Answer:
x=11
Step-by-step explanation:
you need to get x by itself so just add it to the other side and you get x=11
Answer:
x =11
Step-by-step explanation:
x - 3 = 8
To solve the equation, we have to isolate 'x'.
To isolate 'x', we have to add 3 to both sides.
x - 3 + 3 = 8 + 3
x = 11
Marco created a table to help him represent the sample space of spinning a spinner and flipping a coin. Result of spin Result of coin toss Red Green Yellow Heads Red, heads Green, heads Yellow, heads Tails Red, tails Green, tails Yellow, tails What is the probability that the result of the spin is green and the coin lands tails up? one over six two over six three over six four over six.
The probability that the result is green - tail is 1/6.
Spinner has three colors that are red, green and yellow and coin has two sides that are head or tail.
What is the formula for probability?Divide the number of events by the number of possible outcomes
The sample space is,[tex]{(red - head; red - tail; green - head; green - tail; yellow - head; yellow - tail)}[/tex]In total there are 6 ways to combine different colors with coin sides.
Therefore ,the probability that the result is green - tail is 1/6.

The path of a football kicked by a field goal kicker can be modeled by the equation y = –0. 04x2 1. 56x, where x is the horizontal distance in yards and y is the corresponding height in yards. What is the approximate maximum height of the football? 15. 21 yd 19. 5 yd 38. 94 yd 45. 63 yd.
The maximum height of the football is 15.21 yards.
Maximum height of parabolaThe maximum height is the vertex of the parabola, when the parabola faces down.
Given
The path of a football kicked by a field goal kicker can be modeled by the equation y = -0.04x^2 + 1.56x.
Where x is the horizontal distance in yards and y is the corresponding height in yards.
The x- coordinate of the vertex is given by;
[tex]\rm x=\dfrac{-b}{2a}[/tex]
The value of b is 1.56, and a is -0.04.
Substitute all the values in the equation
[tex]\rm x=\dfrac{-b}{2a}\\\\x=\dfrac{-1.56}{-0.08}\\\\x=19.5[/tex]
Substitute the value of x in the given equation
[tex]\rm y = -0.04x^2 + 1.56x\\\\ y = -0.04(19.5)^2+1.56(19.5)\\\\y = - 15.21 + 30.42 \\\\ y=15.21 \ yd[/tex]
Hence, the maximum height of the football is 15.21 yards.

find the area of this figure. round your answer to the nearest hundredth. use 3.14 to approximate pi
Answer:
51.63 m²
Step-by-step explanation:
[tex]\textsf{Area of a semicircle} =\dfrac12\pi r^2[/tex]
Given:
[tex]\pi =3.14[/tex][tex]\textsf{diameter}=6 \textsf{ m}\implies \textsf{radius}=3 \textsf{ m}[/tex][tex]\implies \textsf{area}=\dfrac12 \times 3.14 \times 3^2=14.13[/tex]
[tex]\textsf{Area of a triangle} =\dfrac12 \times \textsf{base} \times \textsf{height}[/tex]
Given:
base = 3 mheight = 5 m[tex]\implies \textsf{area}=\dfrac12 \times 3 \times 5=7.5[/tex]
[tex]\textsf{Area of a rectangle} =\textsf{width} \times \textsf{length}[/tex]
Given:
width = 5 mlength = 6 m[tex]\implies \textsf{area}=5 \times 6=30[/tex]
Total area = area of semicircle + area of triangle + area of rectangle
= 14.13 + 7.5 + 30
= 51.63 m²
Solution:
Step-1: Find the area of the triangle.
[tex]\text{Area of triangle} = \dfrac{1}{2} \times \text{Base} \times \text{Height}[/tex]
[tex]\text{Area of triangle} = \dfrac{1}{2} \times 3 \times 5[/tex]
[tex]\text{Area of triangle} = 3 \times 2.5[/tex]
[tex]\text{Area of triangle} = 7.5 \ \text{m}^{2}[/tex]
Step-2: Find the area of the rectangle.
[tex]\text{Area of rectangle} = \text{LB}[/tex]
[tex]\text{Area of rectangle} = (6)(5)[/tex]
[tex]\text{Area of rectangle} = 30 \ \text{m}^{2}[/tex]
Step-3: Find the radius of the semi-circle.
[tex]\text{Diameter = 2(Radius)}[/tex]
[tex]6 \ \text{m = 2(Radius)}[/tex]
[tex]\dfrac{6}{2} \ \text{m} = \dfrac{2\text{(Radius)}}{2}[/tex]
[tex]3 \ \text{m} = \text{Radius}[/tex]
Step-4: Find the area of the semi-circle.
[tex]\text{Area of semi-circle} = \dfrac{\pi r^{2} }{2}[/tex]
[tex]\text{Area of semi-circle} = \dfrac{(3.14)( 3^{2} )}{2}[/tex]
[tex]\text{Area of semi-circle} = \dfrac{(3.14)(9 )}{2}[/tex]
[tex]\text{Area of semi-circle} = (3.14)(4.5 )[/tex]
[tex]\text{Area of semi-circle} = 14.13 \ \text{m}^{2}[/tex]
Step-5: Find the area of the figure.
[tex]\text{Area of figure = Area of triangle + Area of rectangle + Area of semicircle}[/tex]
[tex]\text{Area of figure = 7.5 + 30 + 14.13}[/tex]

How do the slopes and y–intercepts of the two equations compare?.
The two equations with slope and y-intercept are compared as the lines may be intersecting, parallel, and coincident.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
Let the two equations in the form of slope and y-intercept.
[tex]\rm L_1: y = m_1x +c_1\\\\L_2: y = m_2x +c_2[/tex]
There are three cases are as follows;
Case 1 - If lines are intersecting then the slope of both equations will be different.
Case 2 - If lines are parallel then the slope of lines are same but the intercept will be different.
Case 3 - If lines are coincident their slope and the intercept will be the same.

Sam is paying off his eight-year, $15,360 loan in semiannual installments.
The loan has an interest rate of 9.58%, compounded semiannually, and a service charge of $1,294.64. Once the loan has been fully paid off.
A = $15360
r = 0.0958/2 = 0.0479
n = 8 × 2 = 16
The periodic payment is given as
[tex]\rm A = P (\dfrac{1-(1+r)^{-n}}{r})[/tex]
Where P is Periodic payment
r = rate per period
n = number of period
Then we have
[tex]\rm 15360 = P(\dfrac{1-(1+0.0479)^{-16}}{0.0479})\\\\\\ P = 1396.16[/tex]
Then Sam will pay a total of 1396.16 × 16 = $22,338.56
Interest charge = 22338.56 – 15360 = $6978.56
Total finance charge = 6978.56 + 1294.64 = $8273.20

Youre amazing!!! could you help me? 50 points!!! Write an expression that can be used to produce vector d from vector c, and explain how you determined that expression.
Answer:
Multiply vector c by the scalar -1/2.
Step-by-step explanation:
Look at vector c.
It has an x component of 4 and a y component of 4.
You can write vector c as a sum of its components using unit vectors in the x direction (i) and in the y direction (j).
c = 4i + 4j
Now look at vector d, and write it also as a sum of its x and y components.
d = -2i - 2j
Now ask yourself, what operation do I do to 4 to end up with -2?
One answer is to multiply 4 by -1/2.
d = (-1/2)c = (-1/2)(4i) + (-1/2)(4j) = -2i - 2j
That worked. By multiplying vector c by the scalar -1/2, you end up with vector d.
