Answer is C. -1023
Answer:
4.485
Step-by-step explanation:
[divide 17 by 4]
[ ]
Now, Midpoint of 4.25 and 4.472 =
Number between 4.25 and 4.472 =4.485
Or number between and is 4.485.
(4 x 4) - (4/4)
= 16 - 1
= 15
Answer:
23) option c
JL ≈ 9.3
25) option c
y ≈ 9.6
Step-by-step explanation:
<h3>25)</h3>
Given in the question that,
cos(21°) = 9 / y
y = 9/cos(21°)
y = 9.64
y ≈ 9.6(nearest tenth)
<h3>23)</h3>
Given in the question that the hypotenuse of right angle triangle = 12
To find,
height of the right angle triangle
angle k = 39°
so by using trigonometry identity
cos(39) = opp/hypo
cos(39) = JL / KL
JL = cos(39)(12)
JL = 9.32
JL ≈ 9.3

<u>Answer:</u>
The interest after 3 years is $360
<u>Explanation:</u>
Given the principal amount (P) = $3000
Rate of interest (R) = 0.04
Time period (T) is given as 3 years
The Simple Interest is calculated by the formula;

Substituting the values in the above formula,

SI = $360
Therefore, the interest after 3 years is $360
