The answer is option 3: approval ratings tended to fall as stock prices rose.
This means that when stock prices rose, the approval ratings of George Bush's presidency decreased. This can be interpreted as an indication that people were not satisfied with the performance of the stock market during the Bush presidency. This could be because the stock market was not performing as well as expected or because the people were not satisfied with the decisions made by the Bush presidency that impacted the stock market.
Whatever the reason, the negative correlation between the stock market performance and Bush's approval ratings shows that when stock prices rose, approval ratings tended to fall.

Is DEF = ABC? If so, type the reason, if not type no.
Answer:
Yes
Step-by-step explanation:
All you need to do is figure out the missing angles. We know that the three angles in a triangle add up to 180 degrees.
For angle B in ABC, 180-52-39= 89. So angle B = 89 degrees.
For angle D in DEF, 180-39-89= 52. So angle D = 52 degrees.
Then see if the order of the angles match up.
DEF = 52 degrees, 89 degrees, 39 degrees
ABC = 52 degrees, 89 degrees, 39 degrees
The order of the same angles match, so triangle DEF and triangle ABC are equal.
Answer:
Yes, triangle DEF is similar to triangle ABC because their corresponding angles are the same size.
Step-by-step explanation:
Interior angles of a triangle sum to 180°.
⇒ ∠A + ∠B + ∠C = 180°
⇒ 52° + ∠B + 39° = 180°
⇒ ∠B = 89°
⇒ ∠D + ∠E + ∠F = 180°
⇒ ∠D + 89° + 39° = 180°
⇒ ∠D = 52°
Two triangles are similar if their corresponding angles are the same size.
If ΔDEF ~ ΔABC then:
∠D = ∠A∠E = ∠B∠F = ∠CFrom inspection of the given diagram:
∠D = 52° and ∠A = 52° so ∠D = ∠A∠E = 89° and ∠B = 89° so ∠E = ∠B∠F = 39° and ∠C = 39° so ∠F = ∠CTherefore, the triangles are similar because their corresponding angles are the same size.
Emily loves to go the spa she and her friends go twice a month each visit she gets a 90 minute massage for $125 and a deluxe manicure and pedicure for $65. How much does she spent at the spa each month?
Answer: $380
Step-by-step explanation:
First, we will find the price per visit using addition.
$125 + $65 = $190
Next, we notice it says "twice a month" in the question. We will multiply the value above by two to find the price per month.
$190 * 2 = $380
Answer:
twice a month of 125 + 65
2($125 + $65)
= 2($190)

To determine the longest wavelength photon which can remove an electron from mercury metal, we need to use the equation:
wavelength = hc/work function
What are photons?Photons are just light particles. Photons are basic subatomic particles that convey the electromagnetic force (and so much more). The photon is the basic unit of electromagnetic radiation, or the "quantum."
What is wavelength?A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places (adjacent crests) in the consecutive cycles. This length is often defined in wireless systems in meters (m), centimeters (cm), or millimeters (mm) (mm).
To determine the longest wavelength photon which can remove an electron from mercury metal, you need to use the equation:
wavelength = hc/work function
where h is the Planck constant (6.626 x 10^-34 Js), c is the speed of light (2.998 x 10^8 m/s), and work function is the minimum energy needed to remove an electron from the metal, in this case 4.475 eV.
Plugging these values into the equation gives:
wavelength = (6.626 x 10^-34 Js)(2.998 x 10^8 m/s)/(4.475 x 1.602 x 10^-19 J/eV)
This simplifies to:
wavelength = 404.4 nm
So, the longest wavelength photon which can remove an electron from mercury metal is 404.4 nm.

Find (f - g)(x), if f(x) = 2x2 + 2 and g(x) = 6x2 + 6.
To find (f - g)(x), you can subtract g(x) from f(x):
(f - g)(x) = f(x) - g(x)
= (2x2 + 2) - (6x2 + 6)
= -4x2 + (-4)
= -4(x2 - 1)

The measure of an angle X is 11° and 3X+2°=35° , 4X-9° =35° .
What is meant by an angle?In Euclidean geometry, an angle is a figure made up of two rays that have a shared vertex, also known as a common terminus, and are referred to as the angle's sides. The angles of two rays are situated in the plane containing the rays. An angle is also created when two planes intersect at an angle. These are referred to as dihedral angles. Another technique to define two curves is to specify the angle generated by rays that are tangent to the intersection of two curves. Angle is another word for how long a rotation or angle is.
∠QPA = ∠UPA

A company has found that the demand for its product varies inversely as the price of the product. When the price x is 4.75 dollars, the
demand y is 500 units.
Find a mathematical model that gives the demand y in terms of the price x in dollars.
With the help of algebra mathematical model equation for demand of company's product is given by the equation d = 1800 / p.
What is algebra?
The area of mathematics known as algebra deals with the representation of problems as mathematical expressions. For a mathematical expression to have meaning, it needs to include variables like x, y, and z as well as mathematical operations like addition, subtraction, multiplication, and division.
Let demand for company's product d vary inversely with its price p, which means
d ∝ ( 1/p ) or d = k * ( 1/ p) = k / p ----- 1
As when p = 4.5, d = 400
Putting these in (1), we get 400 = k/ 4.5
Hence #k=400 x 4.5=1800 and our model equation is
d = 1800/p
Hence mathematical model equation for demand of company's product is given by the equation d = 1800 / p.

Answer:
100.72 meters
Step-by-step explanation:
To find the total length of the race, we need to sum:
The distance from the starting line to the first hurdle.The distances between the hurdles.The distance from the last hurdle to the finish line.The distance from the starting line to the first hurdle is 13.72 meters.
The distance between each of the 10 hurdles is 8.5 meters.
There are 9 spaces between hurdles 1 and 10, so the distance between the hurdles is 9 × 8.5 = 76.5 meters.
The distance from the last hurdle to the finish line is 10.5 meters.
To find the total length of the race, add these distances together:
[tex]\begin{aligned}\textsf{Total length of the race} &=\sf 13.72\; meters + 76.5\; meters + 10.5 \;meters\\\\&=\sf 100.72\; meters\end{aligned}[/tex]

where Ï is non real cube root of unity choose the correct answer. abc+bcd+acd+abd is equal to
First, we can rewrite the given equation as:
1/a+Ï + 1/b+Ï + 1/c+Ï = (1/Ï)(1/a + 1/b + 1/c)where Ï is the non real cube root of unity.
We can then multiply both sides of the equation by Ï to get:
1/a + 1/b + 1/c = 2(1/a + 1/b + 1/c)This simplifies to:
1/a + 1/b + 1/c = 0Since a, b, and c are all real numbers, we know that 1/a, 1/b, and 1/c are also real numbers. Therefore, the sum of these three real numbers must also be a real number. The only way that 1/a + 1/b + 1/c can equal 0 is if all three of these terms are equal to 0.
Thus, we can conclude that a = b = c = 0.
Since a, b, and c are all equal to 0, we know that abc + bcd + acd + abd must also equal 0. Therefore, the answer is 0.
