Answer:
12 and 14
Step-by-step explanation:
The first number can be assigned x, the second will be assigned x+2 so that it will be even.
3(x)+5(x+2) = 106
3x+5x+10 = 106
8x = 96
x = 12
x+2 = 14
The two consecutive even numbers such that the sum of three times the smaller and five times the larger is 106 are 12 and 14, computed using the linear equation in one variable 3x + 5(x + 2) = 106.
We are given two consecutive even numbers, thus the larger number will be two more than the smaller one, as consecutive even numbers differ by two.
We assume the smaller number to be x.
Thus, the larger number = x + 2.
We have been given that three times the smaller number summed with five times the larger number results in 106.
This can be shown by the linear equation in one variable:
3x + 5(x + 2) = 106.
To find the numbers, we need to solve this linear equation in one variable as follows:
3x + 5(x + 2) = 106,
or 3x + 5x + 10 = 106 {Simplifying},
or, 8x + 10 = 106 {Simplifying},
or, 8x + 10 - 10 = 106 - 10 {Subtracting 10 from both sides of the equation},
or, 8x = 96 {Simplifying},
or, 8x/8 = 96/8 {Dividing both sides of the equation by 8},
or, x = 12 {Simplifying}.
Thus the smaller number, x = 12.
The larger number, x + 2 = 12 + 2 = 14.
Thus, the two consecutive even numbers such that the sum of three times the smaller and five times the larger is 106 are 12 and 14, computed using the linear equation in one variable 3x + 5(x + 2) = 106.

7 ÷ 15 = 0.46666666666667
Step-by-step explanation:
Answer:
0.47
Step-by-step explanation:
To turn any fraction into a decimal, we must simply divide the numerator by the denominator. 7 divided by 15 is equal to 0.466666...
If we round this number to the nearest hundredth, we get 0.47.
A particle is moving along a projectile path at an initial height of 80 feet with an initial speed of 112 feet per second. this can be represented by the function h(t) = −16t2 112t 80. what is the maximum height of the particle?
Answer:
276 feet
Step-by-step explanation:
The best way to do this is to complete the square, which puts the quadratic in vertex form. The vertex of a negative parabola, which is what this is, is the highest point of the function...the max value. The k coordinate of the vertex will tell us that highest value. To complete the square, we will first set the quadratic equal to 0, then move the constant over to the other side:
The rule for completing the square is that the leading coefficient must be a positive 1. Ours is a negative 16, so we have to factor out -16:
Now the next thing is to take half the linear term, square it, and then add it to both sides. Our linear term is 7, half of that is 7/2. Squaring 7/2 gives you 49/4. So we add 49/9 into the parenthesis on the left. However, we can't forget that there is a -16 out front there that refuses to be ignored. We have to add then (-16)(49/4) onto the right:
The purpose of this is to create a perfect square binomial that serves as the h value of the vertex (h, k). Stating that perfect square on the left and doing the addition on the right:
Now we finalize by moving the constant back over and setting it back equal to y:
The vertex is
That translates to "at 3.5 seconds the particle is at its max height of 276 feet".

Find the distance between the two points rounding to the nearest tenth (if necessary).
(-7, -8) and ( -4,0)
Answer:
approximately 8.5
Step-by-step explanation:
So you can use the distance formula: [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\[/tex] which is derived from the Pythagorean theorem because normally x2-x1 would kind of give the distance length between x2 and x1 except sometimes it would be negative which wouldn't make much sense right? but it doesn't matter because it's being squared so the value ultimately becomes positive, and the same thing goes for the y-value. the distance between x2 - x1 really represents the base and y2-y1 represents the height and then adding them together gives the hypotenuse squared which is why you take the square root over the entire thing to find the distance, since the hypotenuse is the shortest distance between two points
Now all you have to do is plug the values in to get
[tex]\sqrt{(-7 - (-4))^2 + (-8 - 0)^2}\\\sqrt{(-3)^2 + (-8)^2}\\\sqrt{9 + 64}\\\sqrt{73}\\distance \approx 8.5[/tex]

