Answer:
m = -3
Step-by-step explanation:
−m − 19 = 8m + 8 (Simplify equation)
−9m − 19 = 8 (Subtract 8m from both sides)
−9m = 27 (Add 19 to both sides)
m = -3 (Divide both sides by -9)

Answer:
68.9°
Step-by-step explanation:
Using Sine rule
x/sin X = y/sin Y
4.5/sin X = 4/sin 56
sin X × 4 = 4.5 × sin 56
sin X = 4.5 × sin 56/4
X = arc sin (4.5 × sin 56/4)
X = 68.85449°
Approximately = 68.9°
the number of squirrels in a park at the end of the month
Using the given recursive function, we have that:
a) There will be 132 squirrels in the park at the end of August.
b) As time goes by, the number of squirrels in the park will increase.
What is the recursive function for this problem?
The recursive function for this problem models the number of squirrels in the park at the end of month n+1, considering the amount present at the end of month n, as follows:
[tex]S_{n+1} = 1.6S_n - 30[/tex]
For this problem, we have that at the amount at the end of May is of 70, hence:
[tex]S_{5} = 70[/tex]
Hence, we find the amounts at the end of June, July and August, as follows:
[tex]S_6 = 1.6(70) - 30 = 82[/tex].[tex]S_7 = 1.6(82) - 30 = 101[/tex].[tex]S_8 = 1.6(101) - 30 = 132[/tex].Hence:
a) There will be 132 squirrels in the park at the end of August.
b) As time goes by, the number of squirrels in the park will increase.

Answer:
[tex]E(x) = 99[/tex]
Step-by-step explanation:
Given
The attached table
Required
Number of times 3 or 4 will occur
First, we complete the table as follows:
[tex]P(1) + P(2) +......+P(6) =1[/tex]
[tex]0.13 + 0.05 + P(3) + 0.21 + 0.19 + 0.3 = 1[/tex]
Collect Like Terms
[tex]P(3)= 1 -(0.13 + 0.05 + 0.21 + 0.19 + 0.3 )[/tex]
[tex]P(3)= 0.12[/tex]
The expected number of times is:
[tex]E(x)= n * P(x)[/tex]
So, we have:
[tex]E(x) = 300 * (0.12 + 0.21)[/tex]
[tex]E(x) = 300 * (0.33)[/tex]
[tex]E(x) = 99[/tex]

A liquid starts at a temperature of 210 degrees and cools in a room held at a constant 68 degrees. After 8 minutes of cooling, it is at a temperature of 97 degrees. The temperature, F, can be modeled as a function of time in minutes by the equation
F(t) = a(b)^t + c
In ABC, b = 68 inches, B=65° and C=93º. Find the length of a, to the nearest
inches
Answer:
28inches
Step-by-step explanation:
∠A + ∠B + ∠C = 180°
∠A + 65° +93° = 180°
∠A + 158° = 180°
∠A= 180°-158° = 22°
Using Law of Sines
a/sinA= b/sinB
a/sin22= 68 inches/sin65
a/sin22 = 68/0.9063 = 75.03
a = 75.03 x sin 22
a = 75.03 x 0.3746 = 28.106238≈28 inches
You have 84 feet of streamers. You cut 24 pieces that are each 1/2 yard long. How many feet of streamers do you have left?
Answer:
48
Step-by-step explanation:
If we have 84 feet of streamers. You cut 24 pieces that are each 1/2 yard long then 48 feet of streamers we left.
What is Unit of Measurement ?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
Given that we have a 84 feet of streamers.
You cut 24 pieces that are each 1/2 yard long.
Need to find the feet of streamers we left.
We know that 1 yard is equal to 3 feet.
Therefore, 1/2 yard is equal to 1.5 feet.
The total length of the streamers that were cut is:
24 pieces x 1.5 feet/piece = 36 feet
To find out how much streamer is left, we can subtract the length of the cut streamers from the total length we started with:
84 feet - 36 feet = 48 feet
Therefore, you have 48 feet of streamers left.

The line l is tangent to the circle with equation x² + y2 = 169 at the point P.
By thinking about the radius or otherwise, determine the gradient of the line l.
Given:
The equation of a circle is
[tex]x^2+y^2=169[/tex]
A tangent line l to the circle touches the circle at point P(12,5).
To find:
The gradient of the line l.
Solution:
Slope formula: If a line passes through two points, then the slope of the line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Endpoints of the radius are O(0,0) and P(12,5). So, the slope of radius is
[tex]m_1=\dfrac{5-0}{12-0}[/tex]
[tex]m_1=\dfrac{5}{12}[/tex]
We know that, the radius of a circle is always perpendicular to the tangent at the point of tangency.
Product of slopes of two perpendicular lines is always -1.
Let the slope of tangent line l is m. Then, the product of slopes of line l and radius is -1.
[tex]m\times m_1=-1[/tex]
[tex]m\times \dfrac{5}{12}=-1[/tex]
[tex]m=-\dfrac{12}{5}[/tex]
Therefore, the gradient or slope of the tangent line l is [tex]-\dfrac{12}{5}[/tex] .

The ratio of sixth-grade students to fifth-grade students in the Kirkpatrick Elementary school band is 5:4. If there are 20 fifth-grade students in the band how many sixth-grade students are in the band?
Answer: 25 sixth graders
Step-by-step explanation:
Sixth-graders are in a ratio with fifth graders in the band at 5:4 and there are 20 fifth-grade students in the band.
To find the number of 6th graders, use direct proportion and assume the sixth grader number is x:
5 : 4
x : 20
4x = 100
x = 100 / 4
x = 25 sixth graders
The volume of a rectangular prism can be found by multiplying the three side lengths. A bookcase in the shape of a rectangular prism has dimensions (b+8) ft, b ft, and (b+3) ft. Find the volume of the bookcase
Answer:
(b³+11b²+24)ft³
Step-by-step explanation:
Volume of the rectangular prism = Length * Width * Height
Given the dimension
Length = b+8 ft
Width = b ft
Height = (b+3)ft
Volume of the rectangular prism = b(b+8)(b+3)
Volume of the rectangular prism = b(b^2+3b+8b+24)
Volume of the rectangular prism = b(b^2+11b+24)
Volume of the rectangular prism = b(b^2)+b(11b)+1(24)
Volume of the rectangular prism = b^3+11b^2+24
Hence the Volume of the rectangular prism is (b³+11b²+24)ft³

Can you answer plz
у = х + 3
у =-2x-3
Answer:
x = - 2, y = 1
Step-by-step explanation:
Comparing both the equations,
→ y = y → x + 3 = - 2x - 3
=> x + 3 = - 2x - 3
=> x + 2x = - 3 - 3
=> 3x = - 6
=> x = - 6/3 = - 2
Substitute the value of x in any of these:
=> y = x + 3 = - 2 + 3 = 1
Answer:
Step-by-step explanation:
If a solution exists for the system of equations y=y so we can say
x+3=-2x-3 Add 2x to each side
3x+3=-3 Subtract 3 from each side
3x=-6. Divide each side by 3
x=-2, since y=x+3
y=-2+3
y=1
So the solution to the system of equations is the point (x,y)=(-2,1)
