The missing length of the triangle be 7.93725.

The Pythagorean Theorem states that the squares on the hypotenuse (the side across from the right angle) of a right triangle, or, in standard algebraic notation, \($c^2=a^2+b^2$$\), are equal to the total of the squares on the legs.

Remember that in every right triangle, the area of the square with the hypotenuse side is equal to the sum of the areas of the squares with the two legs side (the two sides that meet at a right angle).

With the aid of the Pythagorean Theorem, we may determine the side lengths of a right triangle by adding the areas of three intersecting squares.

By using Pythagorean Theorem is:

\($c^2=a^2+b^2$$\)

where c exists the hypotenuse and a and b exists the sides.

\($\sqrt{\left(12^2-9^2\right)}=7.93725$$\)

Therefore, the correct answer is 7.93725.

Answer:

The equivalent function of \(sin\left(180^{\circ }+x\right)\) will be: \(-\sin \left(x\right)\)

i.e.

\(\sin \left(180^{\circ \:}+x\right)=-\sin \left(x\right)\)

Step-by-step explanation:

Considering the function

\(sin\left(180^{\circ }+x\right)\)

Solving

\(sin\left(180^{\circ }+x\right)\)

Using the angle sum identity:

\(\sin \left(s+t\right)=\sin \left(s\right)\cos \left(t\right)+\cos \left(s\right)\sin \left(t\right)\)

\(=\sin \left(180^{\circ \:}\right)\cos \left(x\right)+\cos \left(180^{\circ \:}\right)\sin \left(x\right)\)

as

\(\cos \left(180^{\circ \:}\right)=\left(-1\right)\)

\(\sin \left(180^{\circ \:}\right)=0\)

so

\(=0\cdot \:\cos \:\left(x\right)+\left(-1\right)\cdot \:\sin \:\left(x\right)\)

\(=0\cdot \cos \left(x\right)-1\cdot \sin \left(x\right)\)

\(=0-1\cdot \sin \left(x\right)\)

\(=0-\sin \left(x\right)\)

\(=-\sin \left(x\right)\)

So, the equivalent function of \(sin\left(180^{\circ }+x\right)\) will be: \(-\sin \left(x\right)\)

Therefore:

\(\sin \left(180^{\circ \:}+x\right)=-\sin \left(x\right)\)

Step-by-step explanation:

4x + 2x - 10 = 6x - 12

6x - 10 = 6x - 12

-10 ≠ -12

no solutions

The number of solution will be;

⇒ No solution.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 4x + 2 (x - 5) = 3 (2x - 4)

Now,

Since, The expression is,

⇒ 4x + 2 (x - 5) = 3 (2x - 4)

Solve for x as;

⇒ 4x + 2x - 10 = 6x - 12

⇒ 6x - 10 = 6x - 12

⇒ - 10 = - 12

⇒ - 10 ≠ - 12

Thus, It has No solution.

Since the computed value of f from the data (1.86) is not greater than the critical value of 9.487, we fail to reject the null hypothesis. There is not enough evidence to support the alternative hypothesis.

In hypothesis testing, the critical region represents the range of values that would lead to the rejection of the null hypothesis. In this case, the critical region is defined as f > 9.487.

To perform the test, we compare the computed value of f from the data (1.86) with the critical value. Since 1.86 is not greater than 9.487, it falls outside the critical region.

When the computed value of the test statistic falls outside the critical region, we fail to reject the null hypothesis. This means that the data does not provide enough evidence to support the alternative hypothesis. In other words, there is not sufficient evidence to conclude that the observed effect is statistically significant.

Answer:

Measure the angle in degrees of the first angle and then replicate the same angle with the same measurements on the other side of the yard.

Step-by-step explanation:

The reasoning isn't correct.

It should be noted that the fruit salsa recipe calls for 2 cups finely chopped pineapple and 4 cups of finely chopped strawberries

This implies that the ratio is:

= 2/4

= 1/2

= 1:2.

Therefore when Isaiah only has 1 cup of pineapple, the appropriate strawberry will be:

Answer:

1) 1.96

2) 6

3) 4/3

Step-by-step explanation:

think of exponents as repeated multiplication. the exponent is how many times you're going to multiply the number itself by.

1) \(1.4^{2}\) is really just 1.4 * 1.4, which you can solve by long multiplication or a calculator to get 1.96

2) for this one, you can rewrite the expression as a fraction. you'll also want to use PEMDAS, starting with the parentheses

\(\frac{300}{ 2(0.5+4.5)^{2}}\\\\\frac{300}{2*(5)^2}\\\\\frac{300}{2*25} \\\\\frac{300}{50} = 6\)

3) \((\frac{1}{2})^{3} = \frac{1}{2} *\frac{1}{2} *\frac{1}{2} = \frac{1}{8} \\\)

you can rewrite the division as a fraction again, only this time. you can change the subtraction to the reciprocal of the denominator

\(\frac{1}{3} / (2*\frac{1}{8} )= \frac{1}{3} / \frac{1}{4} = \frac{1}{3} * 4 = \frac{4}{3}\)

Answer:

The point crosses over the y-axis

Step-by-step explanation:

Given

A change in the sign of x coordinate

Required

The effect on the point location

Assume the coordinate to be (x,y).

The above point is located in the first quadrant,

When the x value changes to negative i.e. (-x,y)

The point moves from the first quadrant to the second quadrant

This implies that, the point crosses over the y-axis.

Similarly, assume the coordinate to be (-x,-y).

The above point is located in the third quadrant,

When the x value changes i.e. (x,-y)

The point moves from the first quadrant to the fourth quadrant

This implies that, the point crosses over the y-axis.

With the given budget, you can buy 12 movie tickets and 3 restaurant gift cards.

As the person in charge of buying prizes for the game night, your goal is to purchase at least 12 prizes while spending less than $150.

Movie tickets cost $8.50 each, and restaurant gift cards cost $15 each.

To determine how many of each prize you can buy, let's start by considering the cost of movie tickets.

If you buy 12 movie tickets at $8.50 each, the total cost would be 12 * $8.50 = $102.

Next, let's see how many restaurant gift cards you can buy.

Subtracting the cost of the movie tickets from the total budget of $150 gives us $150 - $102 = $48 remaining.

Since each gift card costs $15, you can buy $48 / $15 = 3 gift cards.

Now, let's summarize what you can buy with the given budget.

You can purchase 12 movie tickets at a cost of $102 and 3 restaurant gift cards at a cost of $45.

In total, this would be $102 + $45 = $147.

To double-check, we can verify that the total cost of the prizes is less than $150, which it is.

So, with the given budget, you can buy 12 movie tickets and 3 restaurant gift cards.

Answer: The probability is 50%.

Step-by-step explanation: The probability that both are girls if the older child is a girl can be calculated through probability. First, we know that there are two genders the child can be, male or female. When we have 2 possible outcomes, the probability of each outcome is 50%. We know the first child is a girl, and that the second child has a 50% chance of being a girl, so the probability is 50%.
