Answer:
=5.1 units
Step-by-step explanation:
To use the sine rule to find the length of c we first need to find the angle at C.
C=180-(13+12)
C=180-25
C=155°
a/Sin A=c/Sin C
Calculating for the value of c using the sine rule:
12/Sin 13=c/Sin 155
c=12 sin 155
=5.07 units
Thus to 1 decimal places, the value of c is 5.1 units.
Width of 76 inches and length of 3
or width of 77 and length of 2
or width of 78 and length of 1
they all have a perminiter of 158 and all widths exceed 75
Answer:
4.4 days
Step-by-step explanation:
375 x 0.14 = 52.5
300 - 52.5 = 247.5
247.5 / 55.98 = 4.42 days
Answer: B
Step-by-step explanation:
When you factor an expression, you want to take out a factor of the numbers and variables.
Since this expression is a bit hard to factor as itself, we can FOIL the answers to see the correct expressions.
(4x-5)(4x-5)
16x²-20x-20x+25
16x²-40x+25
Answer:
a. yes
b. no
c. no
d. no
e. yes
Step-by-step explanation:
Here, we want to answer yes or no for each of the numbers
a) Yes
If we compare with the general form
y = mx + b
m
is slope and b is y-intercept
so, 2 is slope and 3 is y intercept; so 3 in y-intercept is (0,3)
b. No
This is the point-slope form we are trying to
get
Evaluating this, we have that
y-3 = 2x - 6
y = 2x-6 + 3
y = 2x-3
c) NO
Just insert the values and check here
-1 = 2(5) + 3
it does not work
d) No
Substitute
-4 = 2(-5) + 3
e) Yes
This is the point-slope form
y + 3 = 2x + 6
y = 2x + 6-3 = 2x + 3
