What is the distance in units between (15,-17) and (-20,-5)
Answer:
41.34
Step-by-step explanation:
We can use the Pythagorean theorem to solve for the distance. First we will create an imaginary triangle with the leg lengths being the x distance and y distance between the 2 points and the hypotenuse being the distance between the 2 points.
x distance =
[tex]15 - (-20) = 35[/tex]
y distance =
[tex] |-17-5| = | - 22| = 22[/tex]
We can now use the Pythagorean theorem (a²+b²=c²) with our imaginary triangle
xdistance²+ydistance²=distance²
35²+22²=distance²
1709=distance²
[tex] \sqrt{1709} = distance[/tex]
In decimal form the distance would be around 41.34.
That is the answer

Triangle DEF, with vertices D(9,-8), E(8,-3), and F(2,-5), is drawn inside a rectangle,
as shown below.
What is the area, in square units, of triangle DEF?
[
Answer: A=?
units²
The area of the triangle DEF is 2 square units
How to determine the area?The given parameters are:
D(9,-8), E(8,-3), and F(2,-5),
The area of the triangle is calculated using:
Area = 0.5|x1 * (y2 -y3) + x2 * (y1 -y3) + x3 * (y2 -y1) |
This gives
Area = 0.5|9 * (-3 + 5) + 8 * (-8 + 5) + 2 * (-3 + 8) |
Evaluate
Area = 0.5|4|
Expand
Area = 2
Hence, the area of the triangle DEF is 2 square units

one point.
Determine the values of x, y, and z
Answer:
z=98 degrees
x=64 degrees
y=18 degrees
Step-by-step explanation:
y is congruent to 18 since theyre opposite of eachother, same with x and 64. find z by using the straight 180 line. (180=64+18+z, so z=98)
Find the value of x and y from the following figure.

garcia is modeling the equation 5x
The Chang family is on their way home from a cross-country road trip. During the trip, the function D(t)=3260−55t can be used to model their distance, in miles, from home after t hours of driving.
part A:Find D(12) and interpret the meaning in the context of the problem.
part B: If D(t)=2490, find the value of t and interpret its meaning in the context of the problem.
Considering the given function, we have that:
a) D(12) = 2600, which means that after 12 hours of driving, the family is 2600 miles from home.
b) D(t) = 2490 when t = 14, which means that the family is 2490 miles from home after 14 hours of driving.
What is the function in this problem?The distance that the family is from home, after t hours of driving, is given by:
D(t) = 3260 - 55t.
Then, after 12 hours, the distance is given by D(12), that is:
D(12) = 3260 - 55 x 12 = 2600.
D(12) = 2600, which means that after 12 hours of driving, the family is 2600 miles from home.
D(t)=2490, hence:
3260 - 55t = 2490
55t = 770
t = 770/55
t = 14
D(t) = 2490 when t = 14, which means that the family is 2490 miles from home after 14 hours of driving.

Determine if the following polygons are similar.
Problem 1
Triangle ABE is similar to triangle DCE. This is because we have two pairs of congruent corresponding angles.
angle AEB = angle DEC (vertical angles)angle ABE = angle DCE (alternate interior angles)Refer to the angle angle (AA) similarity theorem for more info.
-------------------
For the other pair of triangles, we don't have enough info to determine if they are similar or not. We have info about one pair of sides, and a pair of angles, but that's about it.
We need to know if JL is proportional to MO, and in the same ratio as KL & NO are, if we wanted to use the side angle side (SAS) similarity theorem.
-------------------
Summary:Triangle ABE is similar to triangle DCE by the AA (angle angle) similarity theoremWe don't have enough info to know if triangles JKL and MNO are similar or not.============================================================
Problem 2
Divide the corresponding sides
LN/PO = 30/15 = 2LN/OQ= 26/13 = 2ML/QP = 26/13 = 2We see the three ratios are equal to the same value (2) and that proves the triangles LNM and POQ are similar by the SSS (side side side) similarity theorem.
-------------------
Like before, we'll divide the corresponding sides
1st Rectangle: horizontal/vertical = 10/4 = 2.52ndRectangle: horizontal/vertical = 3/8 = 0.375We don't have a match. Let's try rotating the second rectangle so that the side '8' is horizontal, and the side '3' is vertical
1st Rectangle: horizontal/vertical = 10/4 = 2.52nd Rectangle: horizontal/vertical = 8/3 = 2.67 approximatelyWe don't have a match here either. There are other approaches we could take, but basically the two rectangles are not similar.

When given such a problem we have to methods to handle this:
substitution methodelimination method.On this problem, let's limit ourself to substitution method;
x + y = 27 ..................... eq.1
y = 2x ........................ eq.2
Eq.2 is already manipulated. Substitute it into eq.1
x + y = 27
=> x + 2x = 27
3x = 27
x = 9
Substitute x into eq.2
y = 2 (9)
= 18
In terms of x and y;
(x, y) => (9, 18)

three consecutive odd integers have a sum of 51. what is the smallest integer
Answer:
15
Step-by-step explanation:
Let 2n+1 be the first odd integer.
Therefore, the consecutive odd integers will be 2n+3 and 2n+5
If the sum of the consecutive odd integers is 51 then:
⇒ 2n + 1 + 2n + 3 + 2n + 5 = 51
⇒ 6n + 9 = 51
⇒ 6n = 42
⇒ n = 7
To find the values of the integers, substitute the found value of n into the expressions:
First integer: 2(7) + 1 = 15Second integer: 2(7) + 3 = 17Third integer: 2(7) + 5 = 19Therefore, the three consecutive odd integers that sum to 51 are 15, 17 and 19. The smallest of which is 15.
can someone please explain how to factor a polynomial. {will mark as brainliest}
To factorize a polynomial you need to find the zeros, and then you can write the polynomial as a product of bynomials.
How to factor a polynomial?
For a polynomial of the form:
[tex]p(x) = A_n*x^n + A_{n-1}*x^{n-1} + ... + A_1*x + A_0[/tex]
We define the zeros as the values of x such that:
p(x) = 0.
On the above case, the degree of the polynomial is n (the maximum exponent). Then the number of zeros of the polynomial is n (same as the degree).
Once we know the n zeros, we can factorize the polynomial as:
[tex]p(x) = A_n*(x - x_1)*(x - x_2)*...*(x - x_n)[/tex]
For example, for the polynomial:
[tex]p(x) = 2x^2 - 8[/tex]
The two zeros are x = 2 and x = -2, then it can be rewriten as:
[tex]p(x) = 2*(x + 2)*(x - 2)[/tex]

Find Median of 10,12,14 and 16
Step-by-step explanation:
the median is the value, where half of the other values is smaller (or equal), and the other half bigger (or equal).
with an even number of data points that is not directly possible to find.
in this case the 2 middle values are taken and their mean value is the median.
in our case, the 2 middle values are 12 and 14.
their mean value is
(12+14)/2 = 26/2 = 13
so,
13 is the median (even though if is not a data point itself).
