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:

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.

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.

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:

j=45 k=83 L=52

Step-by-step explanation:

j=x-7

k=2x-21

L=x

x-7+2x-21+x=180

4x-28=180

4x=208

x=52

The measure of the angles are; J = 48, K = 57 and L = 75

Linear pair of angles are produced when two lines intersect each other at a point. The sum of angles of the linear pair is always 180 degrees.

In order to determine the measure of these angles, we have to set J as x. then find the measure of all of these angles.

J = x

K = x + 9

L = 2x - 21

Now, we can add them all together and set equal to 180;

x + x + 9 + 2x - 21 = 180

4x - 12 = 180

4x = 192

x = 48

Now that we have;

J = x = 48

K = x + 9 = 48 + 9 = 57

L = 2x - 21 = 2(48) - 21 = 96 - 21

L = 75

Hence, The measure of the angles are; J = 48, K = 57 and L = 75

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.

Now;

We know that;

Area of circle (a) = π*(r^2)

= 3.14*(7^2)

= 3.14*49

= 153.86 cm^2

Therefore, the area of a circle is 153.86 cm^2.

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:

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:

The bus driver drives 30 miles in 5 days.

Step-by-step explanation:

Hi,  

You can use the rule of three to solve this problem.

For the first step, we need to analyze the information given:

[tex]6 (miles) = 1 (day)[/tex]  

and we want to know how much miles the bus driver drives in 5 days:

[tex]x (miles) = 5 (day)[/tex]

Thus,

[tex]6 (miles) = 1 (day)[/tex]   ... (1)

[tex]x (miles) = 5 (day)[/tex]   ... (2)

Now, multiplying in a cross and  we have:

[tex]x *1 = 5*6 \\ x = 30[/tex]

Lastly, replacing the value of x in (2):

[tex]30 (miles) = 5 (day)[/tex]

and this is the answer
