Parallelogram:
just multiply 16 by 30.
The area is 480.
Semicircles:
Since there are 2 semicircles, they can be merged to one circle.
The area of a circle is πr²
The diameter is 28, so the radius is 14.
Substitute and solve.
π14²
π196 ≈ 615.8
Now add 615.8 with 480
Your answer is 1,095.8 units squared.

Steve is rolling a six-sided number cube. what is the probability of the cube landing on a six?

chubhunter [2.5K]

Answer:

1/6

Step-by-step explanation:

Space = {1,2,3,4,5,6}

n(S) = 6

A = Event of getting 6 = {6}

n(A) = 1

P(getting six) = n(a)/n(S) = 1/6

Find a4 for the arithmetic series with S4=-36 and a1=9

erastova [34]

ANSWER

The 4th term is -27

EXPLANATION

The sum of the first n-terms of an arithmetic sequence is

$S_n= \frac{n}{2} (2a_1+d(n-1))$

It was given that,

$S_4 = - 36$

$a_1 = 9$

$- 36= \frac{ 4}{2} (2 \times 9+d(4-1))$

$-36=2(18+3d)$

$-18=18+3d$

$-18 - 18 = 3d$

$3d = - 36$

$d = - 12$

The n-term is given by:

$a_n=a_1+ (n-1)d$

We substitute n=4 to get,

$a_4=9+ (4-1) \times -12$

$a_4=9+ 3\times -12$

$a_4=9 - 36$

$a_4= - 27$

Find the product of (x 5)(x − 5). X2 − 10x 25 x2 10x 25 x2 − 25 x2 25.

den301095 [7]

Product of two polynomials can be done by distribution of multiplication over addition. The product of $(x+5)(x-5) = x^2 - 25$

<h3>What is distributive property of multiplication over addition?</h3>

Suppose a, b and c are three numbers. Then we have:

$a(b + c) = a\times b + a\times c$

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

The product result of the given expression is obtained as:

$(x+5)(x-5) = x(x - 5) + 5(x - 5) \\\\(x+5)(x-5) = x^{1+1} - 5x + 5x - 25 = x^2 - 25$

Thus,

The product of $(x+5)(x-5) = x^2 - 25$
