Find twe positive even consecutive intecers such
that the square of the smaller integer is 10 more
than the larger integer.
Answer:
The numbers are 4 and 6
Step-by-step explanation:
Let:
x - the smaller even consecutive integer x+2 - the larger even consecutive integerwe know that
[tex]x^{2} =(x+2)+10[/tex]
solve for x
[tex]x^{2} -x-12=0[/tex]
We can use the quadratic formula for quadratics in the form [tex]ax^{2} +bx+c=0[/tex]
[tex]x= \frac{-b(+/-)\sqrt{b^{2} -4ac}}{2a}[/tex]
to give us an answer of 4 and -3
Since the question states positive and even we use 4 and that gives us 6 as the other answer
4 and 6
Answer:
4 and 6
Step-by-step explanation:
x = smaller integer
x+2 = larger integer
x² = 10 + (x + 2)
x² = x + 12
x² - x - 12 = 0
factors are:
(x-4)(x+3) = 0
x-4=0; x = 4
x+3=0; x = -3
Since the question states the numbers are even and positive we use only the 4 and the next consecutive even integer is 6

Emir is standing in a treehouse and looking down at a swingset in the yard next door. The angle of depression from Emir's eyeline to the swing set is 31. 43°, and Emir is 11 feet from the ground. How many feet is the base of the tree from the swingset? Round your answer to the nearest foot. 15 feet 20 feet 18 feet 24 feet.
Tangent is the ratio of perpendicular to the base. The distance between the base of the tree and the swing set is 18 feet.
What is Tangent(Tanθ)?The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm{Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
Base is the adjacent smaller side of the angle θ.
As it is given that the height of the tree is 11 feet, while the angle of depression is 31.43°, therefore, the tangent can be written as,
[tex]\rm{Tangent(31.43^o) = \dfrac{AB}{BC}[/tex]
Where BC is the length between the base of the tree and the AB is the height of the tree.
[tex]\rm Tangent(31.43^o) = \dfrac{11}{BC}\\\\BC = 17.999 \approx 18[/tex]
Hence, the distance between the base of the tree and the swing set is 18 feet.

Answer:
(x, y) = (-6, -10)
Step-by-step explanation:
Pick a variable whose coefficient you want to be zero in the sum. Note the two coefficients of that variable in the two equations. Write the second coefficient in the first box, and the opposite of the first coefficient in the second box.
__
If you want to eliminate x-terms, the x-coefficients are -2 and -3. Write -3 in the first box and +2 in the second box.
-3(-2x +2y = -8) ⇒ 6x -6y = 24
+2(-3x +y = 8) ⇒ -6x +2y = 16
Added together, the resulting equation is ...
0x -4y = 40
y = -10 . . . . . . . divide by -4
__
If you want to eliminate y-terms, the y-coefficients are 2 and 1. Write 1 in the first box, and -2 in the second box.
1(-2x +2y = -8) ⇒ -2x +2y = -8
-2(-3x +y = 8) ⇒ 6x -2y = -16
Added together, the resulting equation is ...
4x +0y = -24
x = -6 . . . . . . . . divide by 4
__
Now, you know the solution is (x, y) = (-6, -10).
_____
Additional comment
It does not matter which is the first equation. You can swap the two equations and still achieve the desired results. Also, if the coefficients have a common factor, you can divide that out. As you may have noticed, the arithmetic is a little easier if one of the chosen coefficients is 1 or -1.
If you're combining the equations using addition, as we have done here, then one of the coefficient multipliers must be negated, as we have described. If you're combining the equations using subtraction, then you can preserve the original signs of the coefficients (or change them both).

What is the equation of the line that passes through the point (-2, 1) and has a
slope of -5/2?
Answer:
y = -5/2x - 4
Step-by-step explanation:
When given a point and a slope, we use slope-intercept formula:
y - y1 = m (x - x1)
m = slope point: (-2,1)
y - y1 = m (x - x1)
y - 1 = -5/2 (x - (-2))
y -1 = -5/2x - 5
+ 1 + 1
y = -5/2x - 4

Answer:
CD = 3 -√3
Step-by-step explanation:
The ratio of leg lengths in a 30°-60°-90° triangle is ...
1 : √3 : 2
The longest leg of ΔABD is 2√3, so we must multiply all of these ratio values by √3 to see the actual lengths of the triangle sides.
AB : BD : AD = 1 : √3 : 2 = √3 : 3 : 2√3
That is ...
AB = √3
BD = 3
__
The lengths of the legs in isosceles right triangle ABC are the same, so ...
BC = AB = √3
Then the length of interest is ...
CD = BD -BC
CD = 3 -√3 . . . . . . . a=3, b=-1
Circle the equation with a rate of change of 3.
y=3x+12
3y=2x+5
Y=6x-3
(Please explain how you got your answer)
Answer:
[tex]y = 3x + 12[/tex]
Step-by-step explanation:
The rate of change is represented as the slope.
The problem is asking for a slope that is equal to 3.
y=6x-3 is incorrect, the equation is simplified and the slope is 6.
3y=2x+5 is incorrect, the slope is 2 and the equation isn't simplified.
y=3x+12 is correct, the equation is simplified and it's showing the correct slope.
Find a polynomial that represents the area of the square.
Answer:
49x²+126x+81
Step-by-step explanation:
Area of any square is length²
If the length given is 7x+9, we can square this to find out what represents the area:
[tex](7x+9)^{2}[/tex]
[tex](7x+9)(7x+9)[/tex]
[tex]49x^{2} +63x+63x+81[/tex]
[tex]49x^{2} +126x+81[/tex]
Answer:
49x² + 126x + 81
Step-by-step explanation:
A = a²
Since a = 7x + 9
=> A = (7x+9)²
= 49x² + 126x + 81
Note: (a+b)² = a² + 2ab + b²

Answer: Intercept Form
Step-by-step explanation:
There are three methods for determining the minimum value of a quadratic equation. Each of them can be useful in determining the minimum. The first way is by using a graph. You can find the minimum value visually by graphing the equation and finding the minimum point on the graph. The y-value of the vertex of the graph will be the minimum. This is especially easy when you have a graphing calculator that can do most of the work for you.
Write the point slope form of the equation of the line through the given points: (-4,-1) and (-3,1)
PLEASE EXPLAIN. STEP BY STEP INSTRUCTIONS
Step-by-step explanation:
the general point-slope form is
y - y1 = m(x - x1)
with (x1, y1) being a point on the line, and m being the slope (the incline of the line).
we have the point. we can pick one from the 2 choices, I typical go for the one with smaller values. so, I will use (-3, 1).
now we need to calculate the slope.
the slope is the ratio "y coordinate change / x coordinate change" when going from one point on the line to another.
so, for our 2 points we see
x changes by +1 (from -4 to -3).
y changes by +2 (from -1 to +1).
and the slope is +2/+1 = 2
therefore our equation is
y - 1 = 2(x - -3)
or simplified
y - 1 = 2(x + 3)

Brian borrowed $22,000 to buy a car. The rate of interest was 9.5% and the length of time was 5 years. What will be Brian's total cost for his car?
Answer:
Compound interest
$34633.25
Step-by-step explanation:
Everything starts of at 100% and the rate of interest is 9.5% so we add them on=109.5%
Now we want this percentage as a decimal so we divide by 100 = 1.095 this our multiplier
Then get the original amount that you borrowed = 6000 times by the multipler=1.095 to the power of number of years so
6000 multipled by 1.095 to the power of 5
Giving me $34633.25
