If A={s, t, a, r} and B={m, a, t, h}, find A ∩ B.
A ∩ B = { t,a }
This is because it is asked to find the common elements present in both sets.
We need to write only the same elements present in both sets.
Therefore, A ∩ B = { t,a } is the answer.

Use the quadratic function to predict y if x equals 6.
y = 2x^2 − 2x − 2
A. y = −58
B. y = −60
C. y = 60
D. y = 58
Answer:
D. y = 58
Step-by-step explanation:
Answer:
The value of the polynomial is 58 for x = 6.
Step-by-step explanation:
Here, the given quadratic function polynomial is given as:
or,
Now, to find the value of y, when x = 6
⇒
= 2(36 - 6 -1) = 2(29)
= 58
⇒y(6) = 58
Hence, the value of the given polynomial is 58 for x = 6.
Find the value of x.

Given triangle MTW is congruent to triangle BGK,find y.
Answer:
y = 8
Step-by-step explanation:
As MTW and BGK are congruent
angle T = angle G
4x - 3 = 45
in triangle MTW
angle M = 180 - (T + W)
= 180 - (45 + 41)
= 180 - 86
= 94
and angle M = B
11y + 6 = 94
11y = 94 - 6
11y = 88
y = 8

The area of rectangle ABCD is 28 cm^2
a) What is the length of side AB in terms of x?
b) If the area of rectangle ABCD is 28cm^2
we can show that x2 + ax=b
a and b are integer values.
Work out the values of a and b.
The length of AB is (x + 4) cm and the values of a and be are a = 10, b = 4
A rectangle is a quadrilateral in which opposite sides are equal and parallel to each other. The area of a rectangle is:
Area = length * width
From the image:
Length of AB = x + 4
Length of BC = x + 6
The area of rectangle ABCD = Length of AB * Length of BC
28 = (x + 4)(x + 6)
x² + 10x + 24 = 28
x² + 10x = 4
Comparing with x² + ax = b gives:
a = 10, b = 4
Therefore the length of AB is (x + 4) cm and the values of a and be are a = 10, b = 4

Answer:
Step-by-step explanation:
2x + y = 6
y = -2x + 6
Comparing this with y = 1/2x - 7
Multiplying the 2 slopes:
-2 * 1/2
= -2/2
= -1
- this means that the 2 lines are perpendicular.

Answer:
$22100
Step-by-step explanation:
9/10 = 0.9
5/8 = 0.625
0.9 + 0.625 = 1.525
3 + 1 = 4
4 + 1.525 = 5.525
5.5 = $22000
0.025 = $100

Feliciano is using a pretest/posttest design to conduct an experiment on improving children’s handwriting, employing two different techniques of improving handwriting and a control condition. In the results, the two groups who receive the treatment don’t show any difference from each other. Feliciano believes that there is a difference but that his 3-point assessment scale of handwriting cannot detect it. Identify the true and false statements about Feliciano’s study. True Statement(s) Drag appropriate answer(s) here Feliciano is most concerned about using an insensitive measure. Press Space to open To address his concern, Feliciano should use a scale with more levels for his dependent variable. Press Space to open To address his concern, Feliciano should use a manipulation check for his independent variable. Press Space to open To address his concern, Feliciano should increase his sample size. Press Space to open Feliciano is most concerned about measurement error.
The test result can be made more responsive by adjusting the parameters
of the test.
Feliciano should use a scale with more levels for his dependent variableFeliciano should use a manipulation check for his independent variable Feliciano should increase the sample size.Reasons:
The type of experiment being performed by Feliciano is children
handwriting improvement based on two techniques and a control condition.
The number of groups that receive the treatment = Two
The assessment method used = 3-point assessment scale
The true statements are;
Feliciano should use a scale with more levels for his dependent variableIncreasing the number of levels on the scale, increases the variability of the response such that more responses can be obtained from the participants than when using a 3-point scale, based on the closeness between the the variables being assed.
Feliciano should use a manipulation check for his independent variableA manipulation check can be used to determine the effectiveness of the treatment applied , such as the inclusion of question that finds out about the participants association to the treatment.
Feliciano should increase the sample sizeIncreasing the sample size increases the z-value, and makes it more likely to reject the null hypothesis, that there is no difference between the two groups.

Which expressions simplify to 0? Check all that apply.
8g – 8g
(–2g) – 2g
5g + (–5g)
One-half g + one-half g
Negative two-thirds g + two-thirds g
The expressions that simplify to zero are:
8g – 8g
5g + (–5g)
Negative two-thirds g + two-thirds g
Let us consider each of the expressions to determine the ones that simplify to zero (0)
For 8g - 8g
This is a direct subtraction of terms of the same value. Therefore, 8g - 8g = 0
For (–2g) – 2g
This can be further simplified as -2g - 2g = -4g
Therefore, (–2g) – 2g does not simplify to zero
For One-half g + one-half g
This can be written mathematically as:
[tex]\frac{1}{2}g + \frac{1}{2}g = g[/tex]
Therefore, One-half g + one-half g does not simplify to zero
Negative two-thirds g + two-thirds g
[tex]-\frac{2}{3}g+ \frac{2}{3}g = 0[/tex]
Therefore, Negative two-thirds g + two-thirds g simplifies to zero
