F(x) = (-1/2) * (x-3)

y = (-1/2) * (x-3)
⇒ -2y = x - 3
⇒ -2y + 3 = x
⇒ x = -2y + 3

Thus f^-1(x) = -2x + 3

Write an inequality for the given statement: The product of –3 and a number is no more than 15. plzz help i dont have time

ololo11 [35]

We represent the unknown number x. The product of this number and -3 is -3x. This product should be no more than 15. This also means that the product should be less than or equal to 15. This is shown in the inequality,
-3x ≤ 15
The answer is letter B.

The lengths of the three sides of a triangle (not necessarily a right triangle) are 3.16 meters, 8.25 meters and 10.4 meters. wh

Dafna1 [17]

For non-right triangles you must use the "Law of Cosines" and then, the "Law of Sines" to solve this.

a= 8.25m
b= 10.4m
c= 3.16m
∠A= UNKNOWN
∠B= UNKNOWN
∠C=UNKNOWN

Law of Cosines:
c²= a²+b²-2abCos(C)
(3.16)²= (8.25)²+(10.4)²- 2(8.25)(10.4)(cos(C))
9.9856 = 68.0625 + (108.16) - (171.6)(cos(C)
9.9856 = 176.2225- 171.6 cos C
-166.2369= - (171.6(cosC))
cosC= 0.968746503
Take the inverse cosine of that to get the measure of angle C
∠C= 15.95813246°

Now Use law of sines to find ∠B:
$\frac{10.4}{Sin(B)} = \frac{3.16}{sin(15.96)}$
$\frac{10.4}{Sin(B)} =12.73922$
$10.4 =12.73922115(sinB)$
$sinB= 0.816276439$
(take the inverse sine to get the measure of ∠B)
∠B= 60.8040992°


Answer:
The angle measures approximately 60.80°.
