Which set of measurements makes it possible to draw a unique triangle?
A
two angle measures of 30° and 55
B
two side measures of 6 ft and 15 ft
two side measures of 15 ft and 10 ft, and a non-included angle measure of 25°
D
two angle measures of 35 and 50 and a non-included side measure of 7 ft

Used to coordinate gird plane to find a distance between the points round to the nearest hundred
Answer:
8.94
Step-by-step explanation:
Distance formula:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex]
[tex]d = \sqrt{(3 - (-5))^2 + (2-6)^2}[/tex]
[tex]d = \sqrt{(64 + 16)}[/tex]
[tex]d= \sqrt{80}[/tex]
[tex]d= 8.94[/tex]

Quadratic Formula:
ax² + bx + c = 0Substitute 1 for a, -2 for b, and -8 - y for c in the quadratic formula.
Answer:
[tex]y= (x-4)(x+2)[/tex]
Step-by-step explanation:
To factor polynomials you have to use FOIL. Which stands for First, Outer, Inner, and Last. This means that you have to multiply the first numbers of each part by each other, the outer two between both parts, the inner two between both parts, and the last two of each part, respectively. Then, you would simplify. If you go and do this for each answer choice, the last one would be the only correct one.

Answer: the 2nd box
Step-by-step explanation:
the coordinates of the points A and B are (0,-2) and (3,0), what is the y intercept of the line AB
Answer:
The y-intercept of points A and B is -2.
Step-by-step explanation:
Point A is the y-intercept. You can tell by looking at the x and seeing that it is 0. This means the point is the y-intercept.
Hope this helps!
-Luna
Answer:
-2
Step-by-step explanation:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis). To solve this question, first, find the slope, then, plug one of the given points into the equation to isolate b.
1) Find the slope (m)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the given points (0,-2) and (3,0)
[tex]m=\frac{0-(-2)}{3-0}\\m=\frac{0+2}{3}\\m=\frac{2}{3}[/tex]
Therefore, the slope of of the line is [tex]\frac{2}{3}[/tex]. Plug this into [tex]y=mx+b[/tex] as m:
[tex]y=\frac{2}{3} x+b[/tex]
2) Find the y-intercept (b)
[tex]y=\frac{2}{3} x+b[/tex]
Plug in one of the given points: (0,-2) or (3,0)
[tex]0=\frac{2}{3} (3)+b\\0=2+b\\b=-2[/tex]
Therefore, the y-intercept of the line AB is -2.
I hope this helps!
If a triangle has sides with lengths of 10 inches 12 inches and 14 inches is a right triangle?
Answer:
not a right triangle
Step-by-step explanation:
right triangles are those that prove out to be true when you square the two smaller sides and the sum is equal to the square of the longest side
true or false?
10² + 12² = 14²
100 + 144 = 196
False, ∴ not a right triangle
Kaj has a bag that contains pineapple chews, cherry chews, and peach chews. She performs an experiment. Kaj randomly removes a chew from the bag, records the result, and returns the chew to the bag. Kaj performs the experiment 24 times. The results are shown below:
A pineapple chew was selected 17 times.
A cherry chew was selected 5 times.
A peach chew was selected 2 times.
Based on these results, express the probability that the next chew Kaj removes from the bag will be peach chew as a fraction in simplest form.

ps. use photomath on phone
Write both number with the same power of 10, factor out that power of 10 (since it's common to both terms), then simplify to standard scientific notation (that is, a.bcd... × 10⁻ⁿ):
(8.28 × 10⁻⁵) - (4.1 × 10⁻⁷) = (828 × 10⁻⁷) - (4.1 × 10⁻⁷)
… = (828 - 4.1) × 10⁻⁷
… = 823.9 × 10⁻⁷
… = 8.239 × 10⁻⁵

Use the distance formula to find the distance between each pair of points round to the nearest 10th if necessary
Given:
The pairs of points are:
a. A(-6,-4), B(-3,-1)
b. C(3.5,1), D(-4,2.5)
c. X(5,-5), Y(-5,5)
To find:
The distance between the pair of points by using the distance formula.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
a.
Using the distance formula, the distance between the points A(-6,-4) and B(-3,-1) is:
[tex]AB=\sqrt{(-3-(-6))^2+((-1-(-4))^2}[/tex]
[tex]AB=\sqrt{(3)^2+(3)^2}[/tex]
[tex]AB=\sqrt{2(3)^2}[/tex]
[tex]AB=3\sqrt{2}[/tex]
[tex]AB\approx 4.2[/tex]
Therefore, the distance between the points A(-6,-4) and B(-3,-1) is about 4.2 units.
b.
Using the distance formula, the distance between the points C(3.5,1) and D(-4,2.5) is:
[tex]CD=\sqrt{(-4-3.5)^2+(2.5-1)^2}[/tex]
[tex]CD=\sqrt{(-7.5)^2+(1.5)^2}[/tex]
[tex]CD=\sqrt{56.25+2.25 }[/tex]
[tex]CD=\sqrt{58.5 }[/tex]
[tex]CD\approx 7.6[/tex]
Therefore, the distance between the points C(3.5,1) and D(-4,2.5) is about 7.6 units.
c.
Using the distance formula, the distance between the points X(5,-5) and Y(-5,5) is:
[tex]XY=\sqrt{(-5-5)^2+(5-(-5))^2}[/tex]
[tex]XY=\sqrt{(-10)^2+(10)^2}[/tex]
[tex]XY=\sqrt{100+100}[/tex]
[tex]XY=\sqrt{200}[/tex]
[tex]XY\approx 14.1[/tex]
Therefore, the distance between the points X(5,-5) and Y(-5,5) is about 14.1 units.

Which of the following is closest to the circumference, in inches, of a circle that has a diameter of 12 inches?
Answer:
37.68 inches
Step-by-step explanation:
The formula for the circumference of a circle is 2πr.
The radius is 6, and 6⋅2 = 12 (diameter).
3.14 = pi.
12 ⋅ 3.14 = 37.68
Whichever answer is closest to 37.68 is your answer!

-0.01 (65)+110 = 109.35
It was the predicted value of the 65 year old's vision score.
Since the equation has an equal sign
y (=)
And not more than nor less than, answer choices C and D are eliminated.
The exact value for the 65 year old's vision score is 102. So, A isn't right.
