Answer for (3.1 - 1.15)²/0.005 is 760.5
Step-by-step explanation:
- Step 1: Given expression is (3.1 - 1.15)²/0.005
- Step 2: Simplify the expression using algebraic equation
(a - b)² = a² - 2ab + b². Here a = 3.1 and b= 1.15
⇒ (a - b)² = (3.1)² - 2×3.1×1.15 + (1.15)²
= 9.61 - 7.13 + 1.3225
= 10.9325 - 7.13 = 3.8025
- Step 3: Find the solution to the expression
⇒ (3.1 - 1.15)²/0.005 = 3.8025/0.005 = 760.5
Answer:
area ≈ 59.6 units²
Step-by-step explanation:
Calculate the area (A) of the triangle using
A = ac sinB
That is one half the product of the 2 sides and the sine of the included angle, thus
A = × 11 × 11 × sin100° ≈ 59.6 units² ( to the nearest tenth )
The numbers are (-8, 3) or (3, -8).
Step-by-step explanation:
- Step 1: Given the product of the numbers are -24 and their sum are -5. Let the numbers be a and b. Form equations out of these details.
⇒ a + b = -5 ⇒ b = -5 - a
⇒ a × b = -24 -------- (1)
- Step 2: Substitute the value of b in eq(1)
⇒ a × (-5 - a) = - 24
⇒ -5a - a² = -24
⇒ a² + 5a - 24 = 0
- Step 3: Solve the quadratic equation for a.
a = (-5 ± √25 - 4 × 1 × -24)/2
= (-5 ± √121)/2
= - 16/2, 6/2 = -8 or 3
- Step 4: For each value of a, find b.
When a = -8, b = -5 +8 = 3
When a = 3, b = -5 - 3 = -8.
Because:
(-2)+(-6)+(-4) = -12, then divide -12 by 3, which equals -4
