Hope this helps!!!!
Need help ASAP!!!!!
Answer:
cos 45 degree = A/H
cos 45 degree = 2 square root 2 / x
x = 2 square root 2 / cos 45 degree
x = 4
Sin 45 degree = O/H
Sin 45 degree = y/ 4
4 x Sin 45 degree = y
y = 2.83
or
we could use tan
tan 45 degree = O/A
tan 45 degree = y / 2 square root 2
2 square root 2 x tan 45 degree = y
y = 2.83
i hope this would elp a little bit.
Solve for x. x^2 + 4x + 4 = 8

Write the equation in standard form for the circle x^2 + y^2 - 14y + 24 = 0
Answer:
x^2+(y-7)^2=25
Step-by-step explanation:
x^2+y^2-14y=-24
x^2+(y-7)^2-49=-24
x^2+(y-7)^2=25
Use slope-intercept form to write an equation of a line passing through the given point and having the given slope. Express the answer in standard form.
P(−4, −6); m = −3/4
9514 1404 393
Answer:
3x +4y = -36
Step-by-step explanation:
The slope-intercept form is ...
y = mx + b
where m is the slope and b is the y-intercept. From this equation, we can find the y-intercept as ...
b = y -mx
For the given point and slope, this is ...
b = -6 -(-3/4)(-4) = -9
Then the slope-intercept equation is ...
y = -3/4x -9
We can multiply by 4 to get something we can put in standard form.
4y = -3x -36
3x +4y = -36 . . . . standard form equation

On a time crunch!!!!!
Answer: x = 0
Step-by-step explanation:
Subtract 6x^3+29x^2+47x+28 from both sides:
(2^2 + x + 4) (x - 7) - 6x^3+29x^2+47x+28
(6x^3+29x^2+47x+28)-6x^3+29x^2+47x+28
= -4x^3 - 14x^2 - 36x = 0
Now factor the left side:
-4x^3 - 14x^2 - 36x = 0
(-2x) (2x^2 + 7x + 18) = 0
Now set the factors equal to 0
-2x = 0 or 2x^2 + 7x + 18 = 0
x = 0

this stuff is kinda hard please help me find the answer
Answer: 1 is D and 2 is B I think
Step-by-step explanation: 1 is D because 59.2 + (-84.7) because D is the same thing as 59.2-84.7, just written differently. 2 is B because the longer line resembles -15 and the smaller line resembles 6. -9 is circled because its supposed to add up to -9, hence why it would be 6+(-15)=-9. Hope this helped :)

Find the value of x. Pythagorean theorem and its converse
Tell me the Definition of each Word listed (math)
Determine whether the value is a discrete random variable, continuous random variable, or not a random variable. a. The number of textbook authors now sitting at a computer b. The height of a randomly selected giraffe c. The responce to the survey question "Did you smoke in the last week" d. The amount of rain in City B during April e. The time it takes to fly from City A to City B f. The number of light bulbs that burn out in the text week in a room with 17 bulbs a. Is the a discrete random variable, a continuous random variable, or not a random variable? A. It is a random variable. B. It is a random variable. C. It is not a random variable.
Answer:
Discrete variables are those whose distribution will only take a finite number of values which are represented by integer values only.
Continous variables on the other hand could have an infinite number of points inbetween two integer values. With the values inbetween being decimals.
Step-by-step explanation:
a. The number of textbook authors now sitting at a computer :
A discrete random variable
Number of authors will be an integer value.
b. The height of a randomly selected giraffe ;
Continous random variable
Possible height value : h > 0
c. The responce to the survey question "Did you smoke in the last week"
It is not a random Variable
The response isn't numeric
d. The amount of rain in City B during April
It is a continous random variable
Possible values ; amount of rain > 0
e. The time it takes to fly from City A to City B
It is a continous random variable
Time could take up seconds value ;
Possible values : t > 0
f. The number of light bulbs that burn out in the text week in a room with 17 bulbs
It is a discrete random variable
Number of bulbs is defined

The hanger shown in the diagram is balanced. Both cherries weigh the same, both mushrooms
weigh the same, both carrots weigh the same, and all three strawberries weigh the same.
How many grams does the exotic fruit weigh if the total weight of all ten items is 84 grams?
Answer:
The mass of the exotic fruit is 20 grams.
Step-by-step explanation:
For the system to be in equilibrium,
i. the resultant of all masses must be zero
ii. the total mass on the left of the hanger must be equal to that on the right
Thus,
84 g = 42 g + 42 g
mass of each carrot = 12 g
mass of each mushroom = 10 g
mass of each cherry = 2.5 g
mass of each strawberry = 5 g
So that;
On the left of the hanger,
(2 x 5) + (2 x 10) + 12 = 42
10 + 20 + 12 = 42
42 = 42
On the right of the hanger, let the mass of exotic fruit be represented by x.
x + 12 + 5 + (2 x 2.5) = 42
x + 12 + 5 + 5 = 42
x + 22 = 42
x = 20 g
The mass of the exotic fruit is 20 grams.
The equation x = 1 is an example of linear but not function. Why?

Determine if the matrix below is invertible. Use as few calculations as possible. Justify your answer. Choose the correct answer below. A. The matrix is not invertible because its determinant is zero. B. The matrix is invertible because its determinant is not zero. C. The matrix is not invertible because the matrix has 2 pivot positions. D. The matrix is invertible because its columns are multiples of each other. The columns of the matrix form a linearly dependent set.
Answer:
A. The matrix is not invertible because its determinant is zero.
Step-by-step explanation:
The matrix is invertible if the columns and rows are equal. The square matrix is invertible because it has equal rows and columns. The determinant of the matrix is zero then the matrix is no invertible.

There are 90 million pet dogs in the US. The number of dogs is 1000% the number of reptiles. How many reptiles are there?
Answer:
There are 9 000 000 = 9 million reptiles in the US.
Step-by-step explanation:
Percentages and ratio:
The double of a measure, for example, is 200% of the measure.
So 1000% of a measure is 10 times the measure.
There are 90 million pet dogs in the US. The number of dogs is 1000% the number of reptiles.
The number of pet dogs is 10 times the number of reptiles, which means that:
[tex]10x = 90 000 000[/tex]
[tex]x = \frac{90 000 000}{10}[/tex]
[tex]x = 9 000 000[/tex]
There are 9 000 000 = 9 million reptiles in the US.
