X^2+20x+c find the value of c that makes a perfect square trinomial

Mathematics
1 answer:
ollegr [7]3 years ago
3 0

Answer:

This means c=100. The factored form is (x+10)^2.

Step-by-step explanation:

A perfect square is a trinomial that factors into the form (x+a)^2. To find the value of C to finish the perfect square divide 20 by 2 and square it.

20/2 = 10

10*10=100

This means c=100. The factored form is (x+10)^2.

Answer:

F(4) = 9

Step-by-step explanation:

Notice that for f(4), we need to use the function definition for the partitioned Domain that includes x = 4, and that is the expression :

f(x) = x^2-7

Therefore:

f(4) = 4^2-7 = 16-7 =9

From the earth, the moon subtends an angle of approximately 0.5°. If the distance to the moon is approximately 240,000 miles, fi
konstantin123 [22]

Answer:

2100 miles.

Step-by-step explanation:

Given:

Diameter to the moon = 240000 miles

∅ = 0.5 °

The subtended angle by an arc is given as:

S = r∅

Where

r = radius of the circle

Therefore,

D = 240,000 x (0.5 x π rads)/180

= 2094 miles

= 2100 miles.
