Find the unknown angle x.​

Answer: Hi! Here we're trying to find the unit rate.

So we know that the truck travels 238 miles in 3.5 hours. To find the unit rate, the speed of miles per hour, all we need to do is divide the miles by the total time!

238 ÷ 3.5 = 68

So, the truck travels at 68mph.

Hope this helps!

Answer: Hi!

Remember, when you're subtracting a negative, that's equal to adding a positive. So -2-(-17) is actually equal to -2 + 17!

-2 + 17 = 15

The expression -2-(-17) is equal to 15.

Hope this helps!

Answer:

Step-by-step explanation:

By MVT,

[tex]f'(c) = \frac{f(5)-f(-1)}{5-1}[/tex]

[tex]4f'(c)= f(5) + 3\rightarrow f(5) = 4f'(c) - 3[/tex]

Moreover, [tex]f'(x)\leq 4~~~~~~ \forall x,[/tex]

[tex]f(5) \leq 16 - 3 =13[/tex]

Hence the largest possible value of f(5) is 13

Answer:

h(7) = 3

Step-by-step explanation:

h(x) = -[tex]\sqrt{x-3}[/tex] + 5

h(7) = -[tex]\sqrt{(7)-3}[/tex] + 5

h(7) = -√4 + 5

h(7) = -2 + 5

h(7) = 3

Answer:

(x, y) ⟶ (−x, −y); A′ is at (5, −1)

Step-by-step explanation:

When you rotate a point 180° about the origin, it travels along the circumference of a circle and ends up in a diagonally opposite location.

The x and y values of its coordinates become the negatives of the original values.

The rule is

(x,y) ⟶ (-x,-y)

If the coordinates of A are (-5,1),

The coordinates of A' are (5,-1).

The figure below shows the graph or your rectangle and its rotated image.

Answer:

(x, y) ⟶ (−x, −y); A′ is at (5, −1)

just took the FLVS test and got a 100% :)

4-c=-1/3

3[4-c]= -1

12-3c= -1

12+1=3c

13=3c

c=13/3

c=4 1/3

Answer:

w=15

Step-by-step explanation:

w/5=3

multiply by 5 on both sides

w=3*5

∴ w=15

Answer:

15

Step-by-step explanation:

If something over 5 is 3, that means w divided by 5 equals 3.

That can bve translated to W=3 times 5, which is 15.

Therefore, W= 15.

Answer:

Take the information given and create an equation that add up to 360.

Step-by-step explanation:

You might assume the smallest angle to be the given 55, so that would make the third term 120+55. The fourth angle is unknown, x

The equation sets up as

55+65+(55+120)+x = 360

Add all the numbers to get 295.

295+x=360

Subtract 360-295 = x

x=65

The four angles are 55°,65°,175° and 65°

Answer:

d=√ 82=9.1

Step-by-step explanation:

The quadratic formula is:

[tex]y = ax^{2} + bx + c[/tex]

To complete the square, take half of the b coefficient and square it. Zero it out in the equation by adding and subtracting it. Use the order of operations (PEMDAS) and solve for x.

I hope this helps. Let me know if you want me to clarify anything or if you have any questions!

The solution of the given quadratic equation is x = -1 ±√2

Suppose that we've a function y = f(x) such that f(x) is quadratic.

When y = 0, then the values of x for which f(x) = 0 is called the solution of quadratic equation f(x) = 0. This solution gives values of x, also when we plot x and f(x), we will see that the graph intersects the x-axis at its solution points.

The quadratic formula is given as;

x² + 2x =1

Then its solutions are given as;

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

[tex]x = \dfrac{-2 \pm \sqrt{2^2 - 4(-1)}}{2}\\\\x = \dfrac{-2 \pm \sqrt{4 + 4}}{2}\\\\\\x = \dfrac{-2 \pm \sqrt{8}}{2}\\\\x = \dfrac{-2 \pm 2\sqrt{2}}{2}\\\\\\x = \dfrac{-1 \pm 1\sqrt{2}}{1}[/tex]

Therefore, the solution is x = -1 ±√2

Answer:

[tex]\huge\boxed{Option \ B}[/tex]

Step-by-step explanation:

1) 3 + 2 = 5       [Since the result is a natural number, it is a rational number]

2) [tex]\sqrt{19} + \frac{7}{2}[/tex]    [ It has a square root that cannot be simplified further so the sum of this is an irrational one ]

Answer:

[tex]\Huge \boxed{\sqrt{19} +7}[/tex]

Step-by-step explanation:

Rational numbers can be integers, fractions, and whole numbers.

Rational numbers can be expressed as fractions p/q, where p and q are whole numbers.

[tex]3+2=5[/tex]

5 is whole number, it is a rational number.

[tex]\sqrt{19} +7= 11.358899....[/tex]

[tex]\sqrt{19}[/tex] is an irrational number, it cannot be expressed as a fraction p/q, where p and q are whole numbers.

[tex]\displaystyle \frac{18}{3} +\frac{11}{10000} =\frac{60011}{10000}[/tex]

The result is rational, it can be expressed as a fraction p/q, where p and q are whole numbers.

Answer:

120ft/sec

Step-by-step explanation:

Assuming that there is no acceleration, divide the amount of feet (720) with the time (6 seconds):

720 ft/6 sec = 120 ft/1 sec

For every second, the skydiver drops 120 ft.

120ft/sec.

Answer:

The side length of the square region is about 181,166 kilometres.

Step-by-step explanation:

population density = no. of people / area of region

given

population = 200,000

population density = 1650 people per square kilometers

1650 = 200,000/area of region

=> area of region = 1650*200,000 = 330,000,000

given that region is square in shape

area of square = side^2

side^2 =  330,000,000

side = [tex]\sqrt{ 330,000,000} = 181165,90[/tex]

The side length of the square region is about 181,166 kilometres.
