Josh can long-jump 195% of his height with a running start. If Josh is 66 inches tall, how far can he long-jump?
Nikolay [14]

Answer: 128.7 inches

Step-by-step explanation:

Josh's height is 66 inches.

When he jumps with a running start, he can jump as far as 195% of his height.

The length he can jump is therefore 195% multiplied by his height:

= Josh height * 195%

= 66 * 195/100

= 128.7 inches

if (2x minus 1) is exactly divisible by 6 X square + ax - 4 and b x square - 11x + 3, then the value of b square minus a square
alexdok [17]

Step-by-step explanation:

Given that:-

(2x - 1)

is exactly divisible by

6 {x}^{2}  + ax - 4

and

b {x}^{2}  - 11x + 3

We need to simply, place the value of x.

2x - 1 = 0

2x = 1

x =  \frac{1}{2}

Now,

6 {( \frac{1}{2} )}^{2}  +  \frac{a}{2}  - 4 = 0

\frac{3  + a}{2}  = 4

3 + a = 4 \times 2 = 8

a = 8 - 3

a = 5

Now, to find b.

b {( \frac{1}{2}) }^{2}  - \frac{11}{2}  + 3 = 0

\frac{b}{4}  -  \frac{11}{2}  =  - 3

\frac{b - 22}{4}  =  - 3

b - 22 =  - 12

b = 10

is the answer.

Now, we need

{b}^{2}  -  {a}^{2} + a - b

100 - 25  + 100 + 5

= 205 - 25

= 180

is the answer.

Hope it helps :D
