Answer:
1/2
Step-by-step explanation:
quadratic equation is ax²+bx+c=0
Products of roots is c/a
Sum of roots is -b/a
On comparing the above equation with general equation we have
a=1
b=-(3k)
c=-(k+2)
Now it is given that sum of roots and product of roots is equal
So,
-b/a=c/a
-b=c
-[-(3k)]=-(k+2)
3k=-k-2
3k+k=-2
4k=-2
k=-1/2

Answer:
cos 25° = X/11
and
sin 65° = X/11
is this good enough or do you need more workings?
Answer:
C = 90°
Step-by-step explanation:
The interior angles in every triangle are equal to 180 degrees. So, this means that
[tex] \alpha + \beta + \gamma \\ = 180 \: degrees[/tex]
Which means that A + B +C = 180 degrees
A=25°
B = 65°
C =?
C = 180° - (A + B)
C = 180° - (25° +65°)
C = 180° - 90°
C = 90°

Two angles are complementary. One angle is 52°. How many degrees is the other angle?
Answer:
B
Step-by-step explanation:
Complementary angles sum to 90° then the other angle is
90° - 52° = 38°
Answer:
B 38°
Step-by-step explanation:
complementary angles are two angles that up to 90°, since we know one is 52°, 90-52=38, so your answer is 38

III. Individuals who take risks can gain great profits.
a.
I and II
b.
II only
c.
II and III
d.
I and III
Please select the best answer from the choices provided
A
B
C
D
Answer:
A
Step-by-step explanation:
In the beginning, there was little or no private ownership. Cucumbers are a pretty interesting example. We had an exchange student who said all the cucumbers were raised on one collective the size of 10 sections. He didn't know how many people were on that farm but it employed many people. The farm was located near a very large city so transportation was not a problem. The state owned the farm.
The second one is a result of the first one. Collectives are not meant to benefit the individual. They benefit everyone.
Three is a characteristic of free enterprise.

Help this is due in 2 minutes
Answer:
The value of the machinery after 5 years is $236.20
Step-by-step explanation:
Generally, we have the depreciation exponential expression as;
V(t) = I (1 - r)^t
V(t) is the value of the machinery at a point in time
I is the initial value or the cost of the machinery when bought which is $400
r is the rate of decrease which is 10% and is same as 10/100 = 0.1
t is the time which is 5 years
Substituting these values;
V(5) = 400( 1 - 0.1)^5
V(5) = 236.196
to the nearest vent, this is $236.20
