Answer: In 4 HOURS they will be 468 miles apart.

Step-by-step explanation:

1st car DATA:

rate = 59 mph ; time = x hrs. ; distance = 59x miles

2nd car DATA:

rate = 58 mph ; time = x hrs. ; distance = 58x miles

EQUATION:

distance + distance = 385

59x + 58x = 468

117x = 468

x = 4 hours.

Answer:

[-1, 1]

Step-by-step explanation:

The range will be all y-values that the function reaches. Here, we see that the function is periodic which goes through a pattern of waves. It will go forever in both directions of the x-axis. However, in the y-dimension, it ranges from -1 to 1. It will have brackets as it touches 1 and -1 instead of approaching.

Answer:80

Assume the number to be 400 for instance,

10% of 400 increased = 400 + ( 10/100 × 400 )

= 400 + 40 = 440

The resulting number decreased by its 10% = 400 - (10/100 × 400)

= 400 - 40 = 360

Now, net decrease = 440 - 360 = 80

Answer:

400.

10% of 400 is 40 (Simply reduce the hundreds place to the tens place)

So now we have 440.

Decrease it by 10% again, and that brings you right back to 400.

Answer:

1) In fig. (1) there are 2 shapes:

So,

Area of Rectangle = l × b

where,

➮ 12 × 14

➮ 168

Hence, the area of rectangle is 168cm².

Now,

Area of Triangle = ½bh

where,

➮ ½ × 8 × 12

➮ ½ × 96

➮ 48

Hence, the area of triangle is 48cm².

Thus, Area of the whole fig. :

Area of Rectangle + Area of Triangle

➮ 168 + 48

➮ 216cm² (Ans)

2) In fig. (2) there are also 2 shapes :

So,

Area of Semicircle = ½ (πr²)

where,

➮ ½ × 3.14 × (5)²

➮ ½ × 3.14 × 25

➮ ½ × 78.5

➮ 39.25

Hence, the area of semicircle is 39.25 in².

Now,

Area of Rectangle = l × b

where,

➮ 10 × 15

➮ 150

Hence, the area of rectangle is 150 in².

Thus, Area of whole fig. :

Area of Semicircle + Area of Rectangle

➮ 39.25 + 150

➮ 189.25 in² (Ans)

Answer:

dz/dt = -(3x + 9y)/z

Step-by-step explanation:

x² + y² + z² = 9

2x dx/dt + 2y dy/dt + 2z dz/dt = 0

x dx/dt + y dy/dt + z dz/dt = 0

x * 3 + y * 9 + z dz/dt = 0

so

dz/dt = -(3x + 9y)/z

Answer: The length of the rectangle would be 20 inches and the width would be 14 inches.

Step-by-step explanation:

If the length is 20, first, it’s 6 more than 14, and second it would add up to 40. If the width is 14, it’s 6 less than 20, and adds up to 28. If you add those two together, you’d get your total of 68 inches for the perimeter!

Answer:

y=4x-6

Step-by-step explanation:

That is how you would graph it.

Hope this helps!

The first step is to find any two sets of points on the line to find the slope. Let's use (0, -6) and (4,10).

   [tex]Slope=\frac{y2-y1}{x2-x1} =\frac{10--6}{4-0} =\frac{16}{4} =4[/tex]

Ok, now we found the slope. Now let's put it into the point-slope form which requires any one point on the line and the slope. Lets use the point (0,-6)  

        [tex](y-y0)=m(x-x0)\\(y+6)=4(x-0)\\y=4x-6[/tex]

The last equation is the slope-intercept form.

Hope that helped!

Answer:

1/3

Step-by-step explanation:

There is one input being mapped into two different outputs, so this is not a function. The correct option is D.

A function is a relation that maps elements from one set (the domain) into elements from another set (the range). Such that each element from the domain can be mapped into only one element from the range.

In this case, the table is:

So, the input "12" appears twice, the first time is mapped into 300 miles, and the second time is mapped into 350.

So the same value from the domain is being mapped into two different values of the range, meaning that this is not a function. So the correct option is D.

Problem 3

A triangle cannot be constructed with these parameters.

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

Explanation:

Use the Law of Sines to find angle B

sin(A)/a = sin(B)/b

sin(120)/12 = sin(B)/13

sin(B) = 13*sin(120)/12

sin(B) = 0.93819419

B = arcsin(0.93819419) or B = 180 - arcsin(0.93819419)

B = 69.75047247 or B = 180 - 69.75047247

B = 69.75047247 or B = 110.24952753

These angle values are approximate.

-----------

If B = 69.75047247, then,

A+B+C = 180

C = 180 - (A+B)

C = 180 - (120 + 69.75047247)

C = -9.75047247000001

We get a negative result which isn't valid.

This means B = 69.75047247 isn't valid either.

-----------

If B = 110.24952753, then,

A+B+C = 180

C = 180 - (A+B)

C = 180 - (120 + 110.24952753)

C = -50.24952753

We get a similar conclusion here as well.

-----------

No matter what value of B we go with, we end up with a negative value for angle C.

Negative angles are not allowed.

Therefore, we cannot construct a triangle with sides a = 12, b = 13 and angleA = 120 degrees.

This is one example of an SSA triangle leading to no possible solutions. Refer to the SSA ambiguous case for more info.

-----------

Check out the diagram below. Imagine that point B can be anywhere on the dotted circle. Imagine it can rotate around as in an animation. This circle is centered at point C and has radius a = 12. No matter where point B is placed, we cannot get it to land on the horizontal line to therefore form a triangle. Simply put: side a = 12 is too short.

I used GeoGebra to make the diagram and make sure it's to scale. This is to visually verify that we cannot construct such a triangle with these parameters.
