The square root of 64(which is 8)is a rational number as it can be written as a fraction.

The square root of 64 is 16, which yes, is a rational number. You get the square root of 64, (or really, any number!) by dividing it by 4. your answer, which in this case, was 16, is a rational number because:
*it can be written as a ratio, like; 1:16
*it can be written as a fraction; 16/1 (be careful not to say it's reciprical, 1/16!!!)
*and finally, you can write this ration in word format, which will always be said as, 1 to 16, so you basically write "to" instead of (:)

What is the height and base of the triangle based off what the picture is giving me ? Pls help )):

scZoUnD [109]

The formula of triangle: height x base ÷2
here's how you can find x

x(2x+7)/2=92
2x^2+7x=92×2
2x^2+7x-184=0
x=8 or x=-11.5(rejected)

thus,the height would be 8

and the base would be: 2(8)+7=23

hope it helps!

FIND THE VALUE OF X AND Y.(ordered pairs)<br><br>(x+y,0)=(8,x-y)

Aliun [14]

Step-by-step explanation:

We know that...

x+y (from the first pair) corresponds to 8(in the second pair)..

0 (from the first pair) corresponds to x-y (in the second pair)..

Hence,

$x + y = 8 \\ x - y = 0$

By simply adding the two equations we get,

$2x = 8 \\ x = 4$

Hence,

By substituting x=4, we get that y=4

Hence,

x=y=4

The height of water shooting from a fountain is modeled by the function f(x) = −0.2x2 − 2.8x − 5.4 where x is the distance from

balandron [24]

Start by setting the function equal to 0 and then moving the -5.4 over to the other side of the equals sign. $-.2 x^{2} -2.8x=5.4$ . The first rule for completing the square is that the leading coefficient be a +1. Ours is a -.2. So we need to factor it out. $-.2( x^{2} +14x)=5.4$ . Now we will take half the linear term, square it, and add it to both sides. Our linear term is 14. Half of 14 is 7, and 7 squared is 49. So we add 49 in to the left side just fine, but we cannot forget about that -.2 hanging around out front as a multiplier. What we have actually "added" in is -.2*49 which is -9.8. Now here's what we have after all that: $-.2( x^{2} +14x+49)=5.4-9.8$ . In that process, we have created a perfect square binomial on the left. Along with expressing that binomial we will do the math on the right: $-.2(x+7) ^{2} =-4.4$ . Now we will move the -4.4 back over by addition, and it will then be apparent as to what our vertex is. The y coordinate of the vertex will give us the max height of the water. $-.2(x+7) +4.4=y$ . As you can see, our work matches choice C from above.
