that’s the answers for them :), have a great day !! :)
Answer:
Step-by-step explanation:
The graph that represents the function
f(x) = (x + 4)(x + 1)(x - 3)
crosses the x-axis three times: at x = -4, x = -1, and x = 3
because we apply the zero product rule and found the roots -4, -1, and 3
x+ 4= 0 → x = -4
x+1 = 0 → x = -1
x-3 = 0 → x = 3
Answer:45
Step-by-step explanation:
First, you need to calculate the area of the square.
(LxW)= 25.
Then, calculate the area of the triangle
(1/2BH)=5x(8/2)=5x4=20
Now, just add 20+25= 45
Please mark me brainliest :)
The answer is C because it's two negatives. Hope that helped
Answer:
Step-by-step explanation:
height(h) mid value frequency
in cm x f xf
120<t≤124 122 7 854
124<t≤128 126 8 1008
128<t≤132 130 13 1690
132<t≤136 134 9 1206
136<t≤140 138 3 414
total 40 5172
mean height=5172÷40=129.30
mean height=129.30 cm
b.
it is an estimate i have taken only mid value,for example in the interval all the 7 students may be of length greater than 122 and viceverse.
Similarly for other intervals.
