Answer:
Step-by-step explanation:
To find the total surface area of the cylinder
We get
S.A=2πr^2+2πrh
S.A=2×3.142×4×4+2×3.142×4×10
S. A=100.544inches sq+251.36inches sq
S. A=351.904inches sq
Answer:
D. <em>a</em> = 11.71 and <em>b</em> = 15.56
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Trigonometry</u>
- All angles in a triangle add up to 180°
<u>Pre-Calculus</u>
- Law of Sines:

Step-by-step explanation:
<u>Step 1: Define</u>
AC = b
CB = a
AB = 7
m∠A = 45°
m∠B = 110°
m∠C = ?
<u>Step 2: Find missing ∠</u>
- Set up equation: m∠C + 45° + 110° = 180°
- Combine like terms: m∠C + 115° = 180°
- Isolate unknown: m∠C = 25°
<u>Step 3: Find measure of </u><em><u>b</u></em>
- Substitute:

- Cross-multiply:

- Isolate <em>b</em>:

- Evaluate:

- Round:

<u>Step 4: Find measure of </u><em><u>a</u></em>

Answer:
-12°F
Step-by-step explanation:
2 P.M
-35° F + 29° F= -6° F
The temperature had risen by 29°F meaning it went up by 29.
Adding negative 35 and positive 29 is the same as subtracting 35 from 29.
29 - 35 = -6
6 P.M
-6° F - 18°F = -12°F
The temperature had fallen by 18°F meaning it went down by 18°F.
p.s don't forget the label °F
Answer:
x=3 and x=-5
Step-by-step explanation:
To find the x intercepts set y =0 and solve for x
0 = x^2+2x-15
Factor
What two numbers multiply to -15 and add to 2
5*-3 = -15
5+-3 =2
0 = (x+5) (x-3)
Using the zero product property
x+5=0 x-3 =0
x=-5 x=3
