If the length of the legs of a right triangle are 5 m and 7 m, what is the length of the hypotenuse?

irakobra [83]

Answer:

$c = 8.60232526704263$

$c \approx8.6$

Step-by-step explanation:

${c}^{2} = {a}^{2} + {b}^{2}$

$c = \sqrt{ {a}^{2} + {b}^{2} }$

$c = \sqrt{ {5}^{2} + {7}^{2} }$

$c = \sqrt{25 + 49}$

$c = \sqrt{74}$

$c = 8.60232526704263$

$c \approx8.6$

A circle is centered at the point (-7,-1) and passes through the point (8, 7). The radius of the circle is ___ units. The point

trapecia [35]

Answer:

(x + 7)2 + (y + 1)2 = r2.

To get we use point (8, 7): (8 + 7)2 + (7 + 1)2 = r2, r2 = 225 + 64 = 289 = 172.

So, equation of circle: (x + 7)2 + (y + 1)2 = 289

Elza [17]

Answer:

Step-by-step explanation:

Given that in a recent poll 1 of 1000 American adults, the number saying that exercise is an important part of daily life was 753.

Sample proportion = $\frac{753}{1000} =0.753$

To find 90% confidence interval we must find std error of proportion first

As per central limit theorem, sample proportion will follow a normal distribution with mean = 0.753

Std error of proportion= $\sqrt{0.753*0.247/1000} \\=0.01363$

90% Z critical value = 1.645

Margin of error = 1.645*0.01363 = 0.0224

Confidence interval lower bound = 0.753-0.0224=0.731

Upper bound = 0.775

Anon25 [30]

H1 (t) = 196 - 16 t-squared. / / / H2 (t) = 271-16t-squared. / / / In each function, 't' is the number of seconds after that ball is dropped. / / / Each function is only true until the first time that H=0, that is, until the first bounce. Each function becomes very complicated after that, and we would need more information in order to write it.
