Answer:
Step-by-step explanation:
a) Given:
u=
v=<-7,5>
v-5u=<-7,5>-5<-4,8>
v-5u=<-7,5>+<20,-40>
v-5u=<-7+20,5-40>
v-5u=<13,-35>
b)
The magnitude of this vector is
||v-5u||=
||v-5u||=
||v-5u||=
||v-5u||=
to the nearest tenth
Answer:
Two angles are complementary if their measures add up to 90°. In the diagram, ∠ADB and ∠BDC are complementary.
Step-by-step explanation:
100 dollars should be a one time fee so that has to be added to the equation, and since it is a one time fee it should not have a variable next to it.
It also says that you have to pay 720 dollars per month, so it has to have a variable next to it to show the number of months that she needs to pay that amount of money.
The answer should be D.
y= 720x +100

We know that
the formula of the <span>the sum of the arithmetic sequence is
Sum=n*(a1+an)/2
n=36
a1=3
a36=?
find a36
an=a1+(n-1)*d
for n=2 a2=9
9=3+(2-1)*d----> 9=3+d----> d=6
so
for n=36
a36=a1+(36-1)*6----> a36=3+35*6----> a36=213
</span>Sum=n*(a1+an)/2-----> 36*[3+213]/2----> 3888
the answer is
3888
