Answer:
about 7.3 units
Step-by-step explanation:
to find the answer you do Pythagorean theorem
so you have (-9, -4) and (-2, -6)
you do X1-X2 and Y1-Y2
so -4-(6)=2
and -9-(-2)= -7
now you do a^2 + b^2 = C^2
so 2^2 + -7^2 = C^2
which is 4 + 49= C^2
53=C^2
√53=7.3
so 7.3 units :)

Find the value of X and Y write your answer in simplest form does anyone know how to
Answer:
5 = y
7.1 = x
Step-by-step explanation:
(There are so many ways we can solve this, let's solve this the easiest way):
Let's solve for y first =
We can say;
Tan(45) = y/5
Tan(45) * 5 = y
1 * 5 = y
5 = y
Now let's solve for x;
5² + y² = x²
5² + 5² = x²
25 + 25 = x²
50 = x²
[tex]\sqrt{50\\}[/tex] = x
7.1 = x
Hope this helps!

Okay, I'm gonna name this triangle XYZ.
An isosceles triangle is when two sides are equal. We know that an area of a triangle is always 180 degrees. A right triangle always has one degree of 90 degrees. We know that y∠45, x∠90, so z has to be 45 as well. We know this is a right isosceles triangle due to the angles it has given us.
Now, we know y and z are the same sizes. y=z
using the Pythagorean theorem
take a square root of sums of squares [tex]x=y^2+z^2[/tex]
[tex]5^2=25[/tex]
25+25=50

Answer:
n = - [tex]\frac{4}{7}[/tex]
Step-by-step explanation:
Given
[tex]\frac{2}{3}[/tex] (1 + n) = - [tex]\frac{1}{2}[/tex] n
Multiply both sides by 6 ( the LCM of 3 and 2 ) to clear the fractions
4(1 + n) = - 3n ← distribute left side
4 + 4n = - 3n ( add 3n to both sides )
4 + 7n = 0 ( subtract 4 from both sides )
7n = - 4 ( divide both sides by 7 )
n = - [tex]\frac{4}{7}[/tex]

let assume the number is x:
Therefore 2x - 5
Rewrite the equation of the line in slope intercept form.
4x−8y=32
Answer:
y=1/2x-4
Step-by-step explanation:
subtract 4x from the left side and the right side. It becomes:
-8y=-4x+32
divide -8 from both sides and it becomes:
y=1/2x-4

Answer:
(a) 0.6
(b) 0.4
Step-by-step explanation:
If I am reading the little table right, You have made 9 shots, and have missed 6 of them. Therefore, in total, you have made [tex]9+6=15[/tex] shots.
The definition of probability is the number of events of a desired outcome divided by the total number of outcomes. Since you wish to make a shot for part a, the number of desired outcomes thus far is 9, out of 15 total shots. Thus,
[tex]P([/tex]making a shot[tex])=\frac{9}{15}=\frac{3}{5}=0.6[/tex]
Since making a shot and not making a shot are mutually exclusive events, and the only two events that could occur when shooting a basket, the probability of not making a shot and the probability of making a shot are all of the possible outcomes, and is thus equal to 1.
[tex]P([/tex]making a shot[tex])+P([/tex]missing a shot) [tex]=1[/tex]
[tex]P([/tex]missing a shot[tex])=1-P([/tex]making a shot[tex])[/tex]
[tex]P([/tex]missing a shot[tex])=1-0.6=0.4[/tex]

Blake has 864 square inches of material with which to create a hollow three-dimensional container. He decides to make either a cube or a sphere.
Which solid would have the greater volume? What is the greatest volume he can achieve with this amount of material?
Answer:
I think it's a cube, because the cube has bigger spaces because of the edges, but I don't know how much...
The relationship between the length and weight of certain sea turtles can be approximated by the equation L = 0,55 W,
where L is the length in feet and W is the weight in pounds. If a sea turtle is 2.5 feet long, which is closest to its weight?
Answer:
4.55 pounds
Step-by-step explanation:
From the above question , we are told that:
The relationship between the length and weight of certain sea turtles can be approximated by the equation
L = 0.55 W,
where
L is the length in feet
W is the weight in pounds. If a sea turtle is 2.5 feet long, which is closest to its weight?
L = 2.5 feet
Hence,
2.5 = 0.55W
W = 2.5/0.55
W = 4.5454545455 pounds
Approximately, weight of the sea turtle in pounds = 4.55 pounds

