For triangle ABC, find the measure of AB given me∠ A = 55 degrees, m∠b= 44 degrees, and b=6. . A. 45.22. B.96.68. C.88.19. .

jekas [21]

There exist a similar question where b = 68 instead of 6. First, determine the measure of the third angle, angle C,
m∠c = 180 - (55° + 44°) = 81°
Let x be the side AB, that which is opposite to angle C. Through the Sine Law,
68 / sin 44° = x / sin 81°
From the equation, the value of x is equal to 96.68. Thus, the answer is letter B.

A bike rental stand at the beach charges $5 to rent a bike in targit charges to every half hour it is rented if someone pays $17

denis23 [38]

Answer:

They would have the bike for 1.7 hours

Step-by-step explanation:

The bike is rented at a charge of $5 for every half an hour,this can be expressed as:

$5 per 0.5 hours, to calculate the time one will have the bike if they pay $17

The amount of paid=Standard Rate per 1/2 of an hour/Number of hours

where;

The amount paid=$17

Standard Rate per 1/2 an hour=$5/0.5

Number of hours

Replacing;

n=(17×0.5)/5=1.7 hours

Find the minimum y-value on the graph of y=f(x)<br><br> F(x) = 7x^2 + 7 - 6

Kisachek [45]

Answer:

The minimum y-value is

$y=-\frac{31}{4}$ or $y=-7.75$

Step-by-step explanation:

we have

$f(x)=7x^{2}+7x-6$

This is the equation of a vertical parabola open up

The vertex is the minimum y-value on the graph

Convert the equation into vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$f(x)+6=7x^{2}+7x$

Factor the leading coefficient

$f(x)+6=7(x^{2}+x)$

Complete the square. Remember to balance the equation by adding the same constants to each side

$f(x)+6+1.75=7(x^{2}+x+0.25)$

$f(x)+7.75=7(x^{2}+x+0.25)$

Rewrite as perfect squares

$f(x)+7.75=7(x+0.5)^{2}$

$f(x)=7(x+0.5)^{2}-7.75$ ------> equation in vertex form

The vertex is the point (-0.5,-7.75)

therefore

The minimum is the point (-0.5,-7.75)

The minimum y-value is $y=-7.75=-7\frac{3}{4}=-\frac{31}{4}$

see the attached figure to better understand the problem
