Step-by-step explanation:
D = b² - 4ac
#1D = 10² - 4 · 3 · 2
D = 100 - 24
D = 76
#2D = (-5)² - 4 · 1 · (-4)
D = 25 - (-16)
D = 26 + 16
D = 42
#3D = 7² - 4 · 1 · (-8)
D = 49 - (-32)
D = 49 + 32
D = 81
#4D = 0² - 4 · 1 · (-9)
D = 0 - (-36)
D = 36
#5D = (-6)² - 4 · 5 · 10
D = 36 - 200
D = - 164

410 = 1080(0.915)^x
Answer:
410/1080=(0.915)^x
0.379=(0.915)^x
ln0. 379/ln0.915=x
X=10.903
How do I solve this arithmetic sequence?
Answer:
The 16ᵗʰ term of this sequence is 82
Step-by-step explanation:
Here,
First Term = a₁ = 9
Common Difference = (d) = 2
Now, For 16ᵗʰ term, n = 16
aₙ = a + (n - 1)d
a₁₆ = 7 + (16 - 1) × 2
a₁₆ = 7 + 15 × 5
a₁₆ = 7 + 75
a₁₆ = 82
Thus, The 16ᵗʰ term of this sequence is 82

The 25th term of the given arithmetic sequence is -19.
The given arithmetic sequence is 53, 50, 47, 44, 41.
What is an arithmetic sequence?An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same. The general form an arithmetic sequence is an=a+(n-1)d
Here the first term of the sequence is a=53 and the common difference is
50-53=-3
Put, a=53, d=-3 and n=25 in the general form an arithmetic sequence, we get
a25=53+(25-1)×(-3)
= 53+24×(-3)
= 53-72
= -19
Therefore, the 25th term of the given arithmetic sequence is -19.

What is the surface area?
Someone please help
Answer:
134 square inches
Step-by-step explanation:
To find surface area, you must find the individual area of each face of the shape. There are 6 faces on every cube or other rectangular prism, so you must perform 3 equations, as every face has an identical face on the opposite side. The formula for regular area is Length (l) times Width (w).
Large sides on front and back: 8x6=48
Slim sides to the right and left: 1x6=6
Slim sides on top and bottom: 8x1=8
Then combine:
48+48+6+6+8+8=134

What is the graph of one cycle of a sine curve with amplitude 5, period pi, and a>0?
What is an equation for the sine curve in the form y=asinb0?
a. y=2sin50
b. y=5sinpi0
c. y=5sin20
d. y=5sin1/2 0
Answer:
c is correct
Step-by-step explanation:
if u have the equation y = a sin b (x),
a is the amplitue (regardless of + or - before it) and 2pi / b = period. so we can deduce that a = +5 or -5 and b = 2, but then it says a>0, so therefore a must be 5 and b is still 2, so the equation is y= 5 sin2(O)
Pi approx A cylinder has a height of 20 yards and a diameter of 18 yards . What is its volume ? Use 3.14 and round your answer to the nearest hundredth .

3. Identify the pair of angles as complementary, supplementary, both, or neither.
a. supplementary
b. complementary and supplementary
c. neither
d. complementary
Answer:
D) Complementary
Step-by-step explanation:
Angles are complementary if they add up to 90°. The image shown showcases that the angles are 90° because of the box on the corner.
Supplementary means it adds up to 180° which would be a straight line, this is not the case where this is shown.

no links picture above
Answer:
C) 5x + 13x = 180
Step-by-step explanation:
As, the sum of the angles of the above diagram is 180 °
So if we add them we get 180°
So, 5x + 13x = 180°
So option (C) is right
