what is the total surface area in square millimeters, of the rectangle solid shown below? HELP PLEASE!
Answers
Answer:
D) 290
Step-by-step explanation:
w = 5
l = 12
h = 5
Formula:
SA = 2(wl + hl + hw)
SA = 2(5*12 + 12*5 + 5*5)
SA = 2(60 + 60 + 25)
SA = 2(145)
SA = 290

Answers
Answer:
y = 3/2x - 1.5
Step-by-step explanation:
m = y² - y¹ / x² - x¹
= 9 - 6 / 7 - 5
= 3/2
(5,6)
y = mx + c
6 = 3/2 (5) + c
6 = 7.5 + c
6 - 7.5 = c
c = -1.5

The given factor (3x – 12)(x + 4) is not equivalent to the 3(x2 – 8x + 16) hence, correct option is (A).
What is an algebraic factor?An algebraic factor is the multiplication of two algebraic terms.
That term could be in form of summation multiplication or in subtraction.
The root of the quadratic equation formed by the algebraic factor is always real.
If we divide algebraic factor by a factor which is available inside then the remainder after the division will be zero.
Given that equation
(3x – 12)(x + 4)
⇒ 3x² + 12x - 12x - 48
⇒ 3x² - 48.
Now by option cross-checking
In option (A)
3(x² – 8x + 16)
⇒ 3x² - 24x + 48 which is not equal to the (3x – 12)(x + 4).
Hence correct option will be 3x² - 24x + 48.

Would you rather, $20 off your entire purchase or 20% off your entire purchase?
(I need at least 2 good reasons why, please help!) < 3
Answers
Answer:
i personally would much rather have $20 off, because as the price goes up the less money you get off of the total price. but with $20 off, youre automatically getting $20 off. if you were to get %20 off of something that is $50, youd only get about $10 off, but if you used the $20 off coupon, you would get $20. which would be much better. so instead of partially getting some of it off, you can get a much larger amount off

To investigate housing needs in the future, a town planning committee
created a model to help predict the growth of the population of the town. The
data are shown in the table.
Answers
Answer:
P(t) = 5.24(1.030)^t
Step-by-step explanation:
The model for P(t) , the population of the town, t years after 1985, best fits the data is option C. P(t) = 5.35 (1.029)^t.
What is Population Growth?Population growth is defined as the increase in the number of people which is calculated using population growth rate.
Population growth is an exponential function.
So, the function will be of the form,
P(t) = a (b)^t
Initial population is the population in 1985.
P(0) = a (b)⁰ = 5.35
⇒ a × 1 = 5.35 (Since any number raised to 0 is 1)
⇒ a = 5.35
Population in 1990, that is after 5 years is,
P(5) = a (b)⁵ = 6.01
⇒ 5.35 (b)⁵ = 6.01
⇒ (b)⁵ = 1.123
⇒ b = 1.024
So the function which best models is P(t) = 5.35 (1.029)^t.
Hence the function is C. P(t) = 5.35 (1.029)^t.