What is the domain of the function Y = tan(x/8)?
Oall real numbers except 4pi+4npi where n is any integer
Oall real numbers except 4pi+8npi where n any integer
Oall real numbers except 8pi+4npi, where n is any integer
Oall real numbers except 8pi+8npi, where n is any integer
Answer:
B) all real numbers expect 4pi+8pi where n is any integer
Step-by-step explanation:
The domain of the function y = tan(x/8) is given by: All real numbers except 4π+8nπ , where n is any integer.
What is the domain of a function?The domain is the set that contains all possible input values for the function.
Since we know that Tangent of an angle is sine of the angle divided by the cosine of the angle, and the cosine is 0 at:
π/2 + nπ
Hence, let a composite tangent function , the domain is given by:
f(x) does not equal to π/2 + nπ
we have that , hence the domain is:
all real numbers except 4π+8nπ
All real numbers except 4π+8nπ, where n is any integer.

F is inversely proportional to d^2.
When F = 5, d = 9
Work out d (positive value rounded to 2 DP) when F = 3
Answer:
11.6
Step-by-step explanation:
F = k/ d^2
where k = proportionality constant
k = Fd^2
k = 5 * 9^2
k = 5*81 = 405
d = (K/F)^1/2
d = (405/3)^1/2
d = 11.62 =11.6
Answer:
11.62
Step-by-step explanation:
F is inversely proportional to d^2, so
[tex]F=\frac{k}{d^2}[/tex]
for some constant k. To find k plug in given values for F and d.
[tex]5=\frac{k}{9^2}\\5=\frac{k}{81}\\k=405[/tex]
Now you can find d for F = 3.
[tex]3=\frac{405}{d^2}\\\\3d^2=405\\\\d^2=135\\d=\sqrt{135}\approx 11.62[/tex]
Ned types 360 words in 6 minutes. Nate types 220 words in 4 minutes.
Who would type more words in 10 minutes? What assumptions do you
make?
Answer and step-by-step explanation:
We know that Ned types 360 words in 6 minutes while Nate types 220 words in 4 minutes. We are then asked to find out who would type more words in 10 minutes.
To solve this, we need to first reduce the fraction of how many words can be typed to a certain amount of minutes to find how many minutes exactly can Ned and Nate type in one single minute.
Ned types 360 words in 6 minutes, our fraction would be :
[tex]\frac{360}{6}[/tex]
Nate types 220 words in 4 minutes, our fraction would be :
[tex]\frac{220}{4}[/tex]
Now divide both sides by their LCM :
Ned:
[tex]\frac{360/6}{6/6}[/tex]
Nate:
[tex]\frac{220/4}{4/4}[/tex]
Ned :
[tex]\frac{60}{1}[/tex]
Nate:
[tex]\frac{55}{1}[/tex]
This means that in one minute, Ned can type 60 words while Nate can type 55 words. Since we know that 60 is a greater number than 55, we can assume that Ned will type more words than Nate in 10 minutes.
Two forces, one of 45 pounds and the other 50 pounds, act on the same object. The angle between the forces is 33°. Find the magnitude of the resultant vector. Pls help :( cant afford to fail
Answer:
The magnitude of the resultant force is: 27.40 pounds
Step-by-step explanation:
Given
[tex]F_1 = 45[/tex]
[tex]F_2 = 50[/tex]
[tex]\theta = 33[/tex]
Required
The magnitude of the resultant vector
To do this, we apply cosine formula
[tex]R^2 = F_1^2 + F_2^2 - 2 * F_1 * F_2 * \cos(\theta)[/tex]
This gives:
[tex]R^2 = 45^2 + 50^2 - 2 * 45 * 50 * \cos(33)[/tex]
[tex]R^2 = 2025+ 2500 - 4500* 0.8387[/tex]
[tex]R^2 = 2025+ 2500 - 3774.15[/tex]
[tex]R^2 = 750.85[/tex]
Take square roots of both sides
[tex]R = \sqrt{750.85\\[/tex]
[tex]R = 27.40[/tex]
