Step-by-step explanation:

Use the Pythagorean Theorem to find the missing sides in the triangles.

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

Q2. c^{2} = 8^2 + 40^2

c^{2} = 1664

c = \sqrt{1664}

c = 8\sqrt{26}

Find the missing sides of the other triangles and figure out which ones are the same.

Q3. Do the same thing as Q2.

How can u classfiy a quadulaterl​
irina [24]

Step-by-step explanation:

A quadrilateral is a closed figure with four sides and four vertices. The vertex is a point where line segments meet. The points where the sides of a quadrilateral meet are called the vertices (which is the plural form of "vertex"). The prefix “quad” means four. You can always remember that a quadrilateral is a four sided figure because of this prefix.

If f(x) =ax+b ,f(-3)=-4 and f(3)=2, find the value of a and b please help​
galina1969 [7]

Answer:

a = -⅓

b = 3

Step-by-step explanation:

-3a + b = 4

3a + b = 2

b = 4 + 3a = 2 - 3a

6a = -2

a = -2/6

a = - ⅓

-> b = 4 + 3(-⅓)

b = 4 - 1

b = 3

Consider the given function and the given interval.
docker41 [41]

Answer:

  (a)  fave = 8

  (b)  c = 64/9

  (c)   c ≈ 7.111

Step-by-step explanation:

(a) The average value of the function is its integral over the interval, divided by the width of the interval.

  f_{ave}=\displaystyle\frac{1}{16-0}\int_0^{16} {3x^{\frac{1}{2}}} \, dx=\left.\frac{x^{3/2}}{8}\right|_0^{16}=8

__

(b) We want ...

  f(c) = 8

  3√c = 8 . . . . . use f(c)

  √c = 8/3 . . . . . divide by 3

  c = (8/3)² . . . . square

  c = 64/9

__

(c) c ≈ 7.111

Write each as a fraction or mixed number in lowest terms<br> 6.05 <br> 12.346<br> 7.5
AVprozaik [17]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the decimal number

6.05

Rewrite as

=6+0.05

=6+\frac{5}{100}        ∵ 0.05 = 5/100

=6+\frac{1}{20}

=\:\frac{121}{20}

=6\frac{1}{20}

Given the decimal number

12.346

Rewrite as

=12+0.346

=12+\frac{173}{500}              ∵ 0.346 = 346/1000 = 173/500

=12\frac{173}{500}

Given the decimal number

7.5

Rewrite as

=7+0.5

=7+\frac{1}{2}                 ∵ 0.5 = 1/2

=7\frac{1}{2}
