Answer:

The slope of this line would be undefined.

Step-by-step explanation:

In order to find the slope of a parallel line, we first need to find the slope of the original line. We can do this by using the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (7 - 3)/(-4 - -4)

m = (7 - 3)/(-4 + 4)

m = 4/0

Since we cannot divide by 0, we know the slope to be undefined. Also, since parallel lines have the same slope, we know the second line to also have an undefined slope.

Randall has an account balance of $675.54 in a savings account that earns interest at a rate of 2.5% compounded twice a year. If
Alex_Xolod [135]
To calculate amount accrued after a given period of time we use the compound interest formula: A= P(1+r/100)∧n where A i the amount, P is the principal amount, r is the rate of interest and n is the interest period.
In the first part; A= $ 675.54, r= 1.25% (compounded semi-annually) and n =22 ( 11 years ),  hence, 675.54 = P( 1.0125)∧22
   = 675.54= 1.314P
 P= $ 514.109 , therefore the principal amount was $ 514 (to nearest dollar)
Part 2
principal amount (p)= $ 541, rate (r) = 1.2 % (compounded twice a year thus rate for one half will be 2.4/2) and the interest period (n)= 34 (17 years×2)
Amount= 541 (1.012)∧34
             = 541 ×1.5
             = $ 811.5
Therefore, the account balance after $ 811.5.

If the smallest angle of a triangle is 20° and it is included between sides of 4 and 7, then (to the nearest tenth) the smallest
lawyer [7]

Answer:

3.5

Step-by-step explanation:

The smallest side of a triangle is formed by the smallest angle in the triangle.

To find the side opposite (formed by) the 20 degree angle, we can use the Law of Cosines. The Law of Cosines states that for any triangle, c^2=a^2+b^2-ab\cos \gamma, where a, b, and c are the three sides of the triangle and \gamma is the angle opposite to c.

Let c be the side opposite to the 20 degree angle.

Assign variables:

  • a\implies 4
  • b\implies 7
  • \gamma \implies 20^{\circ}

Substituting these variables, we get:

c^2=4^2+7^2-2(4)(7)\cos 20^{\circ},\\c^2=16+49-56\cos 20^{\circ},\\c^2=12.377213236,\\c=\sqrt{12.377213236}=3.51812638147\approx \boxed{3.5}

Therefore, the shortest side of this triangle is 3.5.
