Answer:
50.24m²
Step-by-step explanation:
area of circle
= 3.14 × r²
= 3.14 × 4 × 4
= 50.24
Answer:
After 1 second, the ball will reach a maximum height of 16 feet
Step-by-step explanation:
The height of the ball after t seconds: h(t) = -16t^2 + 32t
The graph of this quadratic function is parabola which opens downwards. The vertex of a quadratic equation is the maximum or minimum point on the equation's parabola
t = -b/2a = -(32)/2(-16) = -32/-32 = 1 second
then
h(t) = -16(1)^2 + 32(1) = -16 + 32 = 16
After 1 second, the ball will reach a maximum height of 16 feet
Answer Point R = 7/10
and Point
T = 9/10
7/10 · 9/10 = 63
63/100
6
/10 = point Q.
Step-by-step explanation:
Answer:
There is an error in the application of the DMAS rule, The answer as per the DMAS rule is 75.
Step-by-step explanation:
There is an error in the implication of the DMAS rule of Mathematics.
DMAS rule determines the arrangement of mathematical functions to be performed in an expression where multiple functions are present.
The DMAS Rules describes the following arrangement of the mathematical functions.
1st Division
2nd Multiplication
3rd Addition
4th Subtraction
Applying the above rule the solution is as follow
62 + 3 + 5 x 2
First, we need to solve the Multiplication because there is no division
62 + 3 + 10
Now perform the addition function
65 + 10
75
1 2/5 + 3 1/2
= 7/5 + 7/2
= ((7x2)+(7x5))/(5x2)
=(14+35)/10
=49/10
=4 9/10
