Answer:
C and D
Step-by-step explanation:
see picture (plotted it to clarify both functions)
We are given with the expression or equation s<span>in2x cosx + cos 2x sin x = √3/2. The expression can be patterned from the trigonometric identity sin (a + b) = sin a cos B + cos A sin B. In this case, the expression is equal to sin 3x = sqrt 3 /2. using arc sign, x is equal to pi/9 </span>
B
a+c=100
3a +2c = 275
(3*75) + (2*25) = 275
99 R 4
499 divided by 5 = 99 R4

</span>60 is 10
times as much as is what value?</span>
<span><span>2.
</span>60 is 1/10
of what value?</span>
To interpret these given
problems we can first analyse these given word problems to a mathematical expression.
Hence the given becomes then;
Let N be the unknown value.
<span><span>
1.
</span>10 x N = 60</span>
<span><span>2.
</span>N / 10 = 60</span>
To solve these equations we
just have to find the unknown or N.
<span><span>
1.
</span>10N = 60</span>
<span><span>a.
</span>N = 60/10</span>
<span><span>b.
</span>N = 6</span>
<span><span>
c.
</span>10 x 6 = 60</span>
<span><span>2.
</span>N / 10 = 60</span>
<span><span>
a.
</span>N = 60 x 10</span>
<span><span>b.
</span>N = 600</span>
<span><span>c.
</span>600 / 10 =
60</span>
