3.7
<h3>What are the
simplified mathematical expressions ?</h3>
Scientific notation is used to simplify large numbers in smaller numbers. In order to write a number in scientific notation , the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
(8.6 x 
) . (9.1 x 
)
= (8.6 x 9.1) x 
= 78.26 x
= 7.8 x 10
(6.9 x 
) . (4.8 x )
= 33.12 x 
3.3 x
(3.7 x 
) . (4.6 x ) ÷ (1.4 x 
) . (5.7 x 
)
= 1.7 x 10 ÷ 8 x10²
0.21 x 
2.1 x
(3.1 x ) . (5.3 x 
) ÷ (7.3 x ) . (6.1 x 
) = 3.7

Answer:
Part 1) The measure of angle A is 
Part 2) The length side of a is equal to 
Part 3) The length side of b is equal to 
Step-by-step explanation:
step 1
Find the measure of angle A
we know that
The sum of the internal angles of a triangle must be equal to 180 degrees
so
substitute the given values
step 2
Find the length of side a
Applying the law of sines
substitute the given values
step 3
Find the length of side b
Applying the law of sines
substitute the given values
Answer:
The worth of the car after 6 years is £2,134.82
Step-by-step explanation:
The amount at which Dan buys the car, PV = £2200
The rate at which the car depreciates, r = -0.5%
The car's worth, 'FV', in 6 years is given as follows;
Where;
r = The depreciation rate (negative) = -0.5%
FV = The future value of the asset
PV = The present value pf the asset = £2200
n = The number of years (depreciating) = 6
By plugging in the values, we get;
The amount the car will be worth which is its future value, FV after 6 years is FV ≈ £2,134.82 (after rounding to the nearest penny (hundredth))
Answer:
C: y+7=2/5(x+4)
Step-by-step explanation:
The point-slope form of the equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
You are given m=2/5 and (h, k) = (-4, -7). Put these numbers into the form and simplify the signs:
y -(-7) = 2/5(x -(-4)) . . . . . numbers put into the form
y +7 = 2/5(x +4) . . . . . . . signs simplified . . . . matches choice C
