Answer:
[tex]d = \sqrt{109}[/tex]
Step-by-step explanation:
Use the distance formula.
[tex]\text{The distance between two points } (x_1, y_1) \text{ and } (x_2, y_2) \text{ is given by the formula:}\\d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Your points are (-4, 11) and (6, 8).
[tex]d = \sqrt{(-4 - 6)^2 + (11 - 8)^2}\\\\d = \sqrt{(-10)^2 + (3)^2}\\\\d = \sqrt{100 + 9}\\\\d = \sqrt{109}[/tex]

the table shows the cost of the daycare for Lucy's dog this week her dog went 3 full days of day care and 2 half days of day care write an expression for the total cost of this week day care then evaluate the expression
An expression for the total cost of the daycare for Lucy's dog this week is T = 3F + 2H and the total cost is equal to $114.
How to write an expression for the total cost?In this exercise, you're required to write an expression for the total cost of the daycare for Lucy's dog this week. Thus, we would assign a variable to the cost for full-day and half-day day care as follows:
Let the cost for full-day be F.Let the cost for half-day be H.Let total cost be T.Thus, the total cost of the daycare is given by:
T = 3F + 2H
Evaluating the expression, we have:
T = 3(28) + 2(15)
T = 84 + 30
T = $114.

Answer:

Step-by-step explanation:
Translations
For [tex]a > 0[/tex]
[tex]f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}[/tex]
[tex]y=a\:f(x) \implies f(x) \: \textsf{stretched parallel to the y-axis (vertically) by a factor of}\:a[/tex]
Parent function
[tex]y=x^2[/tex]
Translated 7 units to the right
Subtract 7 from the x-value:

Vertically stretched by a factor of 3
Multiply the whole function by 3:
[tex]3f(x) \implies y=3(x-7)^2[/tex]
Streched 7 units right means change in x

Decide whether quadrilateral ABCD with vertices 4(3,1), B(-1,-1) C(1,3), and D(5,5) is a rectangle, rhombus,
square, or parallelogram.
Answer: rectangle
Step-by-step explanation:
From the options, it is implied that it is a parallelogram.
From inspection, we can tell that not all the sides are congruent, so it is not a rhombus or a square.
To determine if it is a rectangle, we can use the slope formula to see if there is a pair of perpendicular sides (if this is the case, then this will be a parallelogram with a right angle, making it a rectangle)
[tex]m_{\overline{AB}}=\frac{1-0}{-4-(-3)}=-1\\m_{\overline{BC}}=\frac{4-1}{-1-(-4)}=1\\\therefore \overline{AB} \perp \overline{BC} \text{ because} \left(m_\overline{AB} \right) \left(m_{\overline{BC} \right)=1[/tex]
So, the most specific classification is a rectangle.

Solve |5x + 30| = 10x Identify the solution and an extraneous solution
Answer:
B
Step-by-step explanation:
the absolute value function always gives a positive result
However, the value inside can be positive or negative, that is
5x + 30 = 10x or - (5x + 30) = 10x
solving both
5x + 30 = 10x (subtract 5x from both sides )
30 = 5x ( divide both sides by 5 )
6 = x
or
- (5x + 30) = 10x
- 5x - 30 = 10x ( add 5x to both sides )
- 30 = 15x ( divide both sides by 15 )
- 2 = x
As a check
substitute these values into the equation and if both sides are equal then it is a solution.
x = 6
left side = | 5(6) + 30 | = | 30 + 30 | = | 60| = 60
right side = 10(6) = 60
Then x = 6 is a solution
x = - 2
left side = | 5(- 2) + 30 | = | - 10 + 30 | = | 20 | = 20
right side = 10(- 2) = - 20 ≠ 20
Thus x = - 2 is an extraneous solution
440 meters is 14
of the way around the race track. How far is it around the whole race track?
Answer:
440x4=2200
Step-by-step explanation:
I'm guessing you meant 1/4, which is also known as 0.25, and if you know that 440 meters is equal to 1/4th of the whole race track you just have to multiply 440 by 4.
find the volume of the pyramid. round to the nearest hundredth
Answer:
A. 17.35 mm³
Step-by-step explanation:
Volume of a Pyramid
[tex]V = \frac{1}{3}Bh[/tex]
V ... volume
B ... area of base
h ... height
The base of this pyramid is a square. Area of a square is side times side.
[tex]B = 3.5 \times 3.5[/tex]
Let's substitute in the formula.
[tex]V = \frac{1}{3}Bh\\\\V = \frac{1}{3}(3.5\times 3.5)(4.25)\\\\V = \frac{1}{3}(12.25)(4.25)\\\\V \approx 17.35417 \text{ mm}^3[/tex]
Now let's round to the nearest hundredth.
V = 17.35 mm³
This is a dot plot of the number of text messages sent in a day by a sample of students at a local high school. The sample consisted of 30 students and was selected as representative of the population.
a. What do the six values of 0 on the dot plot represent?
b. Since the sample is representative of the population, describe what you think the dot plot of the entire population will look like.
The six values of 0 shown on the dot plot represent that 6 students out of the 30 sampled did not send any text messages daily.
With the sample being representative of the population, a dot plot for the entire population would have the same proportions as the sample but with a larger number of students.
What does the dot plot show?The number of dots above a number indicates the number of students who send that number of text messages daily.
As there are 6 dots over 0, it means that 6 students do not send any text messages daily.
Seeing as the sample is representative of the entire population, a dot plot for the whole school would have a larger number of dots over each number but the proportions would be the same as the sample.
For instance, the proportion of total students who don't send any messages per day is:
= 6 / 30
= 20%

A. Inductive
B. Deductive
C. Neither
