Solve the equation 3x^2+x-5=0

Answers

Answer 1

Answer:

Step-by-step explanation:

Use the quadratic equation, with a = 3, b = 1 and c = -5

Discriminant b^2 - 4ac is 1 - 4(3)(-5) = 61

Because the discriminant is + there are two real, unequal roots:

     

      -1 ± √61

x = ---------------

            6

Answer:

$33.81

Step-by-step explanation:

Strawberries = $2.49 Per Pound (Bought 3)

Blueberries = $3.19 Per Pound (Bought 2)

Pineapples = $4.99 Per Pound (Bought 4)

So we have to multiply each price with the number of fruits bought.

So, For Example, Strawberries: $2.49 × 3 = $7.47

After you did all three individually, add them all up.

Strawberries : $7.47

Blueberries : $6.38

Pineapple : $19.96

Total = $33.81

this year Benny is 12 years old and his mom is 48 years old what percent of his mom's age is Benny's age ​

Answers

Answer:

25%

Step-by-step explanation:

Let's set up a percent proportion:

12/x = 48/100

To solve for x, we would do:

x = (12*100)/48 = 1200/48 = 25

x = 25%

In my opinion, the easiest way to do this would be to look at this and notice that 12 * 4 =48 so that means 12 is 1/4 of 48 and 1/4 = 25%.

Which ordered pair describes a point that is located 5 units to
the right of the origin and 2 units below the x-axis?

Answers

Answer:

(5,-2)

Step-by-step explanation: the right of the origin is a positive number and below is negative there fore if you go right 5 it would be 5 and down 2 would be -2 .

The ordered pair describes a point that is located 5 units to the right of the origin and 2 units below the x-axis are (5, -2).

What is the coordinate grid?

A coordinate grid has two perpendicular lines, or axes labeled just like number lines. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis. The point where the x- and y-axis intersect is called the origin.

Given a statement for coordinates a point that is located 5 units to

the right of the origin and 2 units below the x-axis,

so the left side of the x-axis is the negative value of x and the right side of x-axis is the positive values of x.

5 units to the right, which is the coordinate of x is 5

and the upper of x-axis is the positive side of the y-axis and down of x-axis is the negative side of the y-axis,

2 units below the x-axis, which is coordinate of y is -2

point is (5, -2).

Hence the coordinates of points are (5, -2).

Suppose there is a 1.6°F drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 58.3°F​, what will be the temperature when the plane reaches an altitude of 2,000 ft​?

Answers

Answer: 55.1°F

Step-by-step explanation:

We are informed that there is a 1.6°F drop in temperature for every thousand feet that an airplane climbs into the sky, if the plane reaches an altitude of 2,000ft, the drop in temperature will be:

= 1.6° × 2

= 3.2°F

If the temperature on the ground is 58.3°F​, then the temperature when the plane reaches an altitude of 2,000 ft will be:

= 58.3°F - 3.2°F

= 55.1°F

Which parent function is represented by the graph?
5+
A. Linear parent function
A
B. Quadratic parent function
C. Absolute value parent function
D. An exponential parent function

Answers

Answer:

quadratic parent function

Step-by-step explanation:

squares cannot be negative no matter what you cannot square a number into a negative number which is why there are no negative y values because y is a function of X

The parent function is represented by the graph is an exponential parent function, the correct option is D.

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Linear function is a function whose graph is a straight line

We are given that;

The graph of function

Now,

To identify which parent function is represented by the graph, we can look at the shape and features of the graph. The graph shows a curve that starts from the lower left quadrant and rises rapidly as x increases. The graph passes through the point (0, 1) and has a horizontal asymptote at y = 0. These are the characteristics of an exponential parent function with a base greater than 1.

Therefore, the function will be an exponential parent function.
