In δabc, ∠c measures 46° and the values of a and c are 10 and 9, respectively. find the remaining measurements of the triangle, and round your answers to the nearest tenth.
∠a = 82.2°, ∠b = 62.8°, b = 17.1
∠a = 53.1°, ∠b = 80.9°, b = 12.4
∠a = 53.1°, ∠b = 80.9°, b = 17.1
∠a = 82.2°, ∠b = 62.8°, b = 12.4

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
