The terminal side of an angle θ in standard position is in quadrant 1. If sinθ=0.8, find cosθ.
Answer:
[tex]cos\theta=\frac{3}{5}[/tex]
Step-by-step explanation:
Since [tex]sin\theta=0.8[/tex] is the same as [tex]sin\theta=\frac{4}{5}[/tex] and [tex]sin\theta=\frac{opposite}{hypotenuse}[/tex], then we know that the side opposite to the angle [tex]\theta[/tex] is 4 units and the hypotenuse is 5 units.
Because [tex]cos\theta=\frac{adjacent}{hypotenuse}[/tex], then we have to find the adjacent side to the angle [tex]\theta[/tex] using the Pythagorean Theorem:
[tex]a^2+b^2=c^2\\\\(adjacent)^2+(opposite)^2=(hypotenuse)^2\\\\(adjacent)^2+4^2=5^2\\\\(adjacent)^2+16=25\\\\(adjacent)^2=9\\\\adjacent=3[/tex]
Therefore, since the adjacent side is 3 units, then [tex]cos\theta=\frac{3}{5}[/tex]

a standard deck of cards missing the queen of hearts in the 2 of clubs what is the probability of pulling either an ace or a spade
=======================================================
Explanation:
In a standard deck, there are 52 cards.
If this deck is missing the queen of hearts and 2 of clubs, then we really have 52-2 = 50 cards in the deck.
There are 4 aces and 13 spades. Those values add to 4+13 = 17, but we need to subtract off 1 to account for the ace of spades counted twice. We have 17-1 = 16 cards that are either an ace, a spade, or both.
Or you can think of it like saying 13 spades + 1 ace of hearts + 1 ace of diamonds + 1 ace of clubs = 16 cards total.
-----------------
The event space has A = 16 cards in it, while the sample space has B = 50 cards.
The probability we're after is A/B = 16/50 = 8/25

Step-by-step explanation:
[tex] {5}^{3x} - {5}^{3x - 1} = 4 \\ \\ \implies{5}^{3x} - {5}^{3x} . {5}^{ - 1} = 4 \\ \\ \implies{5}^{3x}(1 - {5}^{ - 1} )= 4 \\ \\ \implies{5}^{3x} \bigg(1 - \frac{1}{5} \bigg)= 4 \\ \\ \implies{5}^{3x} \bigg(\frac{5 - 1}{5} \bigg)= 4 \\ \\ \implies{5}^{3x} \times \frac{4}{5} = 4 \\ \\ \implies{5}^{3x} = 4 \times\frac{5}{4} \\ \\ \implies{5}^{3x} =5 \\ \\ \implies \: 3x = 1 \\ \\ \huge \implies \: x = \frac{1}{3} \\\\ \huge \implies \: x = 0.33[/tex]

Matthew can spend up to $75 on supplies for his garden. The flowers will cost $38 and he wants to spend the rest on bags of top soil. Each bag of top soil costs $6.
How many bags of top soil can he buy?
Answer:
6 bags.
Step-by-step explanation:
Subtract 38 from 75 to represent the remaining amount of Matthew's money.
[tex]75-38=37.[/tex]
Matthew has $37 left over from buying flowers.
Divide 37 by 6 to represent how many bags of soil he can buy.

Matthew can only buy 6 bags of soil, 1/6 isn't included because you can't buy a fraction of a bag.

Ebony put 10 cubes into two stacks. One stack has 4 more cubes than than the other stack. How many cubes are in each stack? Show your work.
Answer:
Step-by-step explanation:
10 cubes ÷2 stacks = 5, so in each stack 5.
one stack has 5
Second stack has 4 more cubes than the other. (5+4=9)
So the answer is 5 and 9
The number of cubes is 3 and 7 in two stacks consisting of 10 stacks total.
Suppose Ebony has 'x' cubes in one stack
So, the number of cubes in another stack =x+4
What is a cube?A cube is a solid having all three dimensions i.e. length, breadth, and height equal to each other.
According to the question,
Total number of cubes = 10
x+(x+4) = 10
2x+4 =10
2x=6
x=3
So, Ebony has 3 cubes in one stack
Number of cubes in another stack =3+4 =7cubes
Therefore, The number of cubes is 3 and 7 in two stacks consisting of 10 stacks total.

You must also write the linear equation used to solve the problem. The memory card in Carla's camera can hold 1,024 pictures. On April 30th, Carla sees that she has 235 pictures on the memory card. She plans to take 35 pictures each day in the month of May. How many pictures will Carla have on the memory card on May 16th? On what day will the memory card be full?
Carla would have about 795 pictures on May 16th.
Linear equationA linear equation is in the form:
y = mx + b
where y,x are variables, m is the rate of change and b is the y intercept.
Let y represent the number of pictures after x days.
At April 30th, Carla sees that she has 235 pictures, hence b = 235. Also, she takes 35 pictures each day, hence m = 35. The equation is:
y = 35x + 235
On May 16th, x = 16 hence:
y = 35(16) + 235 = 795
Carla would have about 795 pictures on May 16th.

f(-2) = 16 + 4 + 1
f(-2) = 21

Check whether this is a quadratic equation or not ...
=>>>>> x²-2x = (-2)(3-x)
Answer:
yup it is ...
x²-2x = -6+2x
=> x²-4x +6
By expanding the equation, we can see that it is quadratic.
Is the equation quadratic?
A quadratic equation is any polynomial of degree 2.
Here we have:
x^2 - 2x = (-2)*(3 - x)
Expanding this we get:
x^2 - 2x = -6 + 2x
Moving all to the same side:
x^2 - 2x - 2x + 6 = 0
x^2 - 4x + 6 = 0
This is a polynomial of degree 2, so this is a quadratic equation.

Answer:
B
Step-by-step explanation:
From inspection of the box plot:
Minimum value = 24Maximum value = 34Lower quartile [tex](Q_1)[/tex] = 27Upper quartile [tex](Q_3)[/tex] = 33Median [tex](Q_2)[/tex] = 31The median is the middle number in a sorted (ascending or descending) list of numbers. All the numbers in each data set. are sorted in ascending order. Data sets C and D have medians of 30, so we can discount them.
The maximum value on the box plot is 34. Therefore, we can discount option A, since its max value is 35.
Therefore, the answer is option B.
Futher checking with quartiles:
The lower quartile is the value at the first quarter. As there are 9 values per data set, the lower quartile will be the mean of the 2nd and 3rd values.
The upper quartile is the value which is three quarters of the way into the data set. As there are 9 values per data set, the upper lower quartile will be the mean of the 7th and 8th values.
Option B
lower quartile = (25 + 29)/2 = 27
upper quartile = (32 + 34)/2 = 33
This confirms that Option B is the final solution.
Find the x- and y -intercepts of the graph of the linear equation -6x+9y=-18 .
The x -intercept is
.
The y -intercept is
.
Answer:
The x -intercept is (3, 0)
The y -intercept is (0, - 2)
Step-by-step explanation:
Given equation is: -6x + 9y = -18
To find x - intercept:
Plug y = 0 in the given equation.
-6x + 9(0) = - 18
-6x + 0 = -18
-6x = - 18
x = (-18)/(-6)
x = 3
The x -intercept is (3, 0)
To find y - intercept:
Plug x = 0 in the given equation.
-6(0) + 9y= - 18
0 + 9y = -18
9y = - 18
y = (-18)/(9)
y = - 2
The y -intercept is (0, - 2)
