Answer:
The equation is;
T = 87.4 ± 1.5
Maximum value of T = 88.9 °F
Minimum value of T = 85.9 °F
Step-by-step explanation:
We are given the stated temperature as 87.4 °F
Now, we are told that this stated temperature differs from the actual temperature by no more than 1.5 degrees Fahrenheit.
Thus, if the actual temperature is T, it means that T should either be 1.5 more than 87.4 or 1.5 less than 87.4.
Thus the equation is;
87.4 ± 1.5 = T
So maximum value of T = 87.4 + 1.5 = 88.9 °F
While minimum value of T = 87.4 - 1.5 = 85.9 °F
If ∠ABD and ∠CBD are a linear pair, m∠ABD = (3x+31)°, m∠CBD = (2x-6)°, then find m∠ABD. *
Answer:
∠ ABD = 124°
Step-by-step explanation:
A linear pair of angles sum to 180°, thus
∠ ABD + ∠ CBD = 180 , substitute values
3x + 31 + 2x - 6 = 180, that is
5x + 25 = 180 ( subtract 25 from both sides )
5x = 155 ( divide both sides by 5 )
x = 31
Thus
∠ ABD = 3x + 31 = 3(31) + 31 = 93 + 31 = 124°

The domain refers to values on the X-axis, and as you can see there are arrows on the orange line, meaning it goes on "forever". This is all real numbers.
The y-axis (range) has the line go through at -2. The line is pointing up, which means all the numbers are greater than -2, or could be equal to -2.

Answer:
36
Step-by-step explanation:
First of all, the area of a circle is always pi(r)^2, which we can then substitute values. We will get pi(10)^2, and once we simplify that, we get 100pi as the area. Since we know that the area of the shaded sector is 10 pi, we can divide 10pi by 100pi to get 1/10. 1/10 is the area of the shaded sector compared to the area of the whole circle. Multiply 1/10 by the angle measure of a circle, which is 360, to get 36 degrees.

Step-by-step explanation:
Domain is set of input values and range is set output values.
For the function f(x) = 2x² - 8 and domain set of {-2, 3, 5}
Range is:
f(-2) = 2(-2)² - 8 = 0f(3) = 2*3² - 8 = 10f(5) = 2*5² - 8 = 42Range: {0, 10, 42}

When Emmett began his science experiment, he has 20 millimeters of an unknown solution. During the experiment, the change in the volume of the solution was -9 milliliters. What was his final volume of the solution.
To solve the problem, dakota added 20+( -9 ) and came up with an answer of -11 milliliters. Is Dakota correct? Why or why not ?
A : yes, dakota is correct
B: No. The answer should have been 11 milliliters, not -11 milliliters, because the volume should not be negative
C: No. Dakota should have subtracted 20 - (-9) because the volume decreased
Answer:
no the answer should be 11

Write an equation in slope-intercept form of the line that is a segment bisector of both AB and CD. Ay 4 B(6,3) A(-4,1) -4 -2 2. 4 6 X D(5, -1) -2 4 C1-1,-5) -6
Answer:
y = -5x + 7
Step-by-step explanation:
Given that the location of the points are:
A(-4, 1), B(6, 3), C(-1, -5) and D(5, -1)
The location of the bisector of a line is given as:
[tex]x=\frac{x_1+x_2}{2} \\\\y=\frac{y_1+y_2}{2}[/tex]
If E(x1, y1) is the bisector of segment AB then the location of E is at:
[tex]x_1 =\frac{-4+6}{2}=1 \\\\y_1=\frac{1+3}{2}=2[/tex]
Hence E is at (1, 2)
If F(x2, y2) is the bisector of segment CD then the location of F is at:
[tex]x_2 =\frac{-1+5}{2}=2 \\\\y_2=\frac{-5-1}{2}=-3[/tex]
Hence F is at (2, -3)
Hence the line that is a segment bisector of both AB and CD pass through the point (1, 2) and (2, -3).
The equation of the line is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-2=\frac{-3-2}{2-1}(x-1)\\ \\y-2=-5(x-1)\\\\y-2=-5x+5\\\\y=-5x+7[/tex]
Answer: The equation is: y = -5x + 7.
Step-by-step explanation:
Given that the location of the points are:
A(-4, 1), B(6, 3), C(-1, -5) and D(5, -1).
Midpoint of A(-4, 1), B(6, 3) is = [tex]\left(\frac{\left(-4+6\right)}{2},\frac{\left(1+3\right)}{2}\right)=(1,2)[/tex].
Midpoint of C(-1, -5) and D(5, -1) is [tex]\left(\frac{\left(-1+5\right)}{2},\frac{\left(-5-1\right)}{2}\right)=(2,-3)[/tex].
Using point slope formula:
[tex]\frac{y-2}{x-1}=\frac{-3-2}{2-1}\\\frac{y-2}{x-1}=-5\\y-2=-5x+5\\y=-5x+7[/tex]

Janelle is using a piece of cardstock to create an open box with no top. The cardstock is 8 inches by 11 inches. She cuts a square with length out of each corner and folds up the sides to create the box. Find the volume of the box, , in standard form.
Answer: 4x^3-38x^2+88x
Step-by-step explanation:
The volume of the box in standard form is 4x³ - 38x² + 88x
Since Janelle cuts a square of side length x out of each corner of the cardstock, we have a length x + x = 2x cut out of each dimension of the cardstock.
Since the dimensions of the cardstock are 8 inches by 11 inches, cutting out a length of 2x inches from each dimension to produce the length, L and width, w of the open box, we have the length of the open box, L = 8 -2x and the width of the open box, W = 11 - 2x.
Since the height of the open box is the length x of the square cut out of each corner, and the open box is a rectangular box,
So, the volume of the box is
V = LWx
Substituting the values of the variables into the equation, we have
V = LWx
V = (8 - 2x)(11 - 2x)x
Expanding the brackets, we have
V = (88 - 16x - 22x + 4x²)x
V = (88 - 38x + 4x²)x
V = 88x - 38x² + 4x³
Re-arranging, we have
V = 4x³ - 38x² + 88x
So, the volume of the box in standard form is 4x³ - 38x² + 88x

Answer:
Step-by-step explanation:
It's given in this question,
Length of side AB = length of side CD = 5 units
Length of side BC = length of side AD = 2 units
If the given quadrilateral is translated lengths of all the image sides will not be equal because translation of a figure is a rigid transformation.

Answer:
-2
Step-by-step explanation:
You need to add a positive number and a negative number.
This is how you add a positive number and a negative number.
First, get rid of the signs and make them both positive.
Now you have 5 and 3.
Do a subtraction the way you first learned subtraction in elementary school, which is the larger number minus the smaller number.
5 - 3 = 2
The answer is either 2 or -2.
To finish the original addition, look at the two original numbers. 5 is greater than 3. 5, the greater value, is on a negative number, so the answer is negative.
3 + (-5) = -2

What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that y = 2x and 3x – 3y = 2, therefore, if we substitute the value of y from y=2x into the second equation 3x-3y=2, then,
3x – 3y = 2
3x – 3(2x) = 2
3x – 6x = 2
–3x = 2
x = 2/–3
Hence, the value of x in the two of the given equations is 2/–3.
