Answer:
Expressions A, E, and F
Step-by-step explanation:
In general, when negative integers are multiplied; if the negative integers are even, then the product would be positive. But if the negative integers are odd, then the product would be negative.
Thus,
A. (−5)(−0.4)(1.8) = (2.0)(1.8)
= 3.6
B. (-45)(-19)(-112) = (855)(-112)
= -95760
C. −1(5+17) = -1(22)
= -22
D. (−5)(−0.4)(1.8)(−3.25) = (2.0)(-5.85)
= -11.7
E. (-49)(-34)(-12)(-12) = (1666)(144)
= 239904
F. −1(3.5−7) = -1(-3.5)
= 3.5
Thus expressions A, E and F have positive products.

The area of a square is represented by the expression 16x4y8. Which expression could represent the length of one side of the square?
Answer:
4 sq 8
Step-by-step explanation:
The expression that could represent the length of one side of the square is; [tex]4x^2y^4[/tex].
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbol it can also be used to indicate the logical syntax's order of operations and other features.
Given that;
The area of the square A = [tex]16x^4y^8[/tex]
Consider that a is the side length of the square
The area of the square is given by;
[tex]\Rightarrow A=(\text{side length})^2[/tex]
So, we can write the expression as;
[tex]\Rightarrow a^2=16x^4y^8\\\\\Rightarrow a=4x^2y^4[/tex]
Hence, the length of each side is 4x^2y^4

What is the equation of the graphed line written in
standard form?
Ox-4y = 4
Ox+4y = 4
(4,0)
Oy-x-1
Oy-1
45
o,-1)
Answer:
the third option is the answer, y= 1/4x-1
Step-by-step explanation:
graph line in standard form:
[tex]y = mx + c[/tex]
where m = slope and c = y-intercept
1) find the slope
slope formula:
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
use the two coordinates given in the graph
i/ (0,-1)
x1 = 0
y1 = -1
ii/ (4,0)
x2 = 4
y2 = 0
substitute the values into the formula
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
[tex] \frac{0 - ( - 1)}{4 - 0} [/tex]
[tex] \frac{1}{4} [/tex]
thus, m = 1/4
2) find the y-intercept
* y-intercept is the value of y that cuts through the y-axis
based on the graph, the y-intercept is -1
thus, c = -1
3) substitute the value of m and c into the standard form formula
[tex]y = mx + c[/tex]
[tex]y = \frac{1}{4} x - 1[/tex]

In the diagram mz3= x+ 30 and mz4 =2x-80. What is the measure of angle 3?
Given:
Consider the below figure attached with this question.
[tex]m\angle 3=(x+30)^\circ[/tex] and [tex]m\angle 4=(2x-80)^\circ[/tex].
To find:
The measure of angle 3.
Solution:
From the below figure it is clear that, angle 3 and angle 4 are vertically opposite angles.
We know that, vertically opposite angles are always equal. So,
[tex]m\angle 3=m\angle 4[/tex]
[tex](x+30)^\circ=(2x-80)^\circ[/tex]
[tex]x+30=2x-80[/tex]
[tex]x-2x=-30-80[/tex]
[tex]-x=-110[/tex]
[tex]x=110[/tex]
Now,
[tex]m\angle 3=(110+30)^\circ[/tex]
[tex]m\angle 3=140^\circ[/tex]
Therefore, the measure of angle 3 is 140 degrees.

Jasmine has taken an online boating course safety course and now completing her end-of-course exam . As she answers each question , the progress bar at the bottom of the screen shows what portion of the test she has finished. She has just completed Question 16 and the progress bar shows she is 20% complete. How many total questions are on the test ?
Answer:
80
Step-by-step explanation:
20 percent is 16 questions
then 100/20=5
5 times 16 is 80
the depth of water at the end of a boat dock can be modeled by a senusoidal function Y=Asin [B(r+C) ]+D where y represents the depth in feet of the water, hours after midnight on a certain day, the depth is 10 feet at low tide at 6 am and 18 feet at high tide at noon find the amplitude and midline for the general sine function that can be used to model the water's depth.
Answer:
A=4 ft
Midline: y=14
Step-by-step explanation:
When talking about sinusoidal waves, we know the amplitude will be the distance between the midline and the highest or lowest point of the graph. This can be found by first, finding the distance between the lowest point and the highest point:
d= 18ft - 10ft = 8ft
and divide this distance into 2:
[tex]A=\frac{8}{2}[/tex]
A= 4 ft
in order to find the midline, we need to figure the midpoint between the highest and lowest value. We can do so by using the following formula:
[tex]Midpoint=\frac{high+low}{2}[/tex]
so:
[tex]Midpoint=\frac{18+10}{2}[/tex]
Midpoint = 14
so the midline is located at the line:
y=14
The ratio of the measures of the sides of a triangles is 9:7:3. If the perimeter of the triangle is 266 inches, find the value of x
Answer: Depends on which side x is...
Step-by-step explanation:
This is my strategy for finding the values using ratios
Add the ratio together: 9 + 7 + 3 = 19
Divide the perimeter by the sum of the ratio: 266/19 = 14
Now we know what a unit of one is on the ratio: 14
Multiply this unit by the ratio amount
Side with ratio 9: 9 × 14 = 126 inches
Side with ratio 7: 7 × 14 = 98 inches
Side with ratio 3: 3 × 14 = 42 inches

Answer:
1 = Given
2 = Given
3 = Substitution Property
4 = Distributive Property
5 = Given
6 = Substitution Property
7 = Simplify
8 = Subtraction Property
9 = Addition Property
By substituting given c and d values inn the given equation and simplifying we get a=b. Hence, proved.
Given that, 2c =d-2b, c = a-b and d= a + b.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
To prove: d=a+b
Proof:
1. 2c =d-2b (Given)
2. c=a-b (Given)
3. 2(a-b)=d-2b (Substitute c=a-b)
4. 2a-2b=d-2b
5. d=a+b (Given)
6. 2a-2b=a+b-2b (Substitute d=a+b)
7. 2a-2b=a-b
8. a-2b=-b (Transpose a to LHS and simplify)
9. a=b (Transpose a to RHS and simplify)
By substituting given c and d values inn the given equation and simplifying we get a=b. Hence, proved.
