C.36 x 10^6
D. 6 x 10^9 ANYONE PLEASE HELP ME WITH MY MATH HOMEWORK I REALLY NEED THE ANSWER RIGHT NOW BECAUSE I HAVE TO PASS THIS TOMORROW I HOPE Y'ALL CAN HELP ME:(I'LL MARK BRAINLIEST FOR THOSE WHO CAN ANSWER IT CORRECTLY! PS: DON'T WASTE MY POINTS PLEASE I WORK HARD FOR THIS POINTS IF YOU DON'T KNOW THE ANSWER CARE TO IGNORE:)
Answer:
C: 36 × 10^6 m²
Step-by-step explanation:
Given the side length of a square = 6 × 10³m,
To solve for the area of a square, use the following formula:
A = S² where:
S = side of the square
Substitute the given value for the side into the formula:
A = S²
A = (6 × 10³)²
A = 36000000 or 36 × 10^6 m²
NOTE:
6 × 10³ is also the same as 6 × 1000 = 6000,
(6 × 10³)² is essentially 6,000² = 36,000,000
Therefore, the correct answer is C) 36 × 10^6
value of 3a – 5b when a = –4 and b = 2 .

The unit measure for atmospheric pressure is kPa (Kilo-Pascals). At sea level the standard
atmospheric pressure is 101.3 kPa. For every 1000 feet increase in altitude, atmospheric
pressure decreases by 1.8 kPa. What is the atmospheric pressure at 50,000 feet?
The pressure change is an illustration of an arithmetic progression.
The atmospheric pressure at 50000 feet is 11.3 kPa
The given parameters are:
[tex]\mathbf{a = 101.3}[/tex] --- the first term
[tex]\mathbf{d = -1.8 per 1000}[/tex] -- common difference
At 50000 feet, the number of increment in altitude is
[tex]\mathbf{n = \frac{50000}{1000}}[/tex]
[tex]\mathbf{n = 50}[/tex]
So, the atmospheric pressure at 50000 feet is:
[tex]\mathbf{T_{50} = 101.3 - 1.8 \times 50}[/tex]
[tex]\mathbf{T_{50} = 101.3 - 90}[/tex]
[tex]\mathbf{T_{50} = 11.3}[/tex]
Hence, the atmospheric pressure at 50000 feet is 11.3 kPa

pls help...
Answer:
The identity sinA sin(A+2B) - sinB sin(B+2A) = (sinA)^2 - (sinB)^2 is proved below.
Step-by-step explanation:
sinA sin(A+2B) - sinB sin(B+2A) =
sinA ( sin(A) cos(2B) + sin(2B) cos(A) ) - sinB (sin(B)cos(2A) + sin(2A)cos(B) ) =
sinA( sinA [cos^2(B)- sin^2(B)] + 2 sin(B) cos(B) cosA ) - sinB( sinB(cos^2A-sin^2A)+2 sinA cosA cos(B) ) =
sin^2A(cos^2B-sin^2B) + 2 sinB cosB sin(A) cos(A) - sin^2B(cos^2A-sin^2A) - 2 sinA sinB cosA cosB =
sin^2A(cos^2B-sin^2B) - sin^2B(cos^2A-sin^2A) =
sin^2Acos^2B - sin^2Asin^2B - sin^2Bcos^2A + sin^2Bsin^2A =
sin^2Acos^2B - sin^2Bcos^2A =
(1 - cos^2A)(cos^2B) - (1 - cos^2B)(cos^2A) =
cos^2B - cos^2A cos^2B - cos^2A + cos^2B cos^2A =
cos^2B - cos^2A =

Step-by-step explanation:
A local pizza shop has a membership program for frequent buyers. The membership costs $15 per month and members get a discounted price of $2 per slice of pizza. Anna purchased a membership to this pizza shop. How much would Anna have to pay the pizza shop if she bought 11 slices of pizza this month? What would be the monthly cost for xx slices of pizza
Answer:
$37
2x+15=y
Step-by-step explanation:
2x+15=y would be the function for any member's cost to be figured.
In Anna's case, if she bought 11 slices of pizza for $2 each and paid for her monthly membership of $15 then the equation would be
2(11)+15=
2x11=22
22+15=37
Her cost for that month would be $37

