Answer:

$793.80

Step-by-step explanation:

You want to calculate the interest on $630 at 6.5% interest per year after 4 year(s).

The formula we'll use for this is the simple interest formula, or:

<em>I = P x r x t</em>

<em>Where: </em>

<em> </em>

<em>P is the principal amount, $630.00. </em>

<em>r is the interest rate, 6.5% per year, or in decimal form, 6.5/100=0.065. </em>

<em>t is the time involved, 4....year(s) time periods. </em>

<em>So, t is 4....year time periods. </em>

<em>To find the simple interest, we multiply 630 × 0.065 × 4 to get that: </em>

<em> </em>

<em>The interest is: $163.80 </em>

<em>Usually now, the interest is added onto the principal to figure some new amount after 4 year(s), </em>

<em>or 630.00 + 163.80 = 793.80. For example: </em>

<em> </em>

<em>If you borrowed the $630.00, you would now owe $793.80 </em>

<em>If you loaned someone $630.00, you would now be due $793.80 </em>

<em>If owned something, like a $630.00 bond, it would be worth $793.80 now.</em>

PLEASE HELP!!
PSYCHO15rus [73]

<u><em>Answer:</em></u>

The bird is approximately 9 ft high up in the tree

<u><em>Explanation:</em></u>

The required diagram is shown in the attached image

Note that the tree, the cat and the ground form a right-angled triangle

<u>Therefore, we can apply special trigonometric functions</u>

<u>These functions are as follows:</u>

sin(\alpha)=\frac{opposite}{hypotenuse} \\ \\ cos(\alpha)=\frac{adjacent}{hypotenuse} \\ \\tan(\alpha)=\frac{opposite}{adjacent}

<u>Now, taking a look at our diagram, we can note the following:</u>

α = 25°

The opposite side is the required height (x)

The adjacent side is the distance between the cat and the tree = 20 ft

Therefore, we can use the <u>tan function</u>

<u>This is done as follows:</u>

tan(\alpha)=\frac{opposite}{adjacent}\\ \\ tan(25)=\frac{x}{20}\\ \\x=20tan(25) = 9. 32 ft which is 9 ft approximated to the nearest ft

Hope this helps :)

When does the proportion form of newton's second law take the form of an equation?
Brrunno [24]
Newton's law of motion has three parts. The second of which states that the force needed to move an object is directly proportional to the acceleration of the motion. The proportion can be written as,
              F = ka
where k is the constant of proportionality. This can be substituted with the mass of the object such that the equation would become. 
                F = ma
where F is force, m is mass, and a is acceleration.
