Evaluate the following expression using the values given: Find 2r2 + 3s3 − r2 + 4t2 − r2 if r = −2, s = −3, and t = 5.
Answer:
The evaluated answer to this equation is 19.
Step-by-step explanation:
2r² + 3s³ - r² + 4t² - r²
In the problem, we are given values for the variables in the equation.
r = -2
s = -3
t = 5
Let's plug these numbers into the equation.
2(-2)² + 3(-3)³ - (-2)² + 4(5)² - (-2)²
First, simplify the exponents.
2(4) + 3(-27) - (4) + 4(25) - (4)
Next, multiply the numbers starting from left to right.
8 + (-81) - 4 + 100 - 4
Add 8 and -81 together.
-73 - 4 + 100 - 4
Subtract 4 from -73.
-77 + 100 - 4
Add -77 to 100.
23 - 4
Subtract 4 from 23.
19
So, your final simplified answer to this equation is 19.

Which of the following r-values represents the strongest correlation?
Answer:
A. -0.91
Step-by-step explanation:
Correlation coefficient is represented by values from -1 to 1. The closer the value is to -1 or 1, the stronger the correlation coefficient, which indicates that the data points being plotted on a scatter plot are clustered more closely along the best line of fit.
Correlation could be positive or negative.
If negative, it means, as one variable increases, the other variable decreases also. But, if positive, it means as one variable increases, the other variable increases also, or as one variable decreases, the other decreases also. Both change in the same direction.
A correlation coefficient that has a value closer to -1 shows a strong negative correlation. Meaning, the data points are clustered closely along the line slope on the scatter plot.
Therefore, r-value that is the strongest among the given options in the question is -0.91.
The answer is A. -0.91.

Choice A: -36 + (-8)
Step-by-step explanation:
We want to find the equivalent expression to -36 - 8
The correct option is Choice A.
Choice A is -36 + (-8)
The reason is that the product of the signs + and - is -, i.e.
+ * - = -
Hence, + (-8) is the same thing as -8 and Choice A becomes -36 - 8
Can someone help me solve this?
What is side b? Thank you
Answer:
The answer is
b = 39.32 feetStep-by-step explanation:
To find side b we use cosine
cos ∅ = adjacent / hypotenuse
From the question
side c is the hypotenuse
side c = 48 feet
side b is the adjacent
∅ = 35°
We have
cos 35 = b/c
cos 35 = b / 48
b = 48 cos 35
b = 39.319
b = 39.32 feet to 2 decimal places
Hope this helps you
Answer:
b ≈ 39.32 ft
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos35° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{b}{c}[/tex] = [tex]\frac{b}{48}[/tex] ( multiply both sides by 48 )
48 × cos35° = b, thus
b ≈ 39.32 ft ( to 2 dec. places )
Carlos' hourly wage increased by 30% this year. If his previous salary was $20 an hour, what is his new hourly wage?

$26.
Step-by-step explanation:
His original salary was $20. It increased by 20%. In other words, the total salary he earns is now:
[tex]20+20(.3)=20(1.3)=26[/tex]
His new salary is $26.
Note: For the second step, I used the distributive property.
[tex]20(1)+20(.3)=20(1+.3)=20(1.3)[/tex]
Write the slope-intercept form of the equation of the line that has the same y-intercept as the black line shown and passes through the point (4, 4) on the blue line. Explain how you determined your answer.
Answer:
y = 0.5x + 2
Step-by-step explanation:
the y-intercept is 2, as shown in the graph
the slope is 0.5. this is because while the x-value goes up by 2, the y-value goes up by one (from 0, 2 to 2, 3).
using the slope formula of rise / run, you get 1/2, which is equal to 0.5
When using a debit card: Question options: A:There are always fees. b:Identification is always required. c:You still need to record transactions in your checkbook. d:You are not personally liable for more than $50 if it is stolen.
Answer:
D.
Step-by-step explanation:
Since this isn't a credit card, there are no interests or fees on a debit card, so A is incorrect. B is also incorrect. You only need identification when you are withdrawing or depositing at a bank, but purchases made in stores or online do not need your identification. You also don't need to record transactions in your checkbook (but it is recommend to keep track of purchases). Modern day technology already records transaction history and all you need to do is access it online.
D is correct because if someone steals your PIN for your debit card, they could go to stores and use that money. You can dispute charges and report to the bank if that happens.

