Do you remember what the sine of an angle is ? If the angle is in a right triangle, then the sine of the angle is (the opposite side) divided by (the hypotenuse). So in this triangle, sin(38) = 24/x . And. X = 24/sin(38) . You can find sin(38) with your calculator or on line, and once you have that number, you're just a simple division away from knowing 'x'.
Answer:
12
Step-by-step explanation:
x=(-10×1+23×2)÷(2+1)=36/3=12
<span>Y=2x-5
-8x-4y= -20
---------------------------
Substitute 2x-5 for y in </span> -8x-4y= -20
<span>-8x-<span>4<span>(<span>2x-5</span>)</span></span></span>=-<span>20
</span>-16x+20=-<span>20
</span>---------------------------------------
Add -20 on each side
<span>-16x+20+-20</span>=-<span>20+-20
</span>-16x = -40
------------------------------------------------
Divide each side by -16
16x / -16 = -40 / -16
x = 5/2 or 2.5
now we have x
===============================================================
To find Y Substitute 2.5 for X in y=<span><span>2x-</span><span>5
y = 2(2.5)-5
y = 0
---------------------------------------
X = 5/2 or 2.5 and Y = 0</span></span>
It’s the quadratic formula because it’s give directly the zeros of a function
In cases of variable interest rates, such as those used on certain credit cards, the card’s interest rate may be expressed as the prime rate plus a set percentage. This means the rate rises and falls with the prime rate but always remains a fixed percentage above the prime rate at all times.
So to find the maturity value The formula is
Mv=p (1+r×t)
Mv maturity value?
P amount borrowed 50000
R interest rate 10.56% (7.35%+3.21%)
T since the interest is ordinary we divide the number of days by 360
175/360
Mv=50,000×(1+0.1056×(175÷360))
Mv=52,566.67
