Pythagorean theorem is $a^2+b^2=c^2$ , where a and b are the lengths, and c is the hypotenuse. We plug in 102 and 136 in our equation.
$102^2+136^2=c^2$ 102^2+136^2=28900. The square root of 28900 is 170.
170 is the answer

Answer:

x = 170

Step-by-step explanation:

Formula: a² + b² = c²

a = side of right triangle (known as the leg)

b = side of right triangle (also known as the leg)

c = hypotenuse

So we will find the C (x).

a² + b² = c²

136² + 102² = c² (evaluate both 136 and 102.)

18,496 + 10,404 = c² (Add)

28,900 = c²

Now all we need to do is find the square root of 28,900.

√28,900 = √C²

170 · 170 = 28,900

So:

170 = C

x = 170

Let f be the function that determines the area of a circle (in square cm) given the radius of the circle in cm, r. That is, f(r)

yarga [219]

Answer:

The answers to each question are:

a) $A=f(r=4cm)=50.26cm^2$

b) $\Delta A(10.91cm-10.9cm)=f(10.91cm)-f(10.9cm)=0.6851cm^2$

c) $C=5\cdot f(r=12.7cm)=2533.54cm^2$

d) $D=f(r=28cm)+59cm^2=2522.01cm^2$

Step-by-step explanation:

The function f(r) that represents the area of a circle (in square cm) is:

$f(r)=\pi r^2$

a) To represent the area (in square cm) of a circle whose radius is 4 cm, you just have to evaluate the function with a radius of 4cm:

$A=f(r=4cm)=50.26cm^2$

b) To represent how much the area (in square cm) of a circle increases by when its radius increases from 10.9 to 10.91 cm, you have to represent the difference between the final area with a radius of 10.91cm and the initial area of a radius of 10.9cm:

$\Delta A(10.91cm-10.9cm)=f(10.91cm)-f(10.9cm)=0.6851cm^2$

c) To represent the area of 5 circles that all have a radius of 12.7 cm, we can use the function f(r) to represent the area of a circle with a radius of 12.7cm and multiply it for 5:

$C=5\cdot f(r=12.7cm)=2533.54cm^2$

d) To represent the area of the larger circle that is 59 square cm more than the first circle (with a radius of 28 cm), we can use the function f(r) to obtain the area of the first circle and addition 59 square cm:

$D=f(r=28cm)+59cm^2=2522.01cm^2$

Ax+ by = c <br><br> solve for y

Luden [163]

Answer:

$\boxed{y=\frac{c}{b}-\frac{ax}{b}}$

Step-by-step explanation:

$ax+by=c\\\\ax-ax+by=c-ax\\\\by=c-ax\\\\\frac{by=c-ax}{b}\\\\\boxed{y=\frac{c}{b}-\frac{ax}{b}}$

Hope this helps.

Betty Donahue is choosing between two fitness centers. Center A charges $375 per year for unlimited use of all facilities. Cente

Ronch [10]

Center A : 375 per yr

Center B : 35 + 12(12) + 5(52) = 35 + 144 + 260 = 439 per yr
I multiplied 12 * 12 because it was $ 12 a month and there are 12 months in a yr. I multiplied 5 * 52 because each aerobic class is $ 5 per class, and she went once per week, and there are 52 weeks in a yr.

so the cheaper one is Center A
