AC is the adjacent leg to C and BC is the hypotenuse. So we're talking about the cosine:

$\cos C = \dfrac{AC}{BC}$

For part 2, the co in cosine means "complementary" so cos x equals the sine of the complementary angle, that's going to be

$\sin y$

Ebony but a four year treasury note that pay the equivalent of 3.8% simple interest. She invested $3000 more in a 9 year bond e

Anastasy [175]

Treasury bond's invested amount is "$7000" and Bond's invested amount is "$10000",

Let,

The amount invested in treasury note will be = x
The amount invested in bond will be = (x + 3000)

then,

→ $\frac{x\times 4\times 3.8}{100} +\frac{(3000+x)\times 9\times 4.6}{100}=5204$

→ $\frac{15.2x}{100}+\frac{(3000+x)\times 41.4}{100} =5204$

→ $\frac{15.2x}{100} +\frac{124200+41.4x}{100} =5204$

→ $\frac{15.2 x+124200+41.4x}{100} = 5204$

→ $56.6x+124200=520400$

→ $56.6x=520400-124200$

→ $56.6x=396200$

→ $x = \frac{396200}{56.6}$

→ $= 7000$

Amount invested in bond will be:

= $x+3000$

= $7000+3000$

= $10000$

Thus the above is the correct answer.

Which number can each term of the equation be multiplied by to eliminate the fractions before solving-3/4m-1/2=2+1/4m

densk [106]

<h2>Hello!</h2>

The answer is: 4

The smallest whole number we can use to multiply each term in order to eliminate the fractions is 4:

Multiplying each side of the equation by 4, we have:

$(\frac{-3m}{4}-\frac{1}{2})*4=(2+\frac{1}{4})*4\\\\\frac{-12m}{4} - \frac{4}{2} = 8+\frac{4m}{4}\\-3m-2=8+m\\-8-2=m+3m\\4m=-10\\m=\frac{-10}{4}=\frac{-5}{2}\\\\m=\frac{-5}{2}$

Have a nice day!

Complete the equation of the line whose slope is 5 and y intercept is (0,4)

irina1246 [14]

y = 5x + 4 is the equation of the line whose slope is 5 and y intercept is (0,4)

Solution:

Given that, we have to write the equation of the line whose slope is 5 and y intercept is (0,4)

The equation of line in slope intercept form is given as:

y = mx + c ---- eqn 1

Where, "m" is the slope of line and "c" is the y - intercept

Given that, slope = m = 5

y intercept is (0, 4)

So, c = 4

Substitute c = 4 and m = 5 in eqn 1

y = 5x + 4

Thus the equation of line is found
