Answer:
This is because this equation equals 0 when x = -5
Step-by-step explanation:
To find this, plug the value in for x.
-1.3x - 6.5
-1.3(-5) - 6.5
6.5 - 6.5
0
The expression -1.3x - 6.5 evaluated at x=-5 equals zero, which is why it is neither positive nor negative.
To verify this let's evaluate it step by step.
Substitute x = -5 into the expression:
-1.3(-5) - 6.5
Then, multiply -1.3 by -5:
-1.3 * (-5) = 6.5
Then, subtract 6.5:
6.5 - 6.5 = 0
The expression -1.3x - 6.5 evaluated at x=-5 equals zero, which is why it is neither positive nor negative.
A plane takes off at an angle of elevation of 15° and travels in a straight line for 3,000 meters. What is the height of the plane above the ground at this instant?
Answer:
776.46 m
Step-by-step explanation:
According to the scenario it is a question of right angle triangle
To find the height of the plane above the ground we will use trigonometry identity.
sinФ = opposite / hypotenusehere Ф = 15°
opposite = height
hypotenuse = 3000m
Plug values in the formula above
sin(15) = height / 3000height = sin(15)(3000)
= 776 .46 m
(make sure your calculator is in degree mode)
Answer:
776.46 m
Step-by-step explanation:
The angle of elevation is 15 degrees which is measured from the horizontal.
The height above the ground is the opposite side of the triangle, the hypotenuse is the 3000 m and the angle of elevation is 15 degrees.
The sine ratio is the one one that ties the relationship;
Therefore;
sin 15 = x/3000
x = sin 15 × 3000
= 776.46 m

if you dig a 12 feet hole and you cover up that hole how deep is that hole
Answer:
If your definition of "Cover" is to fill it in, than there is no longer a hole.
If your definition of "Cover" is to simply "cover" the hole and not filling it, there is still a 12 feet hole.
Unless your perspective is that there is no hole simply because it was Covered.
Step-by-step explanation: Try again
the hole would be over 9000 deeper

Answer:
The answer is C because when you substituted the coordinate pairs into the equation, both sides are equal which tells you that they're a solution to the equation.
Explanation:
All you do is substitute. (x,y)
A:
Substitute
1 = 4(2) - 7
Multiply the number inside the parentheses by the outside number.
1 = 8 - 7
Subtract to get your solution.
1 = 1
Both sides equal to each other so this means that this is a solution to the equation.
B:
Substitute
9 = 4(4) - 7
Multiply the number inside the parentheses by the outside number.
9 = 16 - 7
Subtract to get your solution.
9 = 9
Both sides equal to each other so this means that this is also a solution to the equation.
D:
Both ordered pair is a solution to the equation.
Find the sum of the first 100
The terms of an arithmetic sequence are generated by adding a fixed term [tex]r[/tex] every time.
So, we start with [tex]a_1=15[/tex], and we continue with [tex]a_2=15+r[/tex], [tex]a_3=15+2r[/tex] and so on.
As you can see, the general rule is [tex]a_n = 15+(n-1)r[/tex]
With this information, we can derive [tex]r[/tex], knowing that
[tex]a_{100} = 307 = 15+99r \iff 99r = 292 \iff r = \dfrac{292}{99}[/tex]
So, the sum of the first 100 terms is
[tex][tex]\displaystyle \sum_{i=0}^{99} 15+i\dfrac{292}{99} = \displaystyle \sum_{i=0}^{99} 15 + \displaystyle \dfrac{292}{99}\sum_{i=0}^{99} i = (15\cdot 99) + \dfrac{292}{99}\dfrac{99\cdot 100}{2} = 1485 + \dfrac{490342}{99}[/tex]
Describe in words how to obtain the graph of f(t) = sin(5t + 20) − 7 from the graph of y = sin(5t).
Answer: f(t) is shifted 20 units to the left and 7 units down
Step-by-step explanation:
The general form of a sin function is: y = A sin (Bx - C) + D
A is the vertical stretch (amplitude)B is the horizontal compressionC is the horizontal shift (left or right)D is the vertical shift (up or down)y = sin (5t)
f(t) = sin (5t + 20) -7
the C-value is -20 --> shifts 20 units to the leftthe D value is -7 --> shifts 7 units downDescribe the transformation that maps the pre image A to the image A'

