Answer:
288
Step-by-step explanation:
If 52% studied French, then 48% didn't. The ratio of those who didn't to those who did is ...
(didn't study French)/312 = 48%/52% = 12/13
Then the number that didn't study French is ...
(didn't study French) = 312 × 12/13 = 288 . . . . . . multiply above by 312
288 students chose not to take French their Junior year.
Answer:
Step-by-step explanation:
A= P(1+r/100)^n
= 15000(1+1.5)^10
= 17408.11 [Ans]
Answer:
60 miles per hour
Step-by-step explanation:
You divide 300 by 5 and you get 60. You always need to divide the upper part to the lower part to reach the distance in ONE UNIT OF TIME. There, you have 5 seconds, yet you need the distance in 1 second.
This all is assuming that the train moved at a constant speed, where
ACCELERATION = 0, which is pretty improbable for a train.
Answer:
D) y=2/9x2+2x+4
Step-by-step explanation:
y-intercept=4
2 x intercepts= 3 and 6
so y-intercept is point where x is 0 like (0,y)
x-intercept is the opposite y is 0 (x,0)
that means y-intercept is (0,4)
x-intercept is (3,0) and (6,0)
the formula of slope intercept form is
y=mx+b
b= is y-intercept
that means
y=ox^2+mx+4
x-intercept is point where y is 0
so solve
now lets try the first option
This is are quadratic functions
you need to plug in both of these until u get one that is right
change the y until you get both x's
the first option if wrong
second one y = 6x2 + 3x +4 has no x-intercepts
3rd option y=3/4x^2-6x-4
last option is y=
2/
9
x2+2 has points at -6. and -2.9999 or -3
I can’t view the picture but good luck
