Bella has $540 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
Norma-Jean [14]

Step-by-step explanation:

$540 - $353.59 = $186.41

$186.41 - $4.98 = $181.43

$181.43 - $38.67 = $142.8

She has $142.8 left and if she want to buy the outfits for $49.20 she is going to have $93.6 left

C. Find a parametrization for the line segment with endpoints (-1, 3) and (3, -2).
wel

Answer:

x(t) = -1 + 4t

y (t) = 3 - 5t

Step-by-step explanation:

The end points of the line segment are (-1, 3) and (3, -2).

Let a = (-1,3) and b = (3,-2)

Now, find the value of (b-a)

(b-a) = ((3+1), (-2-3))

b-a = (4, -5)

Therefore, the parametrization of the given line segment is

r(t) = a + (b-a)t

r(t) = (-1,3) +(4,-5)t

r(t) = (-1+4t, 3-5t)

We can rewrite this as

x(t) = -1 + 4t

y (t) = 3 - 5t

Find all the square roots of x^2 ≡ 53 (mod 77) by hand. This is my second post. Please explain all the steps how you did this?
sasho [114]

Answer:

Step-by-step explanation:

Given that

x^2 ≡ 53 (mod 77)

Right side has values as

53, 53+77, 53+2(77),+....

We have to find one which is a perfect square.

We have from this series 361 is 19 square

Thus x =19.

Next is x^2=900\\x=30

x^2=2209\\x=47 and so on.

Find the slope of the line that passes through the points (-19, -4) and (13, -17).​
Tasya [4]

Answer:

m = \frac{-13}{32}

Step-by-step explanation:

Two point slope formula = \frac{y_{2} - y_{1}  }{x_{2} - x_{1} }

\frac{-17 + 4}{13 + 19} = \frac{-13}{32}
