Answer:
Option B. 1
Step-by-step explanation:
We have
Two side lengths of a triangle of 10 cm and 8 cm, and the angle between the sides of the triangle measures 40°
so
Applying the law of cosines find out the length of the third side
Let
c ----> the length of the third side of triangle


so
The measurements of the three sides of the triangle are unique
therefore
Using these measurements, only one triangle can be constructed
Answer:
1464
Step-by-step explanation:
(110-85)/2 * (85+110)/2 + (((110-85)/2)^2*pi)/2 using Calculus lvl 5.6
thus getting 1464 rounded
Answer:
y = -1/6x-1 is perpendicular to y=6x-2 that intersects (6,-2)
Step-by-step explanation:
Answer:
Options a, d and e
Step-by-step explanation:
We check the validity of each of the options.
Kindly note that we can express the equation fully and we have;
y-3 = -2x-10
y = -2x -10 + 3
y = -2x -7
So let’s now evaluate the options.
(a) Insert the value of x at this point, if it gives the value of y, then it’s on the line
the value of x to insert is -5 here.
Thus ; y = -2(-5)-7 = 10-7 = 3
since y is 3, then it is on the line
(b) same as a
insert x = 5
y = -2x-7
y = -2(5) -7
y = -10-7 = -17
This is definitely not on the line as the value of y gotten does not correlate with what was given
c. To get this , compare with the standard form of
y = mx + c
where m is slope
Here our m is -2 , so this is definitely wrong
d) From above , we can see that this is correct
e) compare this with y = mx + c
c is our intercept and this is equal to -7 which makes this option also correct
