Within the set of whole numbers , one set of numbers satisfies the recursive formula an=(an-1)^2-an-1, when a4=870 what are the

andrew11 [14]

Answer: 3 and 6 will be the first and second term of the given series respectively.

Explanation: since it is given- $a_n=(a_{n-1} )^2-a_{n-1}$ and $a_4=870$

so, by replacing n by 4, we will get- $a_4=a_3^2-a_3$ ⇒870= $a_3^2-a_3$ ⇒ $a_3^2-a_3-870=0$

after solving this equation we will get, $a_3= -29$ and 30.

If $a_3= -29$ , but it is not a whole number.

Thus, $a_3=30$ will be the value of third term of the given series.

Again, by applying the given condition $a_n=(a_{n-1} )^2-a_{n-1}$ , $a_2= 6$ or -5 (not possible), so, $a_2=6$ will be the second term.

Similarly, $a_1=3$ or -2 but we will go to the whole number.

Thus, $a_1=3$ will be the first term.

Solve the equation or formula for the variable specified 8qr+4t=7u for q ?

g100num [7]

Answer:

q= −4t+7u over 8r

Step-by-step explanation:

8qr+4t=7u

Step 1: Add -4t to both sides.

8qr+4t+−4t=7u+−4t

8qr=−4t+7u

Step 2: Divide both sides by 8r.

8qr

−4t+7u

Answer:

−4t+7u

Write an equation that could be used to find the measure of angle A

Ainat [17]

Answer: C

Step-by-step explanation: The numerator is the angle measure, and the denominator is the side length. For angle B, the angle is 47 degrees. The opposite side is b, which is 85. We are finding the angle A, which is the numerator. The side 94 is opposite of angle A.
