Step-by-step explanation:
(3+-9)/2=-3
(1+-7)/2=-3
Answer : acute
Right triangle : a^2+b^2=c^2
Acute triangle : a^2+b^2 > c^2
Obtuse triangle:a^2+b^2 < c^2
6^2+7^2 > 9^2
T M - time that Maria drove;
49 * t C + 52 * t M = 191
t C + T M = 3.8 hours
t C = 3.8 - t M
49 * ( 3.8 - t M ) + 52 * t M = 191
186.2 - 49 t M + 52 t M = 191
3 t M = 191 - 186.2
3 t M = 4.8
t M = 4.8 : 3
t M = 1.6 hours
Answer:
Maria drove 1.6 hours.
125 - 78 = 47

Step-by-step explanation:
Find the complete question below;
Given the height modeled by the function;
h(t) = 5 + 98t-4.9t²
when t = 0
h(0) = 5 + 98(0)-4.9(0)²
h(0) = 5
when t = 5
h(5) = 5 + 98(5)-4.9(5)²
h(5) = 5 + 490 - 122.5
h(5) = 372.5
when t = 10
h(10) = 5 + 98(10)-4.9(10)²
h(10) = 5 + 980 - 490
h(10) = 495
when t = 15
h(15) = 5 + 98(15)-4.9(15)²
h(15) = 5 + 1470 - 1,102.5
h(15) = 372.5
when t = 20
h(10) = 5 + 98(20)-4.9(20)²
h(10) = 5 + 1960 - 4.9(400)
h(10) = 1965- 1960
h(10) = 5
