How many lines of symmetry does a triangle have

1 answer:

8 0

That depends on the shape of the triangle.

A scalene triangle has no lines of symmetry.
An isosceles triangle has one line of symmetry.
An equilateral triangle has three lines of symmetry.

If my hunch is correct, Watson, there is no triangle
with two and only two lines of symmetry.

Which of the following polynomials is a binomial

Dima020 [189]

Hey there!

A binomial is a polynomial that contains two terms. Terms are separated from one another by mathematical symbols, such as +, –, and ×. A term can be a variable, a variable with a coefficient, a constant, or really any combination of coefficient, variable, and exponent that you can think of. For example...

(3x² – xy)

(x + 3)

(5x – 6y)

...are all binomials.

Hope this helped you out! :-)

Find f '(a).<br> f(x) = 4x2 − 4x + 3

Vinvika [58]

Use the power rule
d(x^n)/dx = n·x^(n-1)
to form the derivative.
f'(x) = 4·2x -4
f'(x) = 8x - 4

Now, substitute "a" for "x" to find f'(a):
f'(a) = 8a - 4

Jason went to the post office and bought both 41-cent stamps and 26-cent postcards and spent $10.28. The number of stamps was 4

Charra [1.4K]

<h3>Jason bought 20 stamps of $0.41 each and 8 postcards of $0.26 each.</h3>

<em><u>Solution:</u></em>

Let stamps be s and postcards be p

Given that,

The number of stamps was 4 more than twice the number of postcards

s = 4 + 2p -------- eqn 1

Jason bought both 41-cent stamps and 26-cent postcards and spent $10.28

41 cent = $ 0.41
