Sharon is jumping from an 18-foot diving board with an initial upward velocity of 4 ft/sWhen Sharon jumps, Megan throws a beach
likoan [24]

Answer:

1.08 seconds

Step-by-step explanation:

given data

<u>first equation:</u>

According to the data, sharon position will be

h(t)= -16 t^{2} + 4t +18---->eq(1)  

<u>Second equation;</u>

When Sharon jumps, Megan throws a beach ball up to Sharon with an initial upward velocity of 16 ft/s from a height 5 feet off the ground to the nearest hundredth of a second

therefore, ball position would be

h(t)= -16t^{2} +16t +5 --->eq(2)

In order to find how long after she jumps does the ball reach Sharon i.e time, we will equate eq(1) and eq(2)

Therefore,

eq(1)= eq(2)

-16t^{2} +4t +18 = -16t^{2} + 16t +5  --->(further simplifying it)

-16t^{2} + 16t^{2} + 18 -5 = 16t - 4t

13 = 12t

t= 13/12

t= 1.08 s

Thus it took 1.08 seconds.

What is the factor of 6a2 – 19a + 10 ???
Dimas [21]

Answer:

(2a - 5) • (3a - 2)

step by step explanation:

Step-1 : Multiply the coefficient of the first term by the constant 6 • 10 = 60

Step-2 : Find two factors of 60 whose sum equals the coefficient of the middle term, which is -19 .

-60 + -1 = -61

-30 + -2 = -32

-20 + -3 = -23

-15 + -4 = -19 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -15 and -4

6a2 - 15a - 4a - 10

Step-4 : Add up the first 2 terms, pulling out like factors :

3a • (2a-5)

Add up the last 2 terms, pulling out common factors :

2 • (2a-5)

Step-5 : Add up the four terms of step 4 :

(3a-2) • (2a-5)

Which is the desired factorization

Final result :

(2a - 5) • (3a - 2)

Select the statements that are true for the graph of y=−(x−0.5)2+9 . Choose all correct statements. The vertex is (−0.5,9) . The
Lapatulllka [165]

Answer:

Second and last

Step-by-step explanation:

The vertex form of a quadratic function is written as: a(x-h)^2+k where (h,k) are the coordinates of the vertex

The equation y =-(x-0.5)^2+9

Then the vertex of this graph is (0.5,9)

◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇

The equation -(x-0.5)+9 has a negative leading factor so the parabola will open down then it will have a maximum
