Answer:
New altitude = 5.5 miles
Step-by-step explanation:
We are given;
Velocity = 400 m/h
Angle of descent = 1°
Altitude = 7.2 miles
Time = 15 minutes = 15/60 hours = 0.25 hours
Now, the downward component of its speed is;
Vy = (400)sin(1°)
Vy = 6.98 mph
After a time t, its height will be;
h(t) = (7.2 - 6.98t) miles, for t = hours
We are given;t = 0.25 hrs
Thus;
h(0.25) = 7.2 - (6.98*0.25) miles
h(0.25) = 5.46 miles
h(0.25) ≈ 5.5 miles to the nearest tenth
Answer: B
If you multiply equation 1 by -5 you get: -10x-y=3.
If you multiply equation 2 by 2 you get: 10x+4y=14
Add the systems together to eliminate x.
Do not simplify any part of the expression.
B. 4(2a + 5)
C. 4(4a + 16)
D. 4(4a + 5)
The expression 8a + 20 is equivalent to the expression 4(2a + 5). Then the correct option is B.
The equivalent is the expression that is in different forms but is equal to the same value.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The expression is given below.
⇒ 8a + 20
Factorize the terms of the expression, then we have
⇒ 4 × 2a + 4 × 5
Take 4 common from both terms, then we have
⇒ 4 × 2a + 4 × 5
⇒ 4 (2a + 5)
The expression 8a + 20 is equivalent to the expression 4(2a + 5). Then the correct option is B.