What is the five ordered pairs and completing the input/output table
Answer:
{(0, -4), (1, -2), (2, 0), (3, 2), (4, 4)}
Input values (x) = {0, 1, 2, 3, 4}
Output values (y) = {-4, -2, 0, 2, 4}
Step-by-step explanation:
Given the linear equation, y = 2x - 4, you could practically choose any input value (for x), to have an output value (for y).
If x = 0:
y = 2(0) - 4
y = 0 - 4
y = -4
First ordered pair: y-intercept = (0, -4)
If x = 1:
y = 2(1) - 4
y= 2 - 4
y = -2
Second ordered pair: (1, -2).
If x = 2:
y = 2(2) - 4
y= 4 - 4
y = 0
Third ordered pair: x-intercept = (2, 0).
If x = 3:
y = 2(3) - 4
y = 6 - 4
y = 2
Fourth ordered pair: (3, 2).
If x = 4:
y = 2(4) - 4
y = 8 - 4
y = 4
Fifth ordered pair: (4, 4).
Your input values (x) = {0, 1, 2, 3, 4}
Your output values (y) = {-4, -2, 0, 2, 4}

(i) [tex](a^{b})^{c} = a^{b\cdot c}[/tex]
(ii) [tex]a^{c}\cdot b^{c} = (a\cdot b)^{c}[/tex]
(iii) [tex]a^{-b} = \frac{1}{a^{b}}[/tex]
(iv) [tex]a^{b} = a^{b}[/tex], donde [tex]a[/tex] es negativo o positivo y [tex]b[/tex] es par.
(v) [tex](-a)^{b} = -a^{b}[/tex], donde [tex]a[/tex] es positivo y [tex]b[/tex] es impar.
(vi) [tex]a^{b}\cdot a^{c} = a^{b+c}[/tex]
A continuación, tenemos los siguientes resultados:
a) [tex](2^{3})^{7} = 8^{7} = 2097152[/tex]
b) [tex](3^{3})^{-2} = 3^{-6} = \frac{1}{729}[/tex]

h) [tex](2\cdot x^{5})^{3}\cdot (-5\cdot x^{2})^{2} = (2^{3}\cdot x^{15})\cdot [(-5)^{2}\cdot x^{4}] = (8\cdot x^{15})\cdot (25\cdot x^{4}) = (8\cdot 25)\cdot x^{19} = 200\cdot x^{19}[/tex]
i) [tex]\left(3\cdot y^{\frac{2}{3} }\right)^{3}\cdot (2\cdot y^{2})^{2} = (27\cdot y^{2})\cdot (4\cdot y^{4}) = 108\cdot y^{6}[/tex]

Please help ASAP BRAINLEST!!!
Answer:
-5/6a - 5/8
Step-by-step explanation:
In order to to simplify the linear expression you must combine like terms.
"like terms" are terms whose variables and exponents are the same. for example 2x and x are like terms. In this case, -2/3a and -1/6a are like terms as they have the same variable (a) and exponent (1). -2/3a - 1/6a = -4/6a - 1/6a = -5/6a
Next, we combine the constants 1/8 and -3/4. 1/8 - 3/4 is the same as 1/8 - 6/8 which is equal to -5/8. Therefore the final simplified linear expression is -5/6a -5/8.

A store sells a box of pencils for $3. Each box contains 24 pencils. How much will it cost a teacher to buy pencils
for 25 students?
$6
$9
$54
$150
Answer:
$6
Step-by-step explanation:
This is for one pencil to each student. Since each box is $3, and she has 25 students, you would figure out how many students are left out with one box, and since you only have one left, you only need one more box. That would mean two boxes, so $3x2= $6

Diseases tend to spread according to the exponential growth model…Help plz!! Will mark branliest! Show me the steps.
[tex]growth\:=(\frac{present \: value}{past \: value})^{ \frac{1}{n} } \: - 1 [/tex]
past value = 1700 people
n = 2005 - 1983 = 22
growth rate = 190%
present value = ?
then,
[tex]190\% = ( \frac{?}{1700})^{ \frac{1}{22} } - 1[/tex]
1.9 = (x/1700) ^(1/22) - 1
1.9 + 1 = (x/1700) ^(1/22)
2.9 = (x/1700) ^(1/22)
log 2.9 = 1/22(logx - log 1700)
log2.9 = 1/22logx - 1/22log1700
log2.9 + 1/22log1700 = 1/22logx
log(2.9 * 1/22(1700)) = 1/22logx
log 224 = 1/22logx
log(224 - 1/22(x)) = 1
log(224 - 1/22(x)) = log 10
224 - 1/22(x) = 10
(234) * 22 = x
x = 5148.
