76.3 rounded to the nearest whole number is 76
Answer:
a, b, and c can be formed a triangle
The area of the triangle is 13385.87 square units.
Step-by-step explanation:
<em>Let us revise an important fact in any triangle</em>
- The sum of the lengths of the two shortest side must be greater than the length of the longest side
The length of the sides are a = 240, b = 132, and c = 330
∵ The two shortest sides are a = 240 and b = 132
∵ a + b = 240 + 132 = 372
∵ The longest side is c = 330
∵ 372 > 330
∴ a + b > c
∴ a, b, and c can be formed a triangle
<em>Let us revise the </em><em>Heron's formula</em><em> of the area of the triangle</em>
- Area = , where a, b,c are the lengths of the sides of the triangle, and
∵
∴
∴
∴
The area of the triangle is 13385.87 square units.
Answer:
$190,000
Step-by-step explanation:
discount = x
original price = $200,000
discount% = 5%
x/200,000 = 5/100
x · 100 = 5 · 200,000
100x = 1,000,000
100x/100 = 1,000,000/100
x = 10,000
Sale price: $200,000 - $10,000 = $190,000
A reflection in the x-axis means the y-coordinate will be negated (the opposite sign). This means that g(x)=-f(x)=-(x^2+5=-x^2-5.
