The next model of a sports car will cost 12.2% less than the current model. The current model costs $34,000 . How much will the price decrease in dollars? What will be the price of the next model?
Answer:
Price decrease in dollars = $4,148Price of next model = $29,852Step-by-step explanation:
The next car will be 12.2% cheaper. This amount in dollars is:
= Percentage decrease * Current model price
= 12.2% * 34,000
= $4,148
The price of the next model will therefore be:
= 34,000 - 4,148
= $29,852
The diagram shows a right-angled triangle.

15 cm
Find the size of angle x.
Give your answer correct to 1 decimal place.
Answer:
x ≈ 31.0°
Step-by-step explanation:
From the right triangle given in the picture,
By applying tangent rule,
tan(x) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(x) = [tex]\frac{9}{15}[/tex]
x = [tex]\text{tan}^{-1}(\frac{9}{15} )[/tex]
x = [tex]\text{tan}^{-1}(0.6)[/tex]
x = 30.96
x ≈ 31.0°
Therefore, measure of angle x is 30.0°
Find the value of x using the corresponding angles theorem.

a= 29 and b = 4
O a= 61 and b = 16
O a= 4 and b = 58
none of these
Please please
Answer:
first option
Step-by-step explanation:
In a parallelogram consecutive angle are supplementary, sum to 180, so
2a + 122 = 180 ( subtract 122 from both sides )
2a = 58 ( divide both sides by 2 )
a = 29
---------------
In a parallelogram the opposite sides are congruent, then
b + 6 = 10 ( subtract 6 from both sides )
b = 4

Answer:
x = -3±√31 ≈ {-8.568, +2.568}
Step-by-step explanation:
The usual steps are to ...
group the x-terms
(x² +6x) -22 = 0
add and subtract the square of half the x-coefficient
(x² +6x +(6/2)²) -22 -(6/2)² = 0
simplify to a binomial square
(x +3)² -31 = 0
Solve for x.
(x +3)² = 31
x +3 = ±√31
x = -3 ±√31 . . . . . solution to the quadratic

Step-by-step explanation:

The quotient of 9x³ - 21x² + 12x divided by 3x is 3x² - 7x + 4.
What is a factor of a polynomial?We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.
To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.
Given, A cubic polynomial 9x³ - 21x² + 12x and being divided by 3x.
So, (9x³ - 21x² + 12x)/(3x).
= 9x³/3x - 21x²/3x + 12x/3x.
= 3x² - 7x + 4.
So, The quotient when 9x³ - 21x² + 12x and being divided by 3x is
3x² - 7x + 4.

find the equation of the parabola that has... stretched by factor of 3
Answer:

Step-by-step explanation:
Slope intercept form
Given:
The equation of the parallel line is
[tex]y=-\dfrac{5}{2}x+7[/tex]
The required line passes through the point (-4,1).
To find:
The equation of line in slope slope intercept form.
Solution:
The slope intercept form of a linear function is
[tex]y=mx+b[/tex]
Where m is slope and b is y-intercept.
On comparing the equation [tex]y=-\dfrac{5}{2}x+7[/tex] with slope intercept form, we get
[tex]m=-\dfrac{5}{2}[/tex]
We know that the slopes of parallel lines are always same. So, the slope of the required line is [tex]m=-\dfrac{5}{2}[/tex].
The line passes through the point (-4,1) with slope [tex]m=-\dfrac{5}{2}[/tex]. So, the equation of line is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-(1)=-\dfrac{5}{2}(x-(-4))[/tex]
[tex]y-1=-\dfrac{5}{2}(x+4)[/tex]
[tex]y-1=-\dfrac{5}{2}x-10[/tex]
Adding 1 on both sides, we get
[tex]y=-\dfrac{5}{2}x-10+1[/tex]
[tex]y=-\dfrac{5}{2}x-9[/tex]
Therefore, the correct option is C.
find the direction angel of this vector <-5, 9>
Answer:
θ = -60.94°
Step-by-step explanation:
The given vector is:
v = -5i+9j
We need to find the angle of this vector.
The angle of this vector form is given by :
[tex]\tan\theta=\dfrac{y}{x}\\\\\tan\theta=\dfrac{9}{-5}\\\\\tan\theta=-1.8\\\\\theta=\tan^{-1}(-1.8)\\\\=-60.94^{\circ}[/tex]
So, the angle of this vector is -60.94°.
A line passes through the point (-6,9) and has a slope of -5/2 . Write an equation in point-slope form for this line.
Answer:
y-9=-5/2(x+6)
Step-by-step explanation:
y-y1=m(x-x1)
y-9=-5/2(x-(-6))
y-9=-5/2(x+6)
An equation in point-slope form for this line would be y-9=-5/2(x+6).
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) has gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
Which is the required equation of a line in a point-slope form.
Thus,
y-y1= m(x-x1)
A line passes through the point (-6,9) and has a slope of -5/2 So,
y-9=-5/2(x-(-6))
y-9=-5/2(x+6)
Hence, an equation in point-slope form for this line would be y-9=-5/2(x+6).