Step-by-step explanation:
Let one acute angle measure x.
The other acute angle measures 2x - 6.
The sum of the measures of the acute angles of a right triangle is 90.
x + 2x - 6 = 90

O y 1-5 ≤ y ≤-1}
O (y|1 ≤ y ≤5}
Oy|1 ≤ y ≤-1)
Answer:
B) [tex]-5\leq y\leq -1[/tex]
Step-by-step explanation:
The range is the lowest point to the highest point on the graph.
Remember this:
1. domain (x-axis) LEFT –> RIGHT
2. range BOTTOM (y-axis) –> TOP
when this equation is graphed over the domain, it limits the range to being (8,–5) and (–8,–1) and since with range you only look at the y-coordinates that means that the range is [–5,–1]

What is the Factor Theorem?The Factor Theorem states that a polynomial function with roots [tex]x_1, x_2, \codts, x_n[/tex] is given by:

a = 75/(15 x 105)

Answer: y = -2/3x+23/3
Step-by-step explanation:
Parallel is the key point here. They gave points (7,3), 7 is the x value, 3 is the y value.
Take your equation
y = -2/3x+3 and substitute the 7 for the x value and 3 for the y value.
Like this...
3 = -2/3(7)+b
3 = -14/3 +b
Add 14/3 to 3
The answer is 23/3
So y = -2/3x+ 23/3
***Don't change -2/3 because it's asking for parallel***

Ly has 3 more dime than nickels and twice as many quarters than dimes. the value of his coins is $9.60. how many of each coin does he have?
Ly has 15 dimes, 12 nickels and 30 quarters given that he has 3 more dime than nickels and twice as many quarters than dimes and the value of these coins is $9.60. This can be obtained by giving variables to each represent the number of each coin and adding the values to equate with the total value of coins.
How many of each coin does he have?Let number of dimes be y
Given that,
3 more dime than nickels ⇒ Number of nickel = y - 3
twice as many quarters than dimes ⇒ Number of quarters = 2y
Value of one dime = $ 0.1 Value of one nickel = $ 0.05Value of one quarter = $ 0.259.60 = 0.1y + 0.05(y-3) + 0.25(2y)
9.60 = 0.1y + 0.05y - 0.15 + 0.5y
9.60 = 0.1y + 0.05y - 0.15 + 0.5y
9.60 + 0.15 = 0.65y
y = 9.75/0.65 = 15
y = 15
Therefore the number of each coin,
Number of dimes = y = 15Number of nickel = y - 3 =15-3 = 12Number of quarters = 2y =2×15 =30Hence Ly has 15 dimes, 12 nickels and 30 quarters given that he has 3 more dime than nickels and twice as many quarters than dimes and the value of these coins is $9.60.

The triangular region is rotated around the X-axis. What are the name and dimensions of the solid that is created from the rotation
Answer:
coneradius 8 unitsheight 6 unitsStep-by-step explanation:
The attached image shows the figure of rotation generated by rotating a triangular shape about the x-axis.
ShapeWhen the given line is rotated about the x-axis, each point on the line traces a circle in the y-z plane. Those together will make a cone shape. The radius of the circle is the distance of the point from the x-axis.
DimensionsThe base of the cone will be the circle obtained by rotating the y-intercept about the x-axis. As above, the radius of that circular base is the y-value of the y-intercept: 8 units.
The height of the cone will be the x-value of the point where the radius is zero, at x=6.
The cone has a height of 6 units and a radius of 8 units.

The graph of a function g is shown below
Answer:

Step-by-step explanation:
Another way of representing g(x) is with the variable "y". In other words, the value of g(x) is the value on the y-axis (vertical axis).
(a) The question is asking you to give the "x" value when the line crosses y = -4. The only value which satisfies this is x = 0.
(b) When 2 is placed inside the parentheses of g(x), it is asking you to find the "y" value of the line at x = 2. The only value which satisfies this is y = -5.
