6 cm and its height is 12 cm

It is required to find the volume of a cone. Volume of a cone is given by :

$V=(1)/(3)\pi r^2 h$

r is radius

h is height

Plugging all the given values in the above formula,

$V=(1)/(3)* 3.14*(6)^2* 12\n\nV=452.16\ cm^3$

So, the volume of a cone is $452.16\ cm^3$ .

Answer:

The volume of a cone is kp;m

The polynomial y² – 3y + 12 is trinomial with a degree of 2. Therefore, option C is the correct answer.

The given polynomial is y² – 3y + 12.

What is polynomial?

An expression of more than two algebraic terms, especially the sum of several terms that contain differentpowers of the same variable(s).

Here, the polynomial y² – 3y + 12 is trinomial with a degree of 2

Therefore, option C is the correct answer.

Answer:

Step-by-step explanation:

y^2 - 3y + 12

It has 3 terms (y^2) and (-3y) and (12)...therefore, it is a trinomial.

The degree of a polynomial with 1 variable is the highest exponent...so it has a degree of 2. But if it had more then 1 variable, it would be different.

answer is : trinomial with a degree of 2
