Answer:

138 g of chlorine is required to produce 214 g of sodium chloride if we have 76 g of sodium.

Step-by-step explanation:

We are given:

Grams of Sodium = 76 g

Grams of Sodium Chloride = 214 g

We need to find how many grams of chlorine required to produce 214 g of sodium chloride

The equation will be:

[tex]Na \ + \ Cl \ -> NaCl\\76\ g \ \ \ x \ g \ \ \ \ \ \ \ \ 214 g[/tex]

We can write: 76 (g) + x (g)=214 (g)

Solving and finding value of x

x =214-76

x=138 g

So, 138 g of chlorine is required to produce 214 g of sodium chloride if we have 76 g of sodium.

Answer:

84.26° in the south west direction.

Step-by-step explanation:

I've attached an image showing the triangle formed by the motion of the plane and the wind.

I've depicted the plane being pushed west and the wind moving south west.

Thus, the direction of motion of the plane will be angle θ.

Using trigonometric ratios;

25/250 = cos θ

cos θ = 0.1

θ = cos^(-1) 0.1

θ = 84.26°

Thus will be in the south west direction.

Answer:

b. -2/3

Step-by-step explanation:

in addition a negative plus a negative does not equal a positive so we can already assume the answer is b but to be safe we can work this problem out in this way: 1/9 + 5/9 = 6/9 we simplify 6/9 and we get 2/3 so we slap the negative back on and boom -2/3

Answer:

Graph E, B, and D all show relations and are functions

Step-by-step explanation:

Graphs E, B, as well as D all represent functions and relations, respectively. A function in mathematics from such a set X to either a set Y allocates exactly 1 element of Y to every element of X.

A function in mathematics from such a set X to either a set Y allocates exactly 1 element of Y to every element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two changing quantities.

A planet's position, for instance, depends on time. In the past, the idea was developed with both the infinitesimal calculus toward the conclusion of the seventeenth century, and the functions that were taken into consideration were differentiable until the 19th century. Graphs E, B, as well as D all represent functions and relations, respectively.

Therefore, graphs E, B, as well as D all represent functions and relations, respectively.

Answer:

Step-by-step explanation:

Given the function f(x)=-16x^2+100x+5 to calculate how far the potato will be from the ground at any given second (x), the potato hits the ground when g(x) = 0

The function becomes'

0 =-16x^2+100x+5

-16x^2+100x+5 = 0

multiply through by minus

16x^2-100x-5 = 0

x = 100 ±√100²-4(16(-5))/2(16)

x = 100±√10000+320/32

x = 100±101.59/32

x = 100+101.59/32

x = 202.59/32

x = 6.299 secs

Hence the potato will hit the ground after 6.299secs

The time taken by potato to hit the ground is [tex]6.299[/tex] seconds.

The potato will be from the ground at any given second (x) is given by below function.

             [tex]f(x)=-16x^2+100x+5[/tex]

To find the time taken by potato to hit the ground is , equate given function to zero.

            [tex]f(x)=-16x^2+100x+5=0\\\\-16x^2+100x+5=0\\\\x=\frac{-100\pm\sqrt{(100)^{2}+4*16*5 } }{-16*2} \\\\x=\frac{-100\pm101.587 } {-32} \\\\x=6.299,x=-0.049[/tex]

Since, time can not be negative.

So that we will consider , [tex]x=6.299 s[/tex]

Hence, the time taken by potato to hit the ground is [tex]6.299[/tex] seconds.

Answer:

true

Step-by-step explanation:

The reason is that when the male and female have sex the male releases sperm into the female the sperm goes to the female egg then she gets pregnet a couple of days later. Therefore that equals reproduction.

Using translation concepts, it is found that the fourth graph(right graph of the bottom row) represents the function f(x).

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

The parent function is [tex]f(x) = \sqrt{x}[/tex], which has vertex at the origin.

The translated function in this problem is [tex]f(x) = 2\sqrt{x + 1}[/tex], which was vertically strecthed by a factor of 2 units(which does not change the vertex), and shifted left 1 unit, which means that the vertex is now at (0,-1).

Hence, the fourth graph(right graph of the bottom row) represents the function f(x).

Answer:

(-4, -1), (0, 2), (4, 5)

Step-by-step explanation:

(-4, -1): If you see the x-axis and trace -4 and -1 from the y-axis, they both lead to a point that is on the graph.

(-2, 1): The graph, at -2 on the x-axis, lies at height 0.5, so 1 is wrong.

(0, 2): At 0, the graph lies on 2.

(4, 5): At 4 on the x-axis, the graph lies at height 5.

(2, 0): The graph is already at height 3.5 when at length 2.

Answer:

The slope of a line that has a y-intercept but no x-intercept will be zero.

Step-by-step explanation:

If the line has no x-intercept, then it never intersects the x-axis, so it must be parallel to the x-axis.

If a line does not have an x-intercept, it means it would never intersect the x-axis.

Thus, it must be parallel to the x-axis, meaning its slope will be zero. It would be just a horizontal line.

For example, y=9 is the line equation that does not have an x-intercept and its slope is zero.

Therefore, the slope of a line that has a y-intercept but no x-intercept will be zero.
