The last six numbers are:
390, 395, 400, 405, 410, 415
Hope this helps☺
-4.6(2.2x+3y=15.25) = -10.12x - 13.8y = -70.15
2.2(4.6x+2.1y=18.325) = 10.12x - 4.62y = 40.315
simplify
-4.62y = -29.835
divide both sides by -4.62 to isolate y
y= 6.46
2.2x + 3 (6.46) = 15.25
2.2x + 19.38 = 15.25
subtract 19.38 to both sides
2.2x = -4.3
divide 2.2 to both sides
x= -1.95
I hope that this helped :)
Answer:
0
Step-by-step explanation:
Substitute the given values for a and b into the expression
(18 + 14) - (18 - 14)²
= × 32 - 4²
= 16 - 16
= 0
Answer:
15 years
Step-by-step explanation:
Since we're looking for time, we can use the formula t = A / Pr, which would be:
t = 6000/(7255 x 5.5%)
Converting the percentage into decimal form
t = 6000/(7255 x 0.055)
We can then solve to get:
t = 6000/399.025
t = 15.03665183...
Meaning it would take 15 years for an interest of 5.5% on $6,000 to reach $7,255. Not very worth $1,255 extra if you need that 6k for rent.
Answer:
Sin, Cos, Tan and others are used to calculate the ratios of the sides of a right angled triangle by taking a certain angle as the angle of reference.
On the other hand, Sin‐¹, Cos‐¹ and Tan-¹ are used to find the reference angle used to calculate the ratio of sides.
For this question,
we need to find which option should used to calculate the angle the slide makes with the vertical support.
So the option will have to be either A, C or E.
here, the base is 2.81m and hypotenuse is 3.64m.
we know, Cos = base / hypotenuse
So the angle is given by Cos-¹(2.81/3.64)
Option C
