Answer:
سأعطي فقط مثالاً مقدمًا أدناه آمل أن يساعد
Step-by-step explanation:
الارتفاع = 24 سم
نصف القطر = 14 ÷ 2 = 7 سم
ارتفاع مائل = L =؟
L2 = R2 + H2
م 2 = 72 +242
م 2 = 49 + 576
م 2 = 625
L = 25
الحجم = 1 ÷ 3 × 22 ÷ 7 × 7 × 24
الحجم = 1232 سم
مساحة السطح المنحني = 22 × 7 × 7 × 25
مساحة السطح المنحني = 550
إجمالي مساحة السطح = 22 × 7 × 7 × 25 + 7
مساحة السطح الكلية = 704 سم

I believe just the one, (−1,2)
Step-by-step explanation:
Answer:
k pi for k = 0, plus-or-minus 2, plus-or-minus 4, ellipsis
Step-by-step explanation:
The cosine is a maximum when its argument is at multiples of 2π.
k pi for k = 0, plus-or-minus 2, plus-or-minus 4, ellipsis

Both of us could probably read this more easily if you would use appropriate math symbols.
4x^2 -28x + 49=0
- move -49 to the other side
x^2-7x+49/4=0
- take out the 4 because you cannot complete the square with a coefficient in front of x^2
(x^2-7x +(7/2)^2) + 49/4 - (7/2)^2 = 0
- complete the square
4((x-7/2)^2)= 0
- bring the 4 back and you’re done.
hope this helped :)
Answer:
- Width = x
- Length = 26 + 4x
<u>Perimeter</u>
<u />
<u>Therefore, the dimensions are</u>
- Width = x = 15
- Length = 26 + 4x = 26 + 4(15) = 86
