Write the first five terms of the sequence defined by the explicit formula

denis-greek [22]

<u>Answer:</u>

The correct answer option is: 19, 13, 3, -11, -29.

<u>Step-by-step explanation:</u>

We are given the following explicit formula for an arithmetic sequence:

$a_n=21-2n^2$

So to find the first five terms of this sequence, we will substitute the values of $n$ (num here in the given formula:

$a_1=21-2(1)^2\\\\a_1=19$

$a_2=21-2(2)^2\\\\a_2=13$

$a_3=21-2(3)^2\\\\a_3=3$

$a_4=21-2(4)^2\\\\a_4=-11$

$a_5=21-2(5)^2\\\\a_5=-29$

Therefore, the first five terms of the sequence defined by the explicit formula $a_n=21-2n^2$ are 19, 13, 3, -11, -29.

What is the area of the trapezoid

Xelga [282]

Short answer: B
Remark
A 45 degree angle means that the height is the same length as part of the base. But which part?

Givens
b1 = 9 feet
b2 = 23 feet
and the 45 degree angle on the right.

Determine the height.
The part of the base that is associated with the 45 degree angle is found by subtracting b1 from b2
b2 - b1 = 23 - 9 = 14
So 14 is also the height

Find the Area
A = 1/2 (b1 + b2)*h
b1 = 9
b2 = 23
h = 14

Area = 1/2(9 + 23) * 14
Area = 1/2 (32) * 14
Area = 16 * 14
Area = 224 <<<< answer

HELP I NEED THIS DONE QUICKK CAN ANNYONE HELP???????????????????????????????????????????????????????????????????????????????????

natulia [17]

For the first question, it would be D: $\frac{1}{3}$ ÷ 9. This is because to solve a division problem with fractions, you would need to multiply the first fraction by the reciprocal of the second fraction. For the second question, the answer would be D: 32. This can be solved by dividing 8 by $\frac{1}{4}$ or 0.25. For the third question, it would be D. $\frac{1}{12}$ . This can be solved by dividing $\frac{1}{4}$ by 3. For the fourth question, the answer would be $\frac{1}{12}$ . This can be found by flipping the 4, which would make it look like $\frac{1}{4}$ , and multiplying it by $\frac{1}{3}$ . For the last question, 1 would be B, 2 would be C, 3 would be C, and 4 would be A.

Hope this helps ^-^
