Step-by-step explanation: Can someone please help me???
What is the solution to −2x+8≥4?
x≤2x is less than or equal to 2
x≥2x is greater than or equal to 2
x≤−6x is less than or equal to negative 6
x≥−6
"To solve this problem, the formula can be used
I = P / T
Where I is the fraction of the sample
P is the amount of the sample
T is the total amount of sample
Since P = 252 chicken sandwiches and I = 0.55
And solve for T
T = 252 / 0.52
T = 458 sandwiches in total"
hope this helps
Answer:
I'm pretty sure it's -3/2
Curved surface area of a sphere =1256 cm
2
We know that, Curved surface area of a spehre =4πr
2
⟹1256=4×3.14×r
2
⟹r
2
=
4×3.14
1256
⟹r
2
=100
∴r=10 cm
Hence, the answer is 10 cm.
4186.66666666 volume of sphere

<u>Explanation</u></h3>
The vertex of Parabola is the maximum/minimum point depending on the value of a.
<u>h-value</u>
<u>k-value</u>
The minimum value is the value of k. Therefore the minimum value is - 49/4 at x = -5/2.
This is Calculus method. We simply differentiate the function then substitute y' = 0.
Substitute f'(x) = 0
Substitute x = -5/2 in the original equation.
