Which expression is equivalent to 64y18 – 1000z6?

natta225 [31]

Answer:

$(4y^{6})^{3}-(10z^{2})^{3}$

Step-by-step explanation:

we have

$64y^{18}-1000z^{6}$

we know that

$64=4^{3}$

$y^{18}=(y^{6})^{3}$

$1000=10^{3}$

$z^{6}=(z^{2})^{3}$

Substitute the values in the expression

$(4^{3})((y^{6})^{3})-(10^{3})((z^{2})^{3})$

$(4y^{6})^{3}-(10z^{2})^{3}$

On a hot summer day in the state of Washington while kayaking, I saw several swimmers jump from a railroad bridge into the Snoho

tamaranim1 [39]

Answer: the bridge is 11.025 m high

Step-by-step explanation:

Given that;

Time taken to hit the water t = 1.5 sec

height of bridge = ?

lets take a look at the equation of motion;

y(t) = y₀ + (1/2)at²

with initial velocity zero and we know that acceleration due to gravidity is 9.8m/s

we substitute

y(t) = (1/2)gt² = (1/2) × 9.8 × (1.5)²

y(1.5) = 11.025 m

Therefore, the bridge is 11.025 m high
