Ralph wants to build a rectangular deck with a predefined area of 66 feet squared. One side of the deck will be 5 feet longer than the other. To find the side lengths, he first writes the equation (x)(x+5)=66 and later simplifies (x-6)(x+11)=0 it to , where x is the length of the shorter side. Which of these are the side lengths, in feet, of the rectangular deck? Select all that apply
Answers
Answer:
The shorter side is 6 ft and the longer side is 11 ftStep-by-step explanation:
The options are not given, but we could solve and arrive at an answer
say the shorter side is x
and the longer side is x+5
we know that the area of a rectangle is given as
x*(x+5)=66
open the bracket
x^2+5x=66
x^2+5x-66=0
Find two factors of -66 whose sum equals the coefficient of the middle term, which is 5 .
the factors are 11 and -6
splitting the middle term using the two factors 11 and -6
x2 +11x - 6x - 66=0
x(x+11)-6(x+11)=0
(x-6)=0
x=6
(x+11)=0
x=-11
The shorter side is 6 ft and the longer side is 11 ft

Find the equation of the linear function represented by the table below in slope-
intercept form.
y=Mx+B
Answers
Answer:
y = x + 4
Step-by-step explanation:
Let the equation of the linear function represented by the table is,
[tex]y-y_1=m(x-x_1)[/tex]
where m = slope of the line
And this line passes through the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Slope of the given line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
From the given table two points lying on the function are (-4, 0) and (1, 5).
Slope 'm' = [tex]\frac{5-0}{1+4}[/tex] = 1
Therefore, equation of the linear function passing through (1, 5) and slope 1 will be,
y - 5 = (x - 1)
y = x + 5 - 1
y = x + 4

Equations as per ratio and solution for each
c. ..................................
25 ÷ 2 1/2 = 100 ÷ x25 ÷ 5/2 = 100 ÷ xx = 100×5/2÷25x = 10100 yards in 10 seconds

480 ÷ 4 = z ÷ 1120 = zz = 120120 heartbeats in 1 minute
Answer:
c. y = 10 secs.d. z = 120 heartbeatsStep-by-step explanation:
c. ratio and proportion:
25 yards = 100 yards
2.5 sec. y sec.
cross multiply:
100 (2.5) = 25 (y)
simplify:
y = 250 / 25
y = 10 secs.
------------------------------------------
d. ratio and proportion:
480 heartbeats = z heartbeats
4 mins. 1 min.
cross multiply:
4 (z) = 480 (1)
simplify:
z = 480 / 4
z = 120 heartbeats

d)rational
e)irrational
f)real
Answers
Answer: (6) a (7) b (8) d (9) d
Step-by-step explanation:
a) Natural Numbers: 1, 2, 3, ...
b) Whole Numbers: 0, 1, 2, 3, ... (add zero to the Natural numbers)
c) Integers: ..., -3, -2, -1, 0, 1, 2, 3, ... (add negatives to the Whole numbers)
d) Rationals: Add terminating and repeating decimals to Integers.
************
e) Irrationals: Non-repeating decimals that are non-terminating. This is its own category so cannot be a Rational number or above.
f) Real Numbers: ALL of the above (a - e) are Real numbers.
6) The variable (d) represents the number of dogs. You cannot have a fraction of dog (rational), a negative number of dogs (integer), or zero dogs (whole) so the variable will be a NATURAL number.
7) The variable (b) represents the number of baths. You cannot have a fraction of a bath (rational), a negative number of baths (integer), but you can have zero baths so the variable will be a WHOLE number.
(8) The variable (n) represents the number of nails. You can have a fraction of a nail so the variable will be a RATIONAL number.
(9) The variable (h) represents the number of pounds of hair. You can have a fraction of a pound so the variable will be a RATIONAL number.

Find cosα given that sinα = 5/13 and α is in quadrant II
Answers
Answer:
cos α = - [tex]\frac{12}{13}[/tex]
Step-by-step explanation:
Since α is in second quadrant then cosα < 0
Using the identity
sin²α + cos²α = 1 then
cosα = - [tex]\sqrt{1-sin^2\alpha }[/tex]
= - [tex]\sqrt{1-(\frac{5}{13})^2 }[/tex]
= - [tex]\sqrt{1-\frac{25}{169} }[/tex]
