Four less than twice a number is fifty

Mathematics
2 answers:
Dvinal [7]3 years ago
6 0

Answer:

2a - 4 = 50

Step-by-step explanation:

Less than means that you subtract 4.

Twice a number just means that you multiply a number by 2.

And we know that all of that equals 50.

If you want to solve it..

2a - 4 = 50

    +4     +4

-----------------

2a = 54

Divide both sides by 2. 54/2 = 27

a = 27

Find the value of c that makes x^2+26x+c a perfect-square trinomial.
MakcuM [25]
C = 169

square is (x + 13)^2

Explanation:

In the form:
ax^2+ bx +c
to complete the square a = 1 is required.
c = (b/2)^2
the square term is b/2
x^2 + 26x + c
a = 1 so we are okay to complete the square.
b = 26
c = (26/2)^2 = 13^2 = 169
finally to complete the square:
x^2 + 26x + 169 = (x+b/2)^2 = (x+13)^2

What is the equation if the horizontal line that passes through (5,-6)
Tema [17]

Answer:

y = -6

Step-by-step explanation:

On the coordinate plane, the vertical axis (up and down) is the y-axis and the horizontal axis (side to side) is the x-axis.  However, when there is a horizontal line on the graph, it represents a value of y that is true for any value of 'x'.   In the same respect, a vertical line is a value of x that is true for any value of 'y'.  In the case of the point (5, -6), a horizontal line would have to be y = -6 in order to pass through the point and cross the coordinate plane from left to right.

Find d^2y/dtheta^2 if y=sin^5
castortr0y [4]

Answer:

20 sin³O. cos²O - 5sin⁵O

Step-by-step explanation:

y = sin⁵O

Using the Chain Rule

dy/dO = 5 sin⁴O cosO

Using the Product / Chain rules:

d²y/dO² = 20 sin³O.cosO . cos O+ 5 sin⁴O * - sin O

= 20 sin³O. cos²O - 5sin⁵O
