Does every acute triangle have 3 congruent sides?
Gemiola [76]
No. Just because the angles are all less than 90 degrees, that doesn't tell us anything about the sides. The sides are all congruent ONLY if all 3 angles are 60 degrees each. If the angles all have different sizes, then so do the sides.

write a quadratic function that has a graph that contains the following points, (-2, 0), (4, -12), (5,0).
ankoles [38]

Answer:

f(x) =  2x^2 - 6x - 20.

Step-by-step explanation:

(-2, 0) and (5, 0)  are 2 zeroes of the function so we can write the function as

f(x) =  a(x + 2)(x - 5)   where a is a constant.

Now as (4, -12) is a point on the graph:

-12 = a(4 + 2)(4 - 5)

-12 = a * 6 * -1

-6a = -12

a = 2.

So f(x) = 2(x + 2)(x - 5)

f(x) =  2x^2 - 6x - 20.

A surfboard has a price of $920. With sales tax, it will cost $1,012. What is the sales tax percentage?
Solnce55 [7]

Answer: 10%

Step-by-step explanation:

Let the sale tax                                                    = $x

Cost price  (CP) of the surfboard                       = $920

Sale tax with cost price of the surfboard          = $1,012

Therefore the sale tax   ($x)                                     = $1,012 - $920

                                                                             =$92

Therefore the sale  tax percentage                   = ⁹²/₉₂₀  x 100

                                                                             = 10%
