Solve x2 − 8x + 15 < 0.

1 answer:

n200080 [17]3 years ago

5 0

Answer:

Step-by-step explanation:

Given the quadratic inequality we are to find the interval of x

x² − 8x + 15 < 0

Factorize

x²-3x-5x+15<0

x(x-3)-5(x-3)<0

(x-3)(x-5)<0

(x-3)<0 and x-5<0

if x+3<0

x<-3

If x-5<0

x<5

Hence the solution yo the quadratic inequality are x<3 and x<5

Hence

Find the volume of the sphere.

Ksju [112]

Answer:

$\frac{1}{48} \pi$ units cubed

Step-by-step explanation:

The volume of a sphere is: $\frac{4}{3}\pi r^{3}$

We know the radius r = 1/4, so we just plug this into the equation:

(4/3)* $\pi$ *(1/4)^3 = (4/3)* $\pi$ *(1/64) = $\frac{1}{48} \pi$

So, the answer is $\frac{1}{48} \pi$ units cubed.

The distance a butterfly flies varies directly with it's time in the air. If a butterfly travels 264 ft in 0.5 min, how far will

Eva8 [605]

Answer:

The butterfly travels 660 ft in 1.25 min.

Step-by-step explanation:

If the distance, d, a butterfly flies varies directly as the time,t in the air, then we can write the mathematical statement.

$d\propto t$

If we introduce the constant of proportionality, we obtain;

$d=kt$

According to the question, when $d=264\:ft$ , $t=0.5\:min$ .

We substitute these values to obtain;

$264=0.5k$

$\Rightarrow k=\frac{264}{0.5}$

$\Rightarrow k=528$

The direct variation equation now becomes

$d=528t$

When $t=1.25\:min$

$d=528(1.25)$

$d=660$

Therefore the butterfly will travel 660 ft in 1.25 min.