Answer:
Monique made an error when writing the factored expression.
Step-by-step explanation:
The factorisation of the expression 4x+16xy is 4x(1+4y).
The given expression is 4x+16xy.
What is factorisation?In mathematics, factorization or factoring consists of writing a number or another mathematical object as a product of several factors, usually smaller or simpler objects of the same kind.
Now, 4x=2×2×x and 16xy=2×2×2×2×x×y
so, the GCF of terms 4x.

If Z1 = 12 + 6݅ and Z2 = a + bi (where a, b ∈ R) are two complex number, we can say that the product Z1Z2is imaginary A) If and only if ܽ = ܾ = 0 B) If b = 2a C) If a = −2b D) for each value of a and b
Answer:
A) if and only if a = 0
Step-by-step explanation:
Since Z1 = 12 + 6݅ and Z2 = a + bi , then the product, Z1Z2 = (12 + 6)(a + bi)
Z1Z2 = (12 + 6)(a + bi)
Expanding the brackets, we have
Z1Z2 = 12a + 12bi + 6a + 6bi
Collecting like terms, we have
Z1Z2 = 12a + 6a + 12bi +6bi
Z1Z2 = 12a + 6a + (12b +6b)i
Simplifying, we have
Z1Z2 = 18a + 18bi
For Z1Z2 to be imaginary, then the real part must be zero.
That is 18a = 0 ⇒ a = 0
So, Z1Z2 is imaginary if and only if a = 0
Which function has a minimum and is transformed to the right and down from the parent function, f(x) = x2? g(x) = –9(x + 1)2 – 7 g(x) = 4(x – 3)2 + 1 g(x) = –3(x – 4)2 – 6 g(x) = 8(x – 3)2 – 5
Answer:
[tex]g(x) = 8\cdot (x-3)^{2}-5[/tex]
Step-by-step explanation:
Given that parent function represents a parabola, the standard form with a vertex at (h,k) is now described:
[tex]y-k = C\cdot (x-h)^{2}[/tex]
[tex]y = C \cdot (x-h)^{2} + k[/tex]
Where:
[tex]x[/tex], [tex]y[/tex] - Independent and dependent variables, dimensionless.
[tex]h[/tex], [tex]k[/tex] - Horizontal and vertical component of the vertex, dimensionless.
[tex]C[/tex] - Vertex factor, dimensionless. (If C > 0, then vertex is an absolute minimum, but if C < 0, there is an absolute maximum).
After reading the statement of the problem, the following conclusion are found:
1) New function must have an absolute minimum: [tex]C > 0[/tex]
2) Transformation to the right: [tex]h > 0[/tex].
3) Transformation downwards: [tex]k < 0[/tex]
Hence, the right choice must be [tex]g(x) = 8\cdot (x-3)^{2}-5[/tex].

NEED ANSWER ASAP What is the location of point G, which partitions the directed line segment from F to D into an 8:5 ratio?
Answer:
(A) 1
Step-by-step explanation:
We know that the formula is x = (m/m+n) (x2-x1) + x1.
But the trick to the question which is why everyone is getting it wrong is because it asks for F to D not D to F.
The reason everyone else was getting 4 was because they were using this.
They solved the equation x = (8/8+5) (9-[-4]) -4 where it was D to F. This equation does turn out to be 4 but it is incorrect.
However, the correct equation (because it is supposed to be F to D) is
x = (8/8+5) (-4 -9) +9 which is in fact equal to 1.

Subtract 37 from each side
38-37 = z
1 =z
Answer:
y = 7
z = 1
Step-by-step explanation:
The triangles are congruent, the length of the sides are equal.
y + 34 = 41
y = 41 - 34
y = 7
z + 37 = 38
z = 38 - 37
