1 answer:

8 0

By using the formula for arithmetic sequence, the 16th term of the progression can be obtained. Given A1=8 and d=3,
A16=A1+(n-1)d
A16=8+(16-1)(3)
A16=53

What are the solution(s) for the quadratic equation?

MariettaO [177]

Let's see

$\\ \rm\rightarrowtail x^2+12x+36=0$

$\\ \rm\rightarrowtail x^2+6x+6x+36=0$

$\\ \rm\rightarrowtail x(x+6)+6(x+6)=0$

$\\ \rm\rightarrowtail (x+6)(x+6)=0$

$\\ \rm\rightarrowtail x=-6$

There are 60 feet between the bases on a softball diamond. How far does a catcher throw drone home plate to second base

mixas84 [53]

Answer: $12\sqrt{5}$

Required theorem:

Pythagorean theorem = $a^2 + b^2=c^2$

In other words, one side length squared + another side length squared = the middle lined squared.

Step-by-step explanation:

$60^2+60^2 = c^2\\\\360+360=c^2\\\\720=c^2\\\\\ \sqrt{c^2} =\sqrt{720}\\\\c=+/- 12\sqrt{5}$

We can only have a positive distance so your final answer is :

$12\sqrt{5}$

Find two consecutive whole numbers that 90 lies between

lyudmila [28]

Let
a--------> the first whole number
a+1-----> the second consecutive whole number

we know that
if 90 lies between
then
[a+(a+1)]/2=90-------> 2a+1=180----> a=179/2-------> a=89.5
a=89.5
a+1=90.5
but
89.5 and 90.5 are not whole numbers

therefore
No solutions exist

the answer is
No solutions exist
