Trig please help

Olenka [21]

Answer:

One

Step-by-step explanation:

14/sin(54) = 7/sinC

sinC = 0.4045084972

C = 23.86, 156.14

Since 156.14+54 = 210.14 > 180

Only one triangle can be formed with angle 23.86° at C

The perimeter P of a square (measured in inches) is expanding in size at a constant rate of change of 4 inches per inch with res

vivado [14]

Answer:

a. 10 inches

b. 8 inches

c. $\frac{dP}{ds} = 4$

Step-by-step explanation:

a. At side 0, perimeter is 0*4 = 0 in. At side 2.5 inches, perimeter = 2.5*4 = 10 inches, a change of 10 - 0 = 10 inches

b. At side 1, perimeter is 1*4 = 4 inches. At side 3 inches, perimeter = 3*4 = 12 inches, a change of 12 - 4 = 8 inches.

c. We can express the change in the square's perimeter P in terms of the change in the square's side length s as

$\frac{dP}{ds} = 4$

Given f(x) and g(x) = f(x) + k, use the graph to determine the value of k.

Evgesh-ka [11]

Answer:

k = 3

Step-by-step explanation:

The value of k is the amount by which the function f(x) is translated upward to give the function g(x). We can compare y-intercepts to see that the y-intercept of g(x) is 5 -2 = 3 units more than the y-intercept of f(x). This means ...

g(x) = f(x) +3

Comparing to ...

g(x) = f(x) +k

we see that k = 3.

What equation results from completing the squre and then factoring x^2+10=15

nlexa [21]

For this case we must complete squares:

$x ^ 2 + 10x = 15$

We add the square of half the coefficient of the term "x",

$(\frac {b} {2a}) ^ 2$ on both sides of the equation:

$x^2+10x+(\frac {10} {2 (1)}) ^ 2 = 25 + 15\\x ^ 2 + 10x + 5 ^ 2 = 25 + 15$

According to the perfect square trinomial we have:

$(a + b) ^ 2 = a ^2 + 2ab + b ^ 2$

Rewriting the expression we have:

$a = x\\b = 5\\(x + 5) ^ 2 = 25 + 15\\(x + 5) ^ 2 = 40$

ANswer:

$(x + 5) ^ 2 = 40$
