Answer:
1.B 2.B 3.A
Step-by-step explanation:
1.(70-24)/2 = 23
2. 295 x 8.95 =2640.25 - 400 = 2240.25 ~ $2000
3. 21hoursx48 weeks x 2years = 2016 hours ~ 2000
Answer:
p^2 + q^2 = 22/9.
Step-by-step explanation:
For a quadratic function ax^2 + bx + c if the zeroes are A and B then
A + B = -b/a and AB = c/a.
2x^2 - 7x + 3
Now p and q are the zeroes of the above function so
p + q = 7/3 and pq = 3/2.
Now p^2 + q^2 = (p + q)^2 - 2pq
= (7/3)^2 - 2* 3/2
= 49/9 - 3
= 49/4 - 27/9
= 22/9.
1st :The angle of depression 30° = the angle of elevation (from the truck to the height of the building.
2nd :
cos 30° = (adjacent side)/(hypotenuse)
cos 30° = x/100, but cos 30°= (√3)/2
(√3)/2 = x/100 and x = (100√3)/2
and x = (50.√3) = 86.60 m
Answer:
3/8
Step-by-step explanation:
1 - 1/4 = 3/4
1/2 of 3/4 = 3/8
“A” is the answer i believe !
