Answer:
1.93 x 10^-15
Step-by-step explanation:
You want to move the decimal just past the first real number and count the spaces moved, which is 15. Since the decimal is being moved to the right the spaces moved will be negative. Therefore you remove the zeroes and get 1.93 times 10 to the negative 15th power.
Answer:
Step-by-step explanation:
A car leave P and drives 3km North to Q. From Q it's drives 15km on a bearing North 45degree East to R. Find the distance and bearing of R from P
Answer:
(3,1) is the midpoint
Step-by-step explanation:
To find the x coordinate of the midpoint, average the x coordinates of the endpoints
(7+-1)/2 = 6/2 =3
To find the y coordinate of the midpoint, average the y coordinates of the endpoints
(10+-8)/2 = 2/2 = 1
(3,1) is the midpoint
If you need more steps, just ask!
Finding zeros or setting y ot f(n) equal to zero
and all you have to do is factor it, hoping you know how to do this
5. 0= n^2-2n-15
(n-5)(n+3)= 0
n-5= 0 n+3=0
n=5 and n=-3
6.t^2+6t=27
t^2+6t-27=0
(t + 9) (t-3)= 0
t=-9 and t=3
7. x^2-9x=-18
x^2-9x+18=0
(x-6)(x-3)= 0
x=6 and x=3
8. a^2 - 7a = 30
a^2 - 7a -30= 0
(a-10)(a+3)=0
a=10 and a=-3
hope that helps
