Answer:

  (D)  -1.3 + 1.9

Step-by-step explanation:

The number being subtracted in the given expression is -1.9. The opposite of that number is +1.9.

If we are to show equivalence of subtraction and adding the opposite, we expect to do so with ...

  [tex]-1.3-(-1.9)=\boxed{-1.3+1.9}[/tex]

This is not a choice that is presented in this problem statement, so we suppose it is D (not shown).

Answer:

Its not possible to solve without the actual table.

Step-by-step explanation:

The ball is lower than the bridge at the interval [2, 3.385] and (-∞,0) contains negative values

The equation of the function is given as

h(t)= -16t^2 + 32t + 75

The above equation is a quadratic equation

When the balloon is less than the bridge i.e. a height of 75 feet, we have

h(t) < 75

So, we have the following equation and inequality

h(t)= -16t^2 + 32t + 7

h(t) < 75

Next, we plot the equation and inequality on a graph (see attachment)

The equations intersect at

t = 0 and t = 2

Remove when t = 0

t = 2

The ball hits the ground at t = 3.385

So, the interval is [2, 3.385]

Also, (-∞,0) is not included in the solution because time cannot be negative

The 10th term of this arithmetic sequence 100,110,120,130...​ is 190.

An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference

d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.

In a geometric sequence numbers are written in the same constant ratio(r).

It means every next number is a multiple of a common constant and the previous number.

r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.

Given, An arithmetic sequence 100,110,120,130...​

First term a₁ = 100, Common difference(d) = 130 - 120 = 120 - 110 = 10.

We know nth term of an arithmetic sequence is aₙ = a₁ + (n - 1)×d.

aₙ = 100 + (n - 1).10.

aₙ= 100 + 10n - 10.

aₙ = 10n + 90

So, the 10th term a₁₀ = 100 + (10 - 1).10 = 100 + 90 = 190.

I can't see anything it is full black

Answer:

The value of x is 6

Step-by-step explanation:

The formula of the area of the rectangle is A = l × w, where

In the rectangle ABCD

∵ AB = 2x cm

∴ l = 2x

∵ AD = x cm

∴ w = x

→ Use the formula of the area above to find its area

∵ A = 2x × x

∴ A = 2x²

∵ The area of the shaded region = 50 cm²

→ When the shaded region removed, then the remaining area is the

   unshaded region

∵ The area of unshaded region = 22 cm²

∵ The area the ABCD = area the shaded region + area unshaded region

∴ A = 50 + 22

∴ A = 72 cm²

→ Equate the two right side of A

∵ 2x² = 72

→ Divide both sides by 2

∴ x² = 36

→ Take √  for both sides

∴ x = 6

∴ The value of x is 6

Answer:

5 guests

Step-by-step explanation:

Jeremiah party will chat $16 if he invites 4 guest

The first step is to calculate how much it will cost to feed one guest

$4 = 16 guests

1 guest= 16/4

1 guest = $4

Therefore if Jeremiah can afford to spend $20 then the maximum number of people that will be present can be calculated as

$4 = 1 guest

$20= 20/4

= 5 guests

Hence the maximum number of guest is 5 guests

Answer:

x=55

Step-by-step explanation:

Answer:

Domain is all real numbers.

Range is -3 to infinity that is y >= -3 (that is y -3)

Increasing from x > -4 ( that is from -4 to +infinity) that is to right of -4

Decreasing from x <-4 (that is -infinity to -4) that is to left of -4

This has a minima at x= -4 with y= -3. We can write as (-4, -3)

Maxima is not there as it is going to infinity

3 Answers: x = 0, x = 1, or x = 2

==================================================

Explanation:

The relation

{(0, 5) (1, 5) (2, 6) (x, 7)}

has points with x coordinates of: 0, 1, 2, and x.

If we repeated any of the x values listed so far, then we will not have a function.

So if we had the points (0,5) and (0,7), then the input x = 0 leads to multiple outputs. A function is only possible when any input x leads to exactly one output y.

This means that if x = 0, 1, or 2, then we won't have a function.

Side note: The y values can repeat, but if they do, then we won't have a one-to-one function. In this case, y = 5 repeats, so this function is not one-to-one (assuming x is not 0, not 1, and not 2).

Answer:

Exponential Functions

In linear functions, rate of change is constant: as x goes up, y will go up a consistent amount. In exponential functions, the rate of change increases by a consistent multiplier—it will never be the same, but there will be a pattern.

Answer:

15 dozens of cakes

Step-by-step explanation:

It is given that Jeanna is making cupcakes for her family and she normally makes 2 dozens of red velvet cakes and 3 dozens of gingerbread spice cakes. But as everybody is staying at home, Jeanna wants to increase the standard amount by 3 for enough cakes.

So,

2 dozens of velvet cakes, i.e.

2 x 12 = 24 red velvet cakes

Increasing this amount by 3 times will give us 24 x 3 = 72 red velvet cakes.

Similarly,

3 dozens of gingerbread spice cakes, i.e.

3 x 12 = 36 gingerbread spice cakes

Increasing this amount by 3 times will give us 36 x 3 = 108 gingerbread spice cakes.

Therefore the total number of cakes is = 72 + 108

                                                                 = 180 cakes.

We know 1 dozen = 12

Therefore dividing 180 cakes by 12, we get

[tex]$=\frac{180}{12}$[/tex]

= 15 dozen cakes.

Therefore, now Jeanna will have to make 15 dozens of cupcakes for all.
