Answer:
[tex]y=-5x+39[/tex]
Step-by-step explanation:
Hi there!
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x is 0)
1) Plug in the slope (m)
[tex]y=mx+b[/tex]
Plug in the slope -5
[tex]y=-5x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=-5x+b[/tex]
Plug in the given point (7,4) and solve for b
[tex]4=-5(7)+b\\4=-35+b[/tex]
Add 35 to both sides to isolate b
[tex]4+35=-35+b+35\\39=b[/tex]
Therefore, the y-intercept is 39. Plug this back into [tex]y=-5x+b[/tex]:
[tex]y=-5x+39[/tex]
I hope this helps!

Answer:
-5 + 3i √3
Step-by-step explanation:
Here, we want to get the value of uv
we have this as follows;
1( 1 + 2i √3) + i √3( 1 + 2i √3) ( i is same as square root of -1, so two roots of this will give the number we are looking for
= 1 + 2i √3 + i √3 + (2i)(i)(3)
= 1 + 3i √3 - 6
= 3i√ 3 -5

Answer:
Number of Cents = 10x
Step-by-step explanation:
Since w
Since we know that there are 10 cents in a dime, the amount of cents in an unknown quantity of dimes is 10 * the number of dimes.
Therefore the number of cents in x dimes is 10x

15 points please explain it to me add the answer and the work since I’m so confused on when to subtract missing lengths where and when
You didn't specify what the question was. However, I am going to assume you are looking for the missing side of the shape.
Let's call the left side "Side A" and the right side "Side B". One is longer than the other side. In this case, Side B is longer than Side A. To find the missing length, you will need to subtract Side A from Side B
Side B - Side A = Missing side
16 - 13 = 3
Therefore, the length of the missing side is 3.

Can someone give me the answer ?!?
Answer:
25%
Step-by-step explanation:
Probability = # of favorable outcomes / possible outcomes
favorable outcomes is what we want to happen ( throwing more than 3 pitches )
So to find the # of favorable outcomes we must find the frequency that the pitcher throws more than 3 pitches ( note: frequency of throwing 3 pitches is not included)
There are two possible outcomes of the pitcher pitching more than 3 pitches, 4 pitches having a frequency of 15, and 5 pitches which has a frequency of 10
So # of favorable outcomes = 10 + 15 = 25
Now we want to find the # of possible outcomes.
To do so we simply add the frequencies of each possible outcome.
15 + 20 + 40 + 15 + 10 = 100
So there are a total of 100 possible outcomes
Finally to find the probability of the pitcher throwing more than 3 pitches we divide favorable outcomes ( 25) by possible outcomes (100)
Our answer = 25/100 which can be converted into a percentage as 25%

Can’t find an answer anywhere pls help <3
Step-by-step explanation:
Consider the expression below:
[tex] \frac{10 - \sqrt{18} }{ \sqrt{2} } [/tex]
Note that there is a radical in the denominator so we need to eliminate it by multiplying and dividing it with the same radical:
[tex] \frac{10 - \sqrt{18} }{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } = \frac{10 \sqrt{2} \: - \: 6}{2} = - 3 + 5 \sqrt{2} [/tex]
By inspection, we can see that
a = -3 and b = 5
Answer:
[tex]a = - 3[/tex]
[tex]b = 5[/tex]
Step-by-step explanation:
Objective: Knowldge of Rationalizing Rational Functions.
Complete the LHS to find a and b.
Given
[tex] \frac{10 - \sqrt{18} }{ \sqrt{2} } = a + b \sqrt{2} [/tex]
Rationalize the LHS.
[tex] \frac{10 - \sqrt{18} }{ \sqrt{2} } \times { \frac{ \sqrt{2} }{ \sqrt{2} } } [/tex]
You'll get
[tex] = 5 \sqrt{2} - 3[/tex]
Flip is equation around.
[tex] - 3 + 5 \sqrt{2} [/tex]
This means that a equal -3 and b equal 5.

Step-by-step explanation:
If given lines are parallel, their slope must be equal. Therefore, the slope of the red line is also -2.
a) There are 15 teachers in a school and 10 of them are male teachers. i) Find the ratio of the number of male and female teachers. (ii) Find the ratio of the number of female teachers and the total number of teachers. One of the angles of a pair of complementary angles is 50°. Find the ratio of the pair of complementary angles.
Answer:
i) 2:1
ii) 1:3
iii) 5:4
Step-by-step explanation:
i) Male teachers : Female teachers
10 : 15-10
10 : 5
2 : 1
ii) Female teachers : Total teachers
5 : 15
1 : 3
iii) Do remember that two angles are called complementary if their measures add to 90 degrees.
Hence, ration of the pair of complementary angles = 50 : 90-50
= 50 : 40
= 5 : 4
Answer:
Step-by-step explanation:
Total number of teachers = 15
Given number of male teachers = 10
Therefore number of female teachers = 15 - 10 = 5
i)
Ratio of male and female teachers
[tex]\frac{male}{female} = \frac{10}{5} = \frac{2}{1}\\\\Ratio = 2 : 1[/tex]
ii)
Ratio of female teachers and total number of teachers
[tex]\frac{female}{total\ teachers} = \frac{5}{15} =\frac{1}{3} \\\\Ratio = 1 : 3[/tex]
iii)
If x and y are complementary angles, then x+ y = 90°
Given : one angle, x = 50°
Therefore, 50° + y = 90°
y = 90 - 50 = 40°
Ratio of the pair of complementary angles
[tex]\frac{x}{y} = \frac{50}{40} = \frac{5}{4} \\\\Ratio = 5 : 4[/tex]

Suppose 0 is an angle in the first quadrant and cos(0) = 1 What is the value of sin(0)?
Answer:
Step-by-step explanation:
I'm going to use a Pythagorean identity to help make this make sense.
[tex]sin^2\theta+cos^2\theta=1[/tex]
We are given that cos(0) = 1, so
cos²θ = 1² which simplifies to
cos²θ = 1. So filling into our trig identity:
sin²θ + 1 = 1 and
sin²θ = 0 then
sinθ = √0 so
sinθ = 0
[tex]sin^{-1}\theta=0[/tex] so
sin(0) = 0
10.)A child-sized swimming pool can be modeled by a cylinder. The pool has a diameter of 6 1/2 feet and a height of 12 inches. The pool is filled with water to 2/3 of its height. Determine and state the volume of the water in the pool, to the nearest cubic foot. One cubic foot equals 7.48 gallons of water. Determine and state, to the nearest gallon, the number of gallons of water in the pool.
Answer:
165.47≈165 Gallons of Water
Step-by-step explanation:
According To the Question,
Given, A child-sized swimming pool can be modeled by a cylinder. The pool has a diameter of 6 1/2 feet (or) 6.5 feet (radius is 3.25 feet) and a height of 12 inches(1 feet).The pool is filled with water to 2/3 of its height (H= 2/3 feet) .
Volume of Cylinder = π×R²×H , now put values, we get
Volume = 3.14×3.25²×2/3
Volume = 22.122 foot³ .
And, One cubic foot equals 7.48 gallons of water
Thus, 22.122 cubic foot equals to 165.47≈165 gallons of water .
