The question said we should write a compound inequality of the given graph.
We are also asked to use x as the variable.
From the graph, we can see that both end values are shaded dots, which means x is inclusive of those two values.
Since:
x ≥ -5
and
x ≤ 6
Therefore, the compound inequality of the given graph is:
-5 ≤ x ≤ 6.
What are the values of w and x in the triangle below? Round the answers to the nearest tenth.thank you ! :)
Answer:
w = 14.4
x = 11.2
Explanation:
We would consider the smaller and larger right angle triangles.
For the smaller right triangle, taking 48 as the reference angle,
opposite side = 16
adjacent side = w
We would find w by applying the tangent trigonometric ratio which is expressed as
tanθ = opposite side/adjacent side
Thus,
tan48 = 16/w
By cross multiplying,
wtan48 = 16
w = 16/tan48
w = 14.4
For the larger right triangle, taking 32 as the reference angle,
opposite side = 16
adjacent side = w + x = 14.4 + x
We would find w by applying the tangent trigonometric ratio which is expressed as
tanθ = opposite side/adjacent side
Thus,
tan32 = 16/(14.4 + x)
By cross multiplying,
(14.4 + x)tan32 = 16
(14.4 + x) = 16/tan32
14.4 + x = 25.6
x = 25.6 - 14.4
x = 11.2
Consider the following graph. List the ordered pairs corresponding to the points in the graph?
Answer:
A(-6, 1)
B(-6, -7)
C(7, -9)
D(-8, -8)
Explanation:
From the graph, we can see that at point A, x = -6 and y = 1. Therefore, the ordered pair can be written as A(-6, 1)
At point B, x = -6 and y = -7. The ordered pair can be written as B(-6, -7)
At point C, x = 7 and y = -9. Its ordered pair will be C(7, -9)
At point D, x = -8 and y = -8. Its ordered pair will be D(-8, -8)
11) Tell whether (3, 20) is a solution of y = 4x +8 A) Yes B) No
y = 4x + 8
To tell if (3, 20) is a solution, we will substitute the value of x = 3 and y= 20
into the equation to see if the left-hand side equals the right-hand side of the equation
So, upon substituting
20 = 4 x 3 + 8
20 = 12 + 8
20 = 20
Since the left-hand side of the equa

Question 4Task 2: Nee how (hello)Business is projected to be booming after the latest release of The Fast and the Furious3.14159265359... Carver's Auto Custom must determine how many cans of paint and rims tostock at their Shanghai location.The Carver Family did choose Warehouse Space A. The warehouse includes 8000 sq. ft. ofshowroom and workshop space. One half of this warehouse space will be used to stock paintcans and rims. The warehouse has a height of 20 ft.Tell how many of cans you will stock. You must have exactly 4 cans ofpaints for every rim you stock.
The area of the warehouse is
[tex]A=8000ft^2[/tex]Half of this area stock paint, cans and rims:
[tex]\begin{gathered} A_{\text{stock}}=4000ft^2 \\ \text{then, the volume of the room is} \\ V_{\text{stock}}=4000\times20 \\ V_{\text{stock}}=80000ft^3 \end{gathered}[/tex]thats because the heigth of the stock room is equal to 20 ft.
On the other hand, we know that there are 2 cans in a box which volume
[tex]\begin{gathered} V_{\text{box}}=15\times7\times6inches^3 \\ \text{then for one can, the volume is} \\ V_{\text{can}}=\frac{V_{box}}{2}=\frac{15\times7\times6}{2}=15\times7\times3inches^3 \\ V_{\text{can}}=315in^3 \end{gathered}[/tex]and a rim is inside a box with measures
[tex]\begin{gathered} V_{\text{rim box}}=36\times36\times15inches^3 \\ V_{\text{rim box}}=19440in^3 \end{gathered}[/tex]Then, we need to find the ratio V_total to V_stock in order to find the number of rims in the room.
Then, V_total is the sum of 4 times the volume of one can plus the volume of 1 rim, that is,
[tex]V_{\text{total}}=4\cdot V_{\text{can}}+V_{\text{rim}}[/tex]because we need 4 cans and 1 rim in our room. This total volume is given by
[tex]V_{\text{total}}=4\cdot315+19440inches^3[/tex]which gives
[tex]V_{\text{total}}=20700inches^3[/tex]The last step is convert the V_total from cubic inches to cubic feets. We can do that by means of
[tex]V_{\text{total}}=20700inches^3(\frac{1ft^3}{12^3inches^3})[/tex]because 1 feet is equal to 12 inches. It yields,
[tex]\begin{gathered} V_{\text{total}}=20700(\frac{1}{144}) \\ V_{\text{total}}=143.75ft^3 \end{gathered}[/tex]Finally, we can find the ratio mentioned above:
[tex]\text{ratio}=\frac{V_{stock}}{V_{total}}=\frac{80000}{143.75}=556.52[/tex]By rounding down to the nearest interger, the ratio is 556. This means that we can stock 556 rims in the warehouse.

