Find the area of the triangle

Helga [31]

Answer:

The answer is

$\huge \boxed{54 \: \: {units}^{2} }$

Step-by-step explanation:

Area of a triangle is given by

$A = \frac{1}{2} \times base \times height \\$

From the question

base = 18

height = 6

So we have

$A = \frac{1}{2} \times 18 \times 6 \\ = 9 \times 6 \\ = 54 \: \: \: \: \:$

We have the final answer as

<h3>54 units²</h3>

Hope this helps you

Answer: $\sum_{n=1}^{5}4^n=1364$

Step-by-step explanation:

Since we have given that

$\sum_{n=1}^{5}4^n$

Now, we know the rule for summation , we'll apply this ,

$\sum_{n=1}^{5}4^n\\=4^1+4^2+4^3+4^4+4^5\\$

Now, it becomes geometric progression, so we us the formula for sum of terms in g.p. which is given by

$S_n=\frac{a(r^n-1)}{r-1}\\\\\text{where 'a' is the first term and 'r' is the common ratio}$

So, our equation becomes ,

$a=4 \\\\r=\frac{a_2}{a_1}=\frac{4^2}{4}=4\\\\S_5=\frac{4(4^5-1)}{4-1}\\\\S_5=1364$

Hence ,

$\sum_{n=1}^{5}4^n=1364$

A boutique prices merchandise by adding 80% to its cost. It later decreases by 25% the price of items that do not sell quickly

Darya [45]

A. Write a function f(x) to represent the price after the 80% markup.
<span>b. Write a function g(x) to represent the price after the 25% markdown. </span>
<span>c. Use a composition function to find the price of an item after both price adjustments that originally costs the boutique $150. </span>
<span>d. Does the order in which the adjustments are applied make a difference? Explain.
</span>
answers

<span>a) f(x) = 1.8x

b) f(x) = 0.75(1.8x)

c) f(150) = 0.75(1.8(150) = $202.50

d) No, it doesn't matter. The result is the same.
