Answer:
x=4.8
Step-by-step explanation:
6=1.25x
=
x=4.8
Given the function:
f(x)=-x^2-5x+50
the zeros of the function will be obtained by factorizing the expression.
f(x)=-x^2-5x+50
f(x)=-(x^2+5x-50)
f(x)=-(x-5)(x+10)
the zeros are:
x=-10
x=5
hence taking the positive value for distance, we take x=5.
This represents the horizontal distance the diver jumped. Thus the correct answer is:
<span>x = 5; the diver hits the water 5 feet away horizontally from the board

Answer: Answer is in the steps read carefully.
Step-by-step explanation:
does not represent a rational number because the square root of 6 is not a perfect square.
This represents a rational number because the square root of 64 is a perfect square which is 8 and if added to a fraction you will get a rational number.
represents a rational number because they are both a perfect square. The square root of 16 is 4 and the square root of 169 is 13.
represents a rational number because since 17.43 repeating can be expressed as a fraction, and the square root of 49 is a perfect square, if added together they will generate a rational number.
Does not represents a rational number because the square root of 44 is not a perfect square and when you add an irrational number and an rational number then you will get an irrational number.
Exact form: x=7/6
Decimal form: x=1.16
Mixed number form: x=1 1/6
The March sales of Jazz records is an illustration of proportions, and the number of jazz records sold all year is 7x
<h3>How to determine the total number of sales?</h3>
The sales in March is given as:
Proportion = 1/7
Let the actual number of sales in the month of March be x, and the total sales in the year be y.
So, we have:
1/7 * y = x
Make y the subject
y =7x
Hence, the number of jazz records sold all year is 7x