Which graph shows point pas (-5,6)and point q as (3,-4)?
Answer
Option A is correct.
From the explanation, we can easily see that the first graph shows point P as (-5, 6) and Point Q as (3, -4).
Explanation
The key to marking points on the graph is to know that the coordinates are named as (x, y)
And to mark a point (-5, 6), it means x = -5 and y = 6
So, we move 5 units to the left from the origin along the negative x-axis and 6 units upwards along the y-axis.
And for (3, -4), x = 3, y = -4
We move 3 units to the right from the origin along the positive x-axis and 4 units downwards along the y-axis.

ANSWER
8/12. Option C
EXPLANATION
In a simple term: Equivalent fraction can be determined by simply multiplying the numerator and the denominator by the SAME NUMBER.
That is,
if you have 2/3 the equivalent fraction will be 4/6 (when multiplied by 2) or 6/9 (when multiplied by 3) or 8/12 (when multiplied by 4) etc.
So, from the question above:
The equivalent fraction of 4/6 (when multiplied by 2) is 8/12

We have the following problem:
Using the kinematic equation, we know that for movements with constant acceleration the position is
[tex]h(t)=h_0+v_0t-\frac{gt^2}{2}[/tex]I already wrote the variables convenient for our problem, where
t = time (s)
h₀= initial height (m)
v₀ = initial velocity (m/s)
g = gravity acceleration (m/s²)
h = height after t seconds
We also know that
t = independent variable
h₀= 10m
v₀ = 56 m/s
g ≅ 10 m/s²
h = dependent variable
Therefore our quadratic will be
[tex]\begin{gathered} h(t)=10+56t-\frac{10t^2}{2} \\ \\ h(t)=10+56t-5t^2 \end{gathered}[/tex]Now we can answer the question in fact.
a)
The rocket will hit the ground when the height is equal to zero, hence, h(t) = 0. In fact, we are looking for the zeros of the quadratic
[tex]\begin{gathered} 10+56t-5t^2=0 \\ \\ t=\frac{-56\pm\sqrt{56^2-4\cdot(-5)\cdot(10)}}{2\cdot(-5)} \\ \\ t=\frac{-56\pm\sqrt{3136+200}}{-10} \\ \\ t=\frac{56\pm\sqrt{3336}}{10} \\ \\ t=11.38\text{ s or }-0.18\text{ s} \end{gathered}[/tex]See that we have one negative zero, but we will ignore that because it's physically impossible, therefore the rocker will reach the ground after 11.38 seconds
b)
To find the maximum height we must find the max value of the quadratic, we know that the vertex of a quadratic is its max/min, also, we can write it as
[tex]\begin{gathered} y_V=-\frac{\Delta}{4a} \\ \\ x_V=-\frac{b}{2a} \end{gathered}[/tex]Where
[tex](x_V,y_V)[/tex]Is the vertex. Here, we want to find the y coordinate, because y here is the height, therefore
[tex]\begin{gathered} \max h=-\frac{\Delta}{4a} \\ \\ \operatorname{\max}h=-\frac{3336}{4\cdot(-5)} \\ \\ \operatorname{\max}h=\frac{3336}{20} \\ \\ \operatorname{\max}h=166.8\text{ m} \end{gathered}[/tex]The max height of the rocket is 166.8m
c)
Now we have a similar problem, it's also the vertex but now the coordinate x, that here, represents the time, then
[tex]\begin{gathered} t_{\max}=\frac{-b}{2a} \\ \\ t_{\operatorname{\max}}=\frac{-56}{2\cdot(-5)} \\ \\ t_{\operatorname{\max}}=\frac{56}{10} \\ \\ t_{\operatorname{\max}}=5.6\text{ s} \end{gathered}[/tex]The rocket will reach the maximum height after 5.6 seconds.

Surface area = 222 square cm
Explanation:
Given the following data
Length = 3 cm
Height = 9 cm
Width = 7 cm
Surface area = 2(wl + hl + hw)
Surface area = 2(7 * 3 + 9 * 3 + 9 * 7)
Surface area = 2( 21 + 27 + 63)
Surface area = 2( 111)
Surface area = 222 square cm
