The simple interest I ( in dollars) for a savings account is jointly proportional to the product of the time t (in years) and th

In-s [12.5K]

Answer:

Part a) The constant of variation is $r=0.0567$ or $r=5.67\%$

Part b) $I=\$662.03$

Step-by-step explanation:

Part a) Find the constant of variation.

we know that

The simple interest formula is equal to

$I=P(rt)$

In this linear direct variation the constant r represent the constant of proportionality

where

I is the Interest Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=5/12\ years\\ P=\$3,892\\ I=\$92\\r=?$

substitute the values and solve for r

$92=3,892(r(5/12))$

$r=(92*12)/(3,892*5)$

$r=0.0567$

Part b) what will the interest be after 3 years

in this part we have

$t=3\ years\\ P=\$3,892\\ I=?\\r=0.0567$

substitute the values

$I=3,892(0.0567*3)=\$662.03$

If two lines are cut by a transversal such that corresponding angles are NOT congruent, what must be true? Justify your response

Ivahew [28]

Answer and Step-by-step explanation:

what must be true is that this particular two lines are not a set of PARALLEL lines. When the lines are parallel, the corresponding angles are congruent and the then the pairs of consecutive angles formed are supplementary .

If we are takling about corresponding angles, they will not be congruent if the lines are not parallel

Using the right triangle below find the cosine of angle A.

svetlana [45]

For the given triangle, the cosine of angle A equals $\frac{1}{2}$ .

Step-by-step explanation:

Step 1; In the given triangle, the opposite side has a length of 9 units, the adjacent side has a length of 3√3 units while the hypotenuse of the triangle measures 6√3 units. To calculate the cosine of angle A we divide the adjacent side by the hypotenuse side.

cos A = $\frac{adjacent side}{hypotenuse}$ .

Step 2; Length of the adjacent side = 3√3 units.

Length of the hypotenuse side = 6√3 units.

cos A = 3√3 / 6√3

cos A = $\frac{1}{2}$ .

To check we also have A = 60° and cos 60° = $\frac{1}{2}$ .
