what are the solutions of the equation 6x^2+x-2= 0

The inequality that represents the situation is [5x + 9y ≤ 35] where x and y are the number of t-shirts and shorts purchased.

An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way.

The majority of the time, size comparisons between two numbers on the number line are made.

So, we know that:

The T-shirts cost $5.

The shorts cost $9.

The total budget is $35.

Then, the inequality can be:

5x + 9y ≤ 35

Where x and y are the number of t-shirts and shorts purchased.

5(3) + 9(2) ≤ 35

15 + 18 ≤ 35

33 < 35

Therefore, the inequality that represents the situation is [5x + 9y ≤ 35] where x and y are the number of t-shirts and shorts purchased.

An algebraic equation of the second degree in x is a quadratic equation. Ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term, is the standard quadratic equation.

y = -16a² + 190x + 72

for maximum y value we need to find y'(x)

y' = -32x + 190

put y' = 0

-32x + 190 = 0

x = 5.94 sec

so after 5.94 sec it will reach at maximum height.

Answer:

h = 30

Step-by-step explanation:

This problem is asking us to solve for h.

If you divide, multiply, subtract both sides of a equation by the same number, the  final result will stay the same.

1) Divide 7 on both sides.

[tex]\frac{7(h-22)}{7} =\frac{56}{7}[/tex]

2) Simplify.

h-22 = 8

3) Add 2 on both sides.

h - 22 + 22 = 8 + 22

4) Simplify.

h = 30

Recall that the degree of the polynomial is the highest power of the variable.

The degree of the given polynomial function is 3.

we know that a cubic function is a polynomial function with degree 3.

Hence the given function is a cubic function.

Option D is correct.

We can solve the problem by using the probability binomial distribution model. The formula is:

Recall that:

Given:

number of samples(n) = 8

x = 3

8% of all major bridges in that city will have ratings of 4 or below implying that the probability of a bridge having a rating of 4 or below is 0.08.

Hence,

The probability that in a random sample of 8 major bridges in the city, at least 3 will have an inspection rating of 4 or below in 2020 would be:

Probability of at most 2 can be reduced to:

x = -0.6

The equation that represents this scenario is:

0.7x + 0.1*3 = 0.4(x + 3)

Solving for x, we have:

0.7x + 0.3 = 0.4x + 0.12

0.7x - 0.4x = 0.12 - 0.3

0.3x = -0.18

x = -0.18/0.3

Answer: -2

Step-by-step explanation:

To find the slope of a line, we use the formula [tex]\frac{y(2)-y(1)}{x(2)-x(1)}[/tex]

{x(2),y(2)} coordinates of second points in line

{x(1),y(1)} coordinates of first points in line

So to solve, you take any set of your coordinates given and you chose one to be your second set and your first set. Then you take the y from your 1st set, and you subtract it from the y from your 2nd set. Then you take that and you put it over from what you get when you take the x from the 1st set, and you subtract that from the x in your 2nd set.

So when I solve using this the coordinates given, I get -12-8/17-7

This equals to -20/10, and that equals to -2.
So you find the slope of the line as -2

The area of the sector of the circle is about 0.3 dm².

A circle is a two-dimensional figure made up of points that are spaced out from a fixed point (center) on the plane by a fixed or constant distance (radius).

Given that, the radius of the circle is r = 0.5 dm and the angle of the sector is v = 135°

The sector area of the circle is given by:

A = (v/360°) × πr²

Substitute the values:

A = (135°/360°) × (3.14)(0.5)²

A = 0.375 × 3.14 ×0.25

A = 0.3

Hence, the area of the sector of the circle is about 0.3 dm².

Answer:

24 ft by 15 ft

Step-by-step explanation:

Let l be the length of the garden. Then

l - 9 is the width of the garden.

[tex]l(l - 9) = 360[/tex]

[tex] {l}^{2} - 9l = 360[/tex]

[tex] {l}^{2} - 9l - 360 = 0[/tex]

[tex](l - 24)(l + 15) = 0[/tex]

Best friend ----> +$12

-$93

Babysitting Saves +$20/week

We are still needing $93 dollars to buy the pen, so, if she earns $20 peer week, then she should work:

$93 = 20 $/week * number of weeks

Calling x to the number of weeks and turning this into an inequality:

12 + 20x ≥ 105

Subtracting -12 to both sides:

20x ≥ 105-12

Simplifying:

20x ≥ 93

Dividing both sides by 20:

x ≥ 93/20

Simplifying:

x ≥ 4.65

The cost of 1 pound of orange will be $1.5. The total payment was $15. The total weight of orange was 10 pounds.

The unitary method is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value. A single or distinct unit is referred to by the word unitary. Therefore, the goal of this method is to establish values in relation to a single unit. The unitary method, for instance, can be used to calculate how many kilometers a car will travel on one litre of gas if it travels 44 km on two litres of fuel. The unitary method involves calculating the value of a single unit, from which we can calculate the values of the necessary number of units.

Here,

cost of 2 pound of orange=$3

cost of 5 pound of orange=$7.50

cost of 3 pound of orange=$4.50

Therefore,

The cost of 1 pound of orange is $1.5

The total payment made=$7.50+$4.50+$3

=$15

The total weight of oranges=2+3+5

=10 pounds

One pound of oranges will cost $1.5. $15 was paid in total. Orange weighed ten pounds in total.

Applying the Pythagoras Theorem, the length of RS = 8 units.

According to the figure,

Diameter = 16 +4 = 20 units

So, the Radius = Diameter/2 = 20/2 = 10 units

Now,

Let the center be M, then

MT = 10 - 4 = 6 units

RT = x units

The radius is perpendicular to the chord,

So, MTR will be a right-angled triangle,

We will apply the Pythagoras theorem,

So, we have :

[tex]RT^{2} +TM^{2} =RM^{2}[/tex]

Here, RT = x units

TM = 6 units and RM = radius = 10 units

Putting these values in the Pythagoras theorem,

[tex]x^{2} +6^{2} =10^{2}\\x^{2} + 36 = 100 \\x^{2} = 100 - 36 = 64\\x^{2} = 64 \\x = 8[/tex]

1100 children and 1900 adults attended the local zoo on that day.

A system of equations or an equation system is a finite set of equations for which common solutions are sought.

Given:

A local zoo's admission fee is $1.50 for children and $4.00 for adults.

On a certain day, 3000 people enter the zoo and $9250.00 is collected.

We have to determine how many children and how many adults attended?

Solution:

Let number of children enter the zoo = x

Then number of adults enter the zoo = 3000-x

Total collection =  $9250

Collection from children + Collection from adults = 9250

1.50 × x + 4(3000-x) = 9250

1.5x + 12000 – 4x = 9250

1.5x - 4x  = 9250 - 12000

-2.5x = -2750

2.5x = 2750

X =2750/2.5

X = 1100

Number of children enter the zoo = x = 1100

Number of adults enter the zoo = 3000 - x = 3000 - 1100 = 1900

Therefore 1100 children and 1900 adults attended the local zoo on that day.
