There are five position players on a starting basketball team: 2 guards, 2 forwards, 1 canter. Write a ratio in simplest from to express each relationship
Final answer:
The ratios for the basketball positions in simplest form are guards as 2:5, forwards as 2:5, and the center as 1:5.
Explanation:
The question asks to write ratios for the positions on a basketball team and then to express those ratios in simplest form. There are 5 position players on a starting basketball team, consisting of 2 guards, 2 forwards, and 1 center. To express the relationships between each position, we can write the ratios of guards to the total number of players, forwards to the total number of players, and the center to the total number of players.
The ratio of guards to the total number of players is 2 guards to 5 total players, which simplifies to 2:5.
The ratio of forwards to the total number of players is 2 forwards to 5 total players, simplifying to 2:5.
Lastly, the ratio of the center to the total number of players is 1 center to 5 total players, simplified as 1:5.
A boy throws a baseball across a field. The ball reaches its maximum height, 18 meters, after 1 second. After approximately 2.3 seconds, the ball lands on the ground. The ball’s motion can be modeled using the function f(x) = –10x2 + 20x + 8. What is the height of the ball 1.5 seconds after it is thrown?
Answer:
Step-by-step explanation:
Alright, lets get started.
The function that models the height of the ball is given by :
[tex]f(x)=-10x^2+20x+8[/tex]
When we plug x as 1.5 , we could get the height f(1.5) as :
[tex]f(1.5)=-10(1.5)^2 +20*1.5 +8[/tex]
[tex]f(1.5)=-22.5+30+8[/tex]
[tex]f(1.5)=15.5[/tex]
So the height of the ball after 1.5 second is 15.5 meters. : Answer

What are the solutions to x2 8x 7 = 0? x = –8 and x = –7 x = –7 and x = –1 x = 1 and x = 7 x = 7 and x = 8?
The correct solutions to the given equation are x = 1 and x = 7.
The solutions to the equation x² - 8x + 7 = 0 are x = 1 and x = 7.
To find these solutions, we can factor the quadratic equation by finding two numbers that multiply to 7 (the constant term) and add up to -8 (the coefficient of the x term).
Therefore, the correct solutions to the given equation are x = 1 and x = 7.

If f(x)=x^2-3x,find f(-1.8). Show all work
The value of f(x) = x²-3x at x = -1.8 is -2.16.
What is a quadratic function?A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.
We have the quadratic function:
f(x) = x²-3x
So, to find the value at x = -1.8:
Substitute the value to the function.
f(-1.8) = (-1.8)²-3(-1.8)
f(-1.8) = 3.24 - 5.4
f(-1.8) = -2.16
Therefore, the value is -2.16.

while on vacation, your family budgeted $550 for food. Your family went to the grocery store for drinks and snacks and spent $67.19 Each meal you are going to eat out had a budget of $55
Which expression describes the amount of money left in your after you consume your meals ?
A. 550 - (67.19 + 55x)
B.550- x(67.19 -55)
C.550-x(67.19+55)
D.550-(67.19-55x)
Final answer:
The correct expression to calculate the remaining budget for food after spending on groceries and meals out is 550 - (67.19 + 55x), which is option A.
Explanation:
The question asks us to determine which expression correctly represents the amount of money left in the budget for food after the family has spent money on groceries and consumed their meals. The original budget for food is $550, and the family spent $67.19 on drinks and snacks. Each meal they plan to eat out is budgeted at $55. Let's denote the number of meals the family will eat out as 'x'.
To calculate the remaining budget after these expenses, we subtract the cost of groceries and the total cost of eating out (which is $55 times the number of meals 'x'), from the original budget for food. The correct mathematical expression for the remaining budget is:
550 - (67.19 + 55x)
This expression is represented by option A. This correctly factors in the initial expenditure on groceries of $67.19 and then subtracts $55 for each meal 'x' from the remaining budget.

a customer brings in a item for refund.The price on the item is $4.80 and the tax is 5%.How much including tax should the cashier refund back to the customer
Answer:
The cashier should refund back to the customer $5,04
Step-by-step explanation:
The cashier has to refund the amount the customer paid, which was the price plus the proportional tax.
Refund=price+tax
Price=$4.80
Tax=$4.80 * 0,05= $0,24
Refund=$4.80 +$0,24=$5,04
What is the multiplicative rate of change of the exponential function shown on the graph?
A) 2/9
B) 1
C) 4
D) 9/2
Answer:
Option: D is correct.
9/2
Step-by-step explanation:
We have to find the multiplicative rate of change of the exponential function shown on the graph.
We know that a general exponential function is given as:
[tex]y=ab^x[/tex]
where b is the multiplicative rate of change.
Now when x=0 we have y=1.
i.e. 1=a
Hence, a=1
and y=b^x
Also,
the graph passes through (1,9/2)
Now when x=1 we have y=9/2
i.e.
9/2=b
Hence, the multiplicative rate of change is:
9/2
The correct answer is A) 2/9. The multiplicative rate of change of the exponential function shown on the graph is A) 2/9.
To determine the multiplicative rate of change of an exponential function from its graph, we need to identify two points on the graph that are one unit apart horizontally (i.e., one unit apart in the x-direction). The multiplicative rate of change is the ratio of the function values (y-values) of these two points.
Let's assume we have two points, (x, y) and (x+1, y'), where y and y' are the corresponding y-values of the exponential function at these x-values. The multiplicative rate of change, r, is given by:
[tex]\[ r = \frac{y'}{y} \][/tex]
From the graph, we can identify two such points. For example, if the function passes through the y-axis at (0, 1) and then at (1, 2/9), we can calculate the multiplicative rate of change as follows:
[tex]\[ r = \frac{2/9}{1} = \frac{2}{9} \][/tex]
This is the multiplicative rate of change of the exponential function. It indicates that for every unit increase in x, the y-value is multiplied by 2/9.
Therefore, the multiplicative rate of change of the exponential function shown on the graph is A) 2/9.
