7 0

Answer:

Step-by-step explanation:

Hint:

a² - 9a + 15  = (a-7)(a-2)

a² + 9a + 15  = (a+7)(a+2)

a² + 3a - 10 = (a-2)(a+5)

a² + 5a - 14 = (a-2)(a+7)

a² - 5a - 14 = (a-7)(a+2)

A fireman is heading towards a forest fire and needs to know how far away the fire is. The person in the fire tower can determin
hjlf

Answer: 3.82 miles

Step-by-step explanation:

According to the shown figure, we can imagine the scene as a <u>right triangle</u>, where the tower is located at the right angle, and the fireman and the forest fire located at each of the other two vertices.

So, since we are dealing with a right triangle we can use the Pithagorean Theorem, in order to find the distance from the fireman to the fire d, which is also the hypotenuse.

d^{2}= (2.1 miles)^{2} +(3.2 miles)^{2}

d=\sqrt{(2.1 miles)^{2} +(3.2 miles)^{2}}

Finally:

d=3.82 miles

Someone answer this please, I’ll give you brainliest and your getting a lot of points.
ANTONII [103]

Answer:

Step-by-step explanation:

Recursive formula

tn = t_n-1 / 4

t2 = t1 / 4

t2 = 10240

t1 = 10240 / 4 = 2560

Explicit formula

tn = 10240 / 4^(n-1)

t4 = 10240 / 4^(4 - 1)

t4 = 10240 / 4^3

t4 = 10240 / 64

t4 = 160

t8 = 10240 / 4^7

t8 = 0,625
