Answer:

AC = 5.4 cm

Step-by-step explanation:

The area (A) of a triangle is calculated using the formula

A = \frac{1}{2} bh ( b is the base and h the perpendicular height )

here AC is the base (b) and AB the height (h), thus

\frac{1}{2} × AC × 6 = 16.2

3AC = 16.2 ( divide both sides by 3 )

AC = 5.4 cm

okay so you should know that the formula for a triangle is:

A=1/2×b×h

where b is breadth and h is height

A is area

so they already gave the area which is 16.2 and they already gave a side ( doesn't matter if it's b or h in this question)

so we put these into the equation of the area of a triangle

A=1/2×b×h

16.2=1/2 × 6 × h

then you will solve algebraically to get 5.4cm which is you answer

to check if correct you can always put in all numbers in equation and you should get 16.2cm

In this case it's correct ✌

F(x)=a^x which of the following expressions is equal to f(3) * f(4)<br> f(3^4)<br> f(3+4)<br> F(3*4)
Romashka-Z-Leto [24]

Answer:

option 2

f(3+4)

Step-by-step explanation:

To understand this problem, what we can do is solve and compare with the results they give us.

f(x)=a^x           f(3) * f(4)

f(3) = a^(3)      f(4) = a^(4)

we replace

f(3) * f(4) = a^3 * a^4

as they are powers of the same base

f(3) * f(4) = a^(3+4)

f(3) * f(4) = a^7

Now let's do it with the options they give us

1.   f(3^4)      f(x)=a^x

3^4 = 81     x = 81

f(81) = a^81    wrong option

2.   f(3+4)      f(x)=a^x

3+4 = 7     x = 7

f(7) = a^7       correct option

3.   f(3*4)      f(x)=a^x

3*4 = 12     x = 12

f(12) = a^12      wrong option

A company paid $48 for 2 cases of printer paper. Each case contained 12 packages of paper. Next month the company’s office manag
Studentka2010 [4]

Answer:

$360.

Step-by-step explanation:

First we need to find how much it costs for a single case of printer paper.

48 ÷ 2 = 24

It costs $24 to buy one case of 12 packages.

Now we have to figure out how many cases we will need to buy for the total amount of 180 packages.

I will divide 12 from 180.

180/12 = 15.

You will need to buy 15 cases to get 180 packages.

Now to find the cost, we have to multiply.

x = 15 (amount of cases)

y = $24 (price of case)

z = How much it costs.

x * y=z

Substitute:

15*24=z

Multiply:

15 * 24= 360

z=360

If the price does not change, the total cost of next month's order will be $360.

If p(x) = x²+x+6 and q (x)=3x-1 find q ( 1/4)
erma4kov [3.2K]
<h3>Answer is    -1/4</h3>

Work Shown:

q(x) = 3x - 1

q(1/4) = 3(1/4) - 1 ... replace x with 1/4

q(1/4) = 3/4 - 1

q(1/4) = 3/4 - 4/4 ... rewrite 1 as 4/4

q(1/4) = (3-4)/4

q(1/4) = -1/4

The p(x) function is never used.
