(6.2x10^17)+(1.2x10^15)
Answer:
621200000000000000
Step-by-step explanation:
(6.2×10^17 )+(1.2×10^15)
6.2×100000000000000000+1.2×10^15 ≈6.212⋅10^ 1 7
620000000000000000+1.2×10^15 ≈6.212⋅10^ 1 7
620000000000000000+1.2×1000000000000000≈6.212⋅10^ 1 7
620000000000000000+1200000000000000≈6.212⋅10^1 7
621200000000000000
Answer:
6.212×10^17
Step-by-step explanation:
[tex] = ( 6.2 \times {10}^{17} ) + (1.2 \times {10}^{15} )[/tex]
[tex] = (620 \times {10}^{15}) + (1.2 \times {10}^{15} )[/tex]
[tex] = 620 \times {10}^{15} + 1.2 \times {10}^{15} [/tex]
[tex] = (620 + 1.2)\times {10}^{15} [/tex]
[tex] = 621.2\times {10}^{15} [/tex]
[tex] = 6.212 \times {10}^{17} [/tex]

Why are the triangles below congruent?
Answer:
SSS
Step-by-step explanation:
We know this triangles are congruent due to SSS because AB is congruent to CD because of the tick marks. AB is also congruent to BC due to the tick marks. BD Is congruent to BD by the reflexive property. Therefore, triangle ADB is congruent to triangle CDB by SSS.

A newspaper is launching a new advertising campaign in order to increase the number of daily subscribers. The newspaper currently (t0) has 26,000 daily subscribers and management expects that number, S(t), to grow at the rate of subscribers per day, where t is the number of days since the campaign began. How long (to the nearest day) should the campaign last if the newspaper wants the number of daily subscribers to grow to 49,000?
Answer:
57 days
Step-by-step explanation:
Given that:
t(0) = 26000
Growth rate (S'(t)) = 80t^1/2
Targeted number of subscribers = 49000
Take the integral of the growth rate :
∫80t^1/2dt = [(80t^(1/2 + 1)) / 1/2 + 1] + C
[(80t^(1/2 + 1)) / 1/2 + 1] + C = (80t^3/2) / 3/2 + C
(80t^3/2) * 3/2 + C = (160/3)t^3/2 + C
(160/3)t^3/2 + C
Let C = t(0)
(160/3)t^3/2 + 26000 = 49000
(160/3)t^3/2 = 49000 - 26000
(160/3)t^3/2 = 23000
Multiply both sides by 3/160
t^3/2 = 23000* 3/160
t^3/2 = 69000/160
t^3/2 = 431.25
t^(3/2 * 2/3) = 431.25^2/3
t = 57.080277
t = 57 days (approx.)

Graph the line passing through (-6,-3) whose slope is m=2
Answer:
Start at (−6,−3) and count up 2 units and right 1 unit to find a second point. Connect the two points with a line to find the graph.
Step-by-step explanation:
Start by plotting the point (−6,−3). Use the slope formula m=rise/run to identify the rise and the run.
m=2
rise/run = 2/1
rise = 2
run = 1
Start at (−6,−3) and count up 2 units and right 1 unit to find a second point. Connect the two points with a line to find the graph.
What is the length of a segment with endpoints at F(6, 4) and G(14, 19)? Round to the nearest whole number.
Answer:
17
Step-by-step explanation:
d = √( (x₂ - x₁)² + (y₂ - y₁)² )
= √( (14 - 6)² + (19 - 4)² )

In a circle with a radius of 3 ft, an arc is intercepted by a central angle of 120 degrees.
What is the length of the arc?
Answers:
6.28 ft 09.42 ft
18.84 ft
28.26 ft
Answer:
A) 6.28ft
Step-by-step explanation:
r = 3ft
θ = 120°
Arc length = θ ⋅ (2πr/360)
Arc length = 120° ⋅ (2π ⋅ (3/360))

Let A and B be events with P(A) = 0.7 and P(A ∩ B) = 0.3. For what value of P(B) will A and B be independent?
Answer:
The value of P(B) for independent events = 0.429
Step-by-step explanation:
Given;
P(A) = 0.7
P(A ∩ B) = 0.3
A and B will be independent if event A will occur and B will also occur, ie A and B will occur independently.
P(A) and P(B) = P(A ∩ B)
[tex]P(B) = \frac{ P(A\ n\ B) }{P(A)}\\\\ P(B) = \frac{0.3}{0.7}\\\\P(B) = 0.429[/tex]
Therefore, the value of P(B) for independent events = 0.429

Rewrite the following without an exponent:
4^-4. (-4 is the exponent).
Thank you!
Answer:
[tex]\frac{1}{256}[/tex]
Step-by-step explanation:
The [tex]4^{-4}[/tex] without exponents is 1/256.
Given,
[tex]4^{-4}[/tex]
We need to write the given expression without exponents.
What are exponents?
Exponents are power to a base value.
Example:
a² and b³
a and b are base
2 and 3 are exponents.
We can a fraction into an exponents form and vice versa.
Example:
1/a = [tex]a^{-1}[/tex]
We have,
[tex]4^{-4}[/tex]
Changing into a fraction form
= 1/[tex]4^{4}[/tex]
Find [tex]4^{4}[/tex].
[tex]4^{4}[/tex] = 4 x 4 x 4 x 4 = 16 x 16 = 256
Now,
= [tex]4^{-4}[/tex]
= 1/[tex]4^{4}[/tex]
= 1/256
We get,
= 1/256
Thus the [tex]4^{-4}[/tex] without exponents is 1/256.

One-sided Limit
Given a piecewise function, we can find the limit when the variable approaches a specific value in the boundary of two pieces.
Special care must be taken to determine what function will be used to calculate the limit according to the conditions of the independent variable.
The given function p(t) has 3 pieces or subfunctions according to different conditions of t. We need to calculate:
[tex]\lim _{x\to 2^{-}}p(t)[/tex]
We must find the subfunction where a value of t is close to 2 but is less than 2.
The correct subfunction is
[tex]p(t)=t^3\qquad -2\le t\le 2[/tex]
Taking the limit:
[tex]\lim _{x\to 2^{-}}p(t)=\lim _{x\to 2}t^3=2^3=8[/tex]
Correct option: c. 8

Find the value of x in the triangle shown below. x = 56° 99°
Answer:
x = 25 degrees
Step-by-step explanation:
All angles in a triangle should add up to 180 degrees. So to solve for x, set up an equation where all three angles added up equals 180.
180 = 99 + 56 + x
180 = 155 + x
25 = x
The unknown angle is equal to 25 degrees.
