Here the given expression is
And the given value of x=5 . We need to find the value of y when x=5. And for that, we need to plug 5 for x .
So when x=5, y= 7.6
The exact value of cos 45 as per the special triangle would be
Cos 45 = 1/✔️2
Rationalizing the denominator gives
✔️2/2 = 0.707.
A = (1/2)(x)(y)
Let x = diagonal 1
Let y = diagonal 2
The product of xy = 144.
This means that x = 12 and y = 12.
So, 12 • 12 = 144
Each diagonal is 12 feet.
Prove:
72 feet = (1/2)(12)(12) feet
72 feet = (1/2)(144) feet
72 feet = 72 feet
Answer:
Facing Right
Step-by-step explanation:
Given inequalities are:
4-x≤-1
Subtracting 4 from both sides
4-x-4≤-1-4
-x≤-5
Multiplying both sides with -1. Multiplying with a negative number changes the sign of the inequality
So,
x≥5
Second Inequality:
2+3x≥17
Subtracting 2 from both sides
2+3x-2≥17-2
3x≥15
Dividing both sides by 3
x≥5
Union of both solutions:
x≥5 ∩ x≥5
=> x≥5
Hence the solution will be facing right on the number line towards all numbers greater than or equals to 5 ..
16 + 4x = 10 + 14
16 + 4x = 24.
4x = 24 - 16
4x = 8
x = 8 ÷ 4
x = 2
8x = 2 × 8
8x = 16
Final answer = 16.
