What is the volume of the triangular prism A) 12 cm B) 18 C) 24 D) 48

lisov135 [29]

Remember the formula for calculating volume is: Volume = Area by height. V = A X h.
For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.
So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h

The exponential model A=429e 0.024t describes the population, A, of a country in millions, t years after 2003. Use the model t

d1i1m1o1n [39]

Answer:

Year 2,590

Step-by-step explanation:

In this question, we are asked to calculate the year at which the population of a country will be a certain amount given the exponential equation through which the equation proceeds.

Let’s rewrite the exponential function;

A = 429e^0.024t

Now here, our A is 559,000,000

t is unknown

Let’s substitute this value of A in the exponential equation;

559,000,000 = 429 * e^0.024t

559,000,000/429 = e^0.024t

1,303,030.303030303 = e^0.024t

Let’s take the logarithm of both sides to base e, we have;

ln(1,303,030.303030303) = ln(e^0.024t)

14.08 = 0.024t

t = 14.08/0.024

t = 587 years

Now, we add this to year 2003 and this gives year 2590

Help!Write the equation in slope- intercept form of the line that passes through (−1, 11) and is parallel to the graph of y = −8

love history [14]

Answer:

y = -8x + 3

Step-by-step explanation:

plug in the point and the slope into the slope intercept formula (y=mx+b)

the slope will be the same since you want the line to be parallel

11 = -8(-1) +b now solve for b

11 = 8 + b

-8 -8

3 = b

now write the equation with only the slope and the y intercept

y = -8x + 3

2x + 3y + x + 7 identidy the terms, like terms, coefficients, and constants in each expression

charle [14.2K]

Answer:

terms, 2x, 3y , x and 7,

like terms, 2x, 3y, x and 7

Coefficient. 2 is the coefficient of 2x and 3 is the coefficient of 2y 1 is the coefficient of x

Constant. 7

Step-by-step explanation:

Given:

$2x+3y+x+7$

Terms are the number of parts in the expression.

there are four terms 2x, 3y , x and 7,

Like terms are the part of the polynomials. 2x, 3y and x are like terms because they both have an x attached. 7 is like terms because they have nothing attached.

The number that are attached to variable is called Coefficient.

So In the term 2x the number 2 is a coefficient because it is attached to x similarly 3y the number 3 is a coefficient because it is attached to y

and in the term x the number 1 is a coefficient.

Constant are the numbers that are not attached to any variable and it is not change. Such as 7 is the constant term.
