To do that we have to add 2+7=9
Next step is to divide 72 by 9
72:9=8 - its how many pounds its in"1"
Finally we can multiply
2*8=16
7*8=56 - its the answer
Answer:
y + 1 = 3(x + 8)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 3 and (a, b) = (- 8, - 1) , thus
y - (- 1) = 3(x - (- 8)), that is
y + 1 = 3(x + 8)
Sum of angles of a triangle = 180
a+b+c=180
a + (5a) + (4a-13) = 180
Simplify and solve for a:
10a-13=180
10a=193
a=19.3
b=5*19.3=96.5
c=4*19.3-13=77.2-13=64.2
Check: a+b+c=19.3+96.5+64.2=180 ok.
Answer:
1 (give brainliest plss)
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 5 • -8 = -40
Step-2 : Find two factors of -40 whose sum equals the coefficient of the middle term, which is -3 .
-40 + 1 = -39
-20 + 2 = -18
-10 + 4 = -6
-8 + 5 = -3 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -8 and 5
5x2 - 8x + 5x - 8
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (5x-8)
Add up the last 2 terms, pulling out common factors :
1 • (5x-8)
Step-5 : Add up the four terms of step 4 :
(x+1) • (5x-8)
Which is the desired factorization
It is given in the question that the end of a pendulum with a length of 21 cm travels an arc length of 24 cm.
So here radius is 21 cm and the arc length is 24 cm .
Now we use the arc length formula , which is
Where s is the arc length and r is the radius.
Substituting these values, we will get
And now we need to convert radian to degree, and for that we have to multiply by 
That is
