In a 45-45-90 triangle, what is the length of the hypotenuse when the length of one of the legs is 11 in.?

lana [24]

Answer:

= 15.556 in

Step-by-step explanation:

Since this is a 45-45-90 triangle, we can tell that;

This is a right triangle
This is an isosceles triangle

One of the theorems of geometry, the Isosceles Right Triangle Theorem, says that the hypotenuse is √2 times the length of a leg.

Therefore;

hypotenuse = leg × √2

If we take hypotenuse as x

Since the leg is 11;

Then; x = 11√2

x = 11/√2

x = 15.556 in

Miguel’s bank is offering savings accounts with 4% interest compounded continuously, If Miguel invests $500 how much will he hav

Triss [41]

Answer:

After 2 years Miguel will have in his account $541.64

Step-by-step explanation:

The formula for calculating compound interest continuously is:

$A=pe^{rt}$

Where A is the amount of money obtained after t years.

r is the compound interest rate and p is the initial amount

In this case we have that:

$p=\$500\\\\t=2\ years\\\\r=0.04$

Then we must find the final amount A

$A=500e^{0.04(2)}$

$A=\$541.64$

If the diagonal of the rectangle is 10.5 inches and the length of the rectangle is 7.25, what is the width of the rectangle?

Vlad [161]

Answer:

w≈7.6in

Step-by-step explanation:

L= 7.25

D= 10.5

Using the formula $d=\sqrt{w^{2} + l^{2} } \\$
Solving for w $w=\sqrt{d^{2} -l^{2} }$
$\sqrt{10.52^{2}-7.25^{2} } = 7.59523in$
