1. Express the following expression in the form y = a(x - h)? + k
y = - x² + 4x +1​

Answers

Answer 1

Answer:

Step-by-step explanation:

y = -x² + 4x + 1

factor out the leading coefficient

y = -(x² - 4x) + 1

complete the square

y = -(x² - 4x + 2²) + 2² + 1

y = -(x-2)² + 5

Answers

Answer:

y/-3 = 1/6

y = 1/6 × 3

y = 0.5

Answer:

-1/2 and -0.5

Explanation :

Hey! Ok so you will plug in all the value in the y to find out if it equals to 1/6.

y ÷ -3 = 1/6

0.5 ÷ -3 = 1/6

-1/6 = 1/6 ---> NO

y ÷ -3 = 1/6

-1/2 ÷ -3 = 1/6

1/6 = 1/6 ---> YES

y ÷ -3 = 1/6

-0.5 ÷ -3 = 1/6

1/6 = 1/6 ---> YES

y ÷ -3 = 1/6

-18 ÷ -3 = 1/6

6 = 1/6 ---> NO

Yes, it’s a solution. First you plug in -2 for x and -4 for y. 5(-2) is -10 and -2(-4) is positive 8. Add -10 to 8 and you’ll get -2 which is what you should get if the ordered pair is a solution. Hope this helps

4/3 (3x-12)=2x+8 what is x

Answers

The answer is, X = 12.

hope it helps.

Answer:

x = 12

Step-by-step explanation:

simlify 4/3 * (3x-12)

4x - 16 = 2x + 8

combine like terms, so subtract 2x by 4x

2x - 16= 8

then finish combining like terms, so 16 plus 8

2x = 24

divide 24 by 2

x = 12

Talia grouped the terms and factored out the GCF of the groups of the polynomial 15x2 – 3x – 20x + 4. Her work is shown below.

(15x2 – 3x) + (–20x + 4)
3x(5x – 1) + 4(–5x + 1)
Talia noticed that she does not have a common factor. What should she do?

Talia needs to leave the polynomial as is because it is prime and cannot be factored.
Talia needs to group the terms differently.
Talia needs to factor out a negative from one of the groups so the binomials will be the same.
Talia needs to apply the distributive property to get the expression (3x + 4)(5x – 1).

Answers

Answer:

Talia needs to factor -1 out of one of the two binomials

Step-by-step explanation:

She could take:

3x(5x - 1) + 4(-5x + 1)

and rewrite it as:

3x(5x - 1) - 4(5x - 1)

= (3x - 4)(5x - 1)

2 cot^2t sin t - cot^2t = 0

Answers

2 cot²(t ) sin(t ) - cot²(t ) = 0

cot²(t ) (2 sin(t ) - 1) = 0

cot²(t ) = 0   or   2 sin(t ) - 1 = 0

cot(t ) = 0   or   sin(t ) = 1/2

cos(t ) / sin(t ) = 0   or   sin(t ) = 1/2

cos(t ) = 0   or   sin(t ) = 1/2

[t = cos⁻¹(0) + 2   or   t = cos⁻¹(0) - π + 2]

  or   [t = sin⁻¹(1/2) + 2   or   t = π - sin⁻¹(1/2) + 2]

(where n is any integer)

t = π/2 + 2   or   t = -π/2 + 2   or   t = π/6 + 2   or   t = 5π/6 + 2

Note that the first two families of solutions overlap and can be condensed, so that

t = π/2 +   or   t = π/6 + 2   or   t = 5π/6 + 2

You and a friend go to Tacos Galore for lunch. You order three soft tacos and five burritos and your total bill is $17.75. Your friend orders four soft tacos and two burritos and paid $12.00.

Answers

Answer:

Step-by-step explanation:

let tacos be x and burritos be y

so, your 1st eqn. is 3x + 5y = 17.75

2nd eqn. is 4x+ 2y = 12

Solving the 2 eqns: Multiply eqn 1 with 2 and eqn 2 with 5

So: 6x+10y=35.5

-20x-10y=-60

=-14x=-24.5

x=24.5/14 = 1.75

Substituting the value of x in eqn 1 : (3*1.75)+5y=17.75

y = 2.5

The surface area of the cone is 16π square units.

What is the surface area of the cone?

The surface area of the cone is given by;

⇒ Area = πrl + πr²

Here, We have;

A right cone has a slant height of 6 and a radius of 2.

Substitute all the values in the formula

⇒ Area = πrl + πr²

⇒ Area = π x 2 x 6 + π x 2²

⇒ Area = 16π

Hence, The surface area of the cone is 16π square units.
