I got 64,800 because you multiply 54,000 x 1.20 and that equals 64,800

Y = −1 / 4 (x + 4) 2 −1 on a coordinate plane using its vertex, focus, and directrix.

trasher [3.6K]

Answer:

Hello,

Step-by-step explanation:

do I remind you of the formula :

where (a,b) is the vertex and y=k the directrix

$y=\dfrac{(x-a)^2}{2(b-k)} +\dfrac{b+k}{2} \\\\\\y=-\dfrac{(x+4)^2}{4} -1 \\\\Using\ identification:\\a=-4\\2(b-k)=-4\\b+k=-2\\\\\left\{\begin{array}{ccc}b-k&=&-2\\b+k&=&-2\\\end{array}\right.\\\\\\\left\{\begin{array}{ccc}2b&=&-4\\2k&=&0\\\end{array}\right.\\\\\\\left\{\begin{array}{ccc}b&=&-2\\k&=&0\\\end{array}\right.\\$

Focus=(-4,-2)

Directrix: y=0

Vertex=(-4,-1)

What is the monomial if a square of a monomial is: 0.0001*a^8*x^4

Georgia [21]

Answer:

Monomial $0.0001\cdot a^8\cdot x^4$ is a square of monomial $0.01\cdot a^4\cdot x^2$

Step-by-step explanation:

Given monomial $0.0001\cdot a^8\cdot x^4$

Using property $(a^m)^n=a^{m\cdot n},$ note that

$0.0001=(0.01)^2\\ \\a^8=(a^4)^2\\ \\x^4=(x^2)^2$

So,

$0.0001\cdot a^8\cdot x^4=(0.01)^2\cdot (a^4)^2\cdot (x^2)^2.$

Now use property $(a\cdot b)^n=a^n\cdot b^n$ to rewrite the previous expression:

$(0.01)^2\cdot (a^4)^2\cdot (x^2)^2=(0.01\cdot a^4\cdot x^2)^2$

Hence, monomial $0.0001\cdot a^8\cdot x^4$ is a square of monomial $0.01\cdot a^4\cdot x^2$

Which expression has a value of 3?

Marina86 [1]

Step-by-step explanation:

3(4 *to the power of 2* - 3*to the power of 2*)

3(4²-3²)
3(16-9)
3(7)
21

24-23 x 3

24-23×3
24-69
-45

3*to the power of 3* - 3*to the power of 2

3³-3²
9-6
3

(6*to the power of 2* - 3) (9*to the power of 2* - 70)

(6²-3)(9²-70)
(36-3)(81-70)
(33)(11)
363

Hence, Option d. is the correct answer because it gives answer 3 when it is solved.

In a survey of 232 students, about 5.5% have attended more than one play. Which is closest to the number of students in the surv

dybincka [34]

Answer:

Step-by-step explanation:

Number of students that attended more than play = percentage of students that attended more than play x total number of students

5.5% x 232

0.055 x 232 = 12.76 students

to round off to the nearest whole number, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.

Since the first term is 7 which is greater than 5, 1 would be added to it.

This gives 13