A group of students are planning a mural at a wall the rectangular wall has dimensions of (6x+7) by (8x+5) and they are planning the mural to be (x+4) by(2x+5) what is the area of the remaining wall after the mural has been Painted
Answer: [tex]46x^2+73x+15[/tex]
Step-by-step explanation:
The area of a rectangle can be calculated with the formula:
[tex]A=lw[/tex]
l: the length of the rectangle.
w: the width of the rectangle.
The area of the remaning wall after the mural has been painted, will be the difference of the area of the wall and the area of the mural.
Knowing that the dimensions of the wall are [tex](6x+7)[/tex] by [tex](8x+5)[/tex], its area is:
[tex]A_w=(6x+7)(8x+5)\\\\A_w=48x^2+30x+56x+35\\\\A_w=48x^2+86x+35[/tex]
As they are planning that the dimensions of the mural be [tex](x+4)[/tex] by [tex](2x+5)[/tex], its area is:
[tex]A_m=(x+4)(2x+5)\\\\A_m=2x^2+5x+8x+20\\\\A_m=2x^2+13x+20[/tex]
Then the area of the remaining wall after the mural has been painted is:
[tex]A_{(remaining)}=A_w-A_m\\\\A_{(remaining)}=48x^2+86x+35-(2x^2+13x+20)\\\\A_{(remaining)}=48x^2+86x+35-2x^2-13x-20\\\\A_{(remaining)}=46x^2+73x+15[/tex]

Write the point-slope form of the line's equation satisfying the given conditions. Then use the point-slope form of the equation to write the slope-intercept form of the equation.
Passing through (negative 2,4) and (3,4)
Answer:
y = 4
or
y - 4 = 0(x - 3)
Step-by-step explanation:
The points (-2,4) and (3,4) have the same y-value. Because of this, the slope of the line will be 0 and the line will be horizontal. This means the line will have the equation y = b where b is the y-coordinate. The equation of the line is
y = 4.
In point slope form, the equation will have m = 0.
y - 4 = 0(x -3)

Name the property illustrated.
6 + 4 + 3 = 6 + 3 + 4
Final answer:
The property illustrated in the equation is the Commutative Property of Addition. It states that the order in which numbers are added does not affect the sum.
Explanation:
The equation showcases the Commutative Property of Addition. This property asserts that altering the order of addends doesn't impact the sum. Specifically, the given equation, 6 + 4 + 3, demonstrates this property as it equals 6 + 3 + 4. In essence, rearranging the sequence of addends doesn't alter the total, underscoring the flexibility of addition. This fundamental property simplifies mathematical operations, allowing for easier manipulation and calculation of sums, regardless of the order in which numbers are combined.
The Commutative Property of Addition plays a pivotal role in arithmetic, streamlining calculations and enhancing mathematical efficiency.
Rebecca has a credit line of $6,500. She had a previous balance of $398.64 and made a payment of $250. The total of her purchases is $1,257.99. What is Rebecca's available credit?
Answer:
$5093.37
Step-by-step explanation:
To get Rebecca's available credit we need to take all of her payments and purchases and previous balance.
Previous balance = $398.64
Purchases = $1,257.99
Payment = $250
Credit Line = $6,500
Now first we add together her purchases and previous balance.
398.64 + 1,257.99
This will give us:
$1,656.63 Total deductions.
Now we subtract that to her credit line.
$6500.00 - $1656.63
$4843.37
Now we take her payment and add it to her credit line.
$4843.37 + $250
$5093.37
So Rebecca's available credit is $5093.37.

Two planes left simultaneously from the same airport and headed in the same direction towards another airport 1800 km away. The speed of one of the planes was 100 km/hour slower than the speed of the other plane, and so it arrived at its destination 36 minutes after the faster plane. Find the speeds of both planes.
Answer:
Faster plane --> 600km/hr
Slower Plane --> 500km/hr
Step-by-step explanation:
Use inequality: 1800/r = 1800/(r-100) + 3/5 and solve to get r = 600, so the plane which is r -100 is 500 km/hr.
