Show all work. Calculate and find the x-intercepts of the
following function:
f(x)=x^2+5x-36

Answers

Answer 1
We can do this by factoring: x^2 + 5x - 36, which is (x+9)(x-4)
We plug f(x) as 0, so (x+9)(x-4)=0, so x = -9 and x = 4
The x-intercepts are (-9, 0) and (4, 0).

The Great Pyramids of Giza, Egypt are dedicated the following pharaohs EXCEPT ___________.
a. Khafre
b. Tutankhamen
c. Khufu
d. Menkaure,

Answers

The Great Pyramids of Giza are dedicated to Khafre, Khufu, and Menkaure. Tutankhamen did not have a pyramid dedicated to him and the tomb he was buried in was even smaller than was typical by that point in Egyptian history for someone of his social status.
Final answer:

The Great Pyramids of Giza in Egypt are dedicated to Khafre, Khufu, and Menkaure, but not Tutankhamen.

Explanation:

The Great Pyramids of Giza in Egypt are dedicated to three pharaohs - Khafre, Khufu, and Menkaure. The pharaoh that is not associated with one of the Great Pyramids is Tutankhamen. Tutankhamen, also known as King Tut, ruled during the 18th dynasty of the New Kingdom but was not part of the Fourth Dynasty that built the pyramids at Giza.

tan(x+pi/2)= negative cot x

Answers

I'm only going to alter the left hand side. The right side will stay the same the entire time

I'll use the identity tan(x) = sin(x)/cos(x) and cot(x) = cos(x)/sin(x)
I'll also use sin(x+y) = sin(x)cos(y)+cos(x)sin(y) and cos(x+y) = cos(x)cos(y)-sin(x)sin(y)

So with that in mind, this is how the steps would look:

tan(x+pi/2) = -cot x
sin(x+pi/2)/cos(x+pi/2) = -cot x
(sin(x)cos(pi/2)+cos(x)sin(pi/2))/(cos(x)cos(pi/2)-sin(x)sin(pi/2)) = -cot x
(sin(x)*0+cos(x)*1)/(cos(x)*0-sin(x)*1) = -cot x
(0+cos(x))/(-sin(x)-0) = -cot x
(cos(x))/(-sin(x)) = -cot x
-cot x = -cot x

Identity is confirmed

Lyle deposited a check for $75.26. He’ll use the check register to record his transaction. What will be his new balance?

Answers

Answer

$896.44

Explanation

Remember that to get the current balance, you subtract all the debits from balance and add all the deposits to it.

We know from our table that the first transaction is medical bill, which is debit, so we are going to subtract the medical bill from the balance to find the  balance at that point in time.

Balance = $862.74 - $41.56 = $821.18

We also know that the second transaction is a check deposit for $75.26, so to find the current balance, we just need to add $75.26 to our previous balance.

Current balance = $821.18 + $75.26 = $896.44

List the angles of triangle DEF in order from smallest to largest measure if DE = 7, EF = 9, and DF = 3.


∠D, ∠E, ∠F


∠E, ∠F, ∠D


∠F, ∠E, ∠D


∠D, ∠F, ∠E

Answers

The angles in order from smallest to largest would be ∠E, ∠F, ∠D.

∠D is opposite side EF.  ∠E is opposite side DF.  ∠F is opposite side DE.  The sides that are the smallest correspond with the smallest angles, and the sides that are the largest correspond with the largest angles.
Answer: The order from smallest to largest is <E, <F, <D

First, you should draw a picture of triangle DEF and label all of the sides. Then, you will have an idea of what the triangle looks like and the relative size of the angles.

You can also look at the side opposite of the angle. The larger the opposite side, the larger the angle.

What is measure of angle P?

Enter your answer as a decimal in the box. Round only your final answer to the nearest hundredth.

Answers

Sin P = opp/hyp
sin P = 15/17
P = sin⁻¹(15/17)
P = 61.93° (nearest hundredth)

Answer:

The measure of angle P is 61.93°

Step-by-step explanation:

We are given a right triangle with measures 8 cm, 15 cm and 17 cm.

For angle P, we see that,

Perpendicular = 15 cm

Hypotenuse = 17 cm

Using the trigonometric forms of the angles, we have,

[tex]\sin P=\frac{Perpendicular}{Hypotenuse}[/tex]

i.e. [tex]\sin P=\frac{15}{17}[/tex]

i.e. [tex]\sin P=0.88235[/tex]

i.e. [tex]P=\arcsin 0.88235[/tex]

i.e. P = 61.93°

Hence, the measure of angle P is 61.93°.

This is just a reassurance question It's
n = 75 ÷ 0.32 Right?,

Answers

32% of 75 is 24


Explanation:

32% of 75

32/100*75/1


32/100*75/1   Cancel and Simplify.



8/1*3/1

Answer = 24


2: The following equation used to solved the problem is:

(A):  N = 0.32(75)


Hope this helps.

24 is 32% of 75. The answer can be found by setting up a proportion: n/75 is set equal to 32/100, where x represents 32% of 75. By using cross multiplying and solving for the variable "n" we can determine that n = 24. Therefore, the equation n = 0.32(75) could be used to determine the correct answer. The formula n = 75 ÷ 0.32 is incorrect.

answer
5 units
Final answer:

The value of x can signify diverse number based on the context it is applied in. For instance, it can be a certain range of values, part of a chemical equation, or the result of a mathematical equation. Therefore, the value of x is determined by the given conditions.

Explanation:

The value of x can be discovered through various mathematical processes depending on the context. In the examples given, x was used to denote different values across multiple scenarios.

One situation presented x as a value that ranged from 1.5 to 4.5, indicated by 1.5 ≤ x ≤ 4.5. In another instance, x was determined by the concentration of hydroxide ions in a chemical equation, which resulted in x = 4.0 × 10-³ M. Furthermore, x was also inferred from a quadratic equation where it implied the hydronium concentration.

In summary, the value of x varies based on the mathematical or scientific context it is applied to, and its value must be determined through specified conditions or equations.

What is the measure of ∠DQM?

Answer:

Hello! I just completed the quiz :))

Step-by-step explanation:

This is for more confirmation (´。• ᵕ •。`) ♡ glad I could help!

Tangent is a straight line that touches the circle at any point on the curve.  The measure of ∠DQM in ΔDQM is 40º.

What is a tangent?

A tangent is a straight line that touches the circle at any point on the curve. And the angle made by the tangent with radius is always 90°.

We know that line AD is the tangent to circle M, and line MD is the radius of the circle, therefore, the measure of ∠ADM is 90°.

Now, In ΔDQM, the measure of ∠DMQ is 50º, while the measure of ∠MDQ is 90º. therefore, the sum of all the angles of the ΔDQM can be written as,

[tex]\angle DQM + \angle MDQ + \angle DMQ = 180^o\\\\\angle DQM + 90^o + 50^o = 180^o\\\\\angle DQM = 180^o -90^o -50^o\\\\\angle DQM = 40^o[/tex]

Hence,  the measure of ∠DQM is 40º.
