Answer:
$66.00
Step-by-step explanation:
first we need multiply :D I will use the formula I =prt
principal= $500
rate=3.3%
time= 4 years
but we need to convert the percent, 3.3%, to a decimal
3.3%=0.033 or .033
now we multiply !
500 × 0.033 × 4 = 66 = $66.00
If tanΘ = 6/5 and cosΘ < 0, what is sin2Θ?
An explanation on how to solve this problem would be great, thanks!!
Answer:
[tex]\displaystyle \sin2\theta=\frac{60}{61}[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle \tan\theta=\frac{6}{5}\text{ and } \cos\theta <0[/tex]
And we want to find the value of sin(2θ).
First, recall that tangent is the ratio of the opposite side to the adjacent side.
Therefore, the hypotenuse is:
[tex]h=\sqrt{6^2+5^2}=\sqrt{61}[/tex]
Next, note that tangent is positive and cosine is negative. Tangent is positive in QI and QIII. Cosine is negative in QII and QIII.
Hence, we can conclude that θ must be in QIII.
In QIII, sine is negative, cosine is negative, and tangent is positive.
And with respect to θ, our opposite side is 6, adjacent side is 5, and the hypotenuse is √(61).
We can rewrite our expression as:
[tex]\sin2\theta=2\sin\theta\cos\theta[/tex]
Using the above information, substitute:
[tex]\displaystyle =2\left(-\frac{6}{\sqrt{61}}\right)\left(-\frac{5}{\sqrt{61}}\right)[/tex]
Simplify. Hence:
[tex]\displaystyle \sin2\theta=\frac{60}{61}[/tex]
i need to gina the length of the side

Find Y
A: 14.3
B: -6.3
C: 7.0
D: 11.6
Answer:
D
Step-by-step explanation:
Using the sine ratio in the right triangle
sin51° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{9}{y}[/tex] ( multiply both sides by y )
y × sin51° = 9 ( divide both sides by sin51° )
y = [tex]\frac{9}{sin51}[/tex] ≈ 11.6 ( to 1 dec. place ) → D
A teacher ask her pupils what there favorite school subject was 3 pupils said pe was there favorite subject how many pupil said maths was there favorite subject
I have added the complete question in the attachment
Answer:
15
Step-by-step explanation:
From the diagram in the attachment
27⁰ represents 3 pupils they love PE
135⁰ represents those that love mathematics. But the number was not given.
We have;
27⁰ = 3
135⁰ = ?
We cross multiply to find the unknown
135⁰x3 = 27⁰?
405 = 27⁰?
Divide through by 27
405/27 = ?
15 = ?
Therefore 15 pupils said mathematics was there favorite

Answer:
C) x = 3
Step-by-step explanation:
factor out a 2 to get:
2(x² - 6x + 9) = 0
(x-3)² = 0
x = 3
Answer and Step-by-step explanation:
First, to find the zeros of the function, we can take out a common factor from the equation, and then factor.
The equation has a common factor of 2 (so distribute of the 2 from all of the numbers).
2([tex]x^2 - 6x + 9[/tex])
Now, we factor. Find two numbers that multiplies to [tex]9x^2[/tex] and adds up to -6x.
-3x and -3x.
Now, we substitute these two for -6x.
[tex]2(x^2 - 3x-3x+9)[/tex]
Factor.
[tex]2(x - 3)(x-3)[/tex]
Finally, we set all of the values to 0 and solve for x.
2 ≠ 0
x - 3 = 0 x = 3
x - 3 = 0 x = 3
That means the answer is C. x = 3
(Not shown, but the multiplicity of this x value is 2, because there are two
x = 3)

On a coordinate plane, a parabola opens down. It has an x-intercept at (negative 5, 0), a vertex at (negative 1, 16), a y-intercept at (0, 15), and an x-intercept at (3, 0).
The function f(x) = –x2 − 2x + 15 is shown on the graph. What are the domain and range of the function?
The domain is all real numbers. The range is {y|y < 16}.
The domain is all real numbers. The range is {y|y ≤ 16}.
The domain is {x|–5 < x < 3}. The range is {y|y < 16}.
The domain is {x|–5 ≤ x ≤ 3}. The range is {y|y ≤ 16}
Answer:
the domain is xl-5<×< 3 is the range of 16
The domain is all real numbers. The range is {y|y ≤ 16}.
Domain of the functionThe domain of a function is all the of values of the input or independent variable into the function
Since the x-intercepts of the function are at (-5, 0) and (3, 0), and also, the graph opens downwards, the values of x are in the interval (-∞ ≤ x ≤ -5) ∪ (-5 ≤ x ≤ 3) ∪ (3 ≤ x ≤ ∞). This is (-∞ ≤ x ≤ ∞).
So, the domain is the set of all real numbers.
The range of a functionThe range of a function is all the output values of the function
Since the vertex of the parabola is at (-1, 16) and its y-intercept is at (0, 15), the maximum value of y is 16. So, the values of y are in the range y ≤ 16.
So, the range of the function is {y|y ≤ 16}
So, the domain is all real numbers. The range is {y|y ≤ 16}.

At George Washington High School, 119 students walk to school. If this number is 35% of school enrollment, then how many students are enrolled at the school ?
Answer: 340 students
Step-by-step explanation:
The number of students walking to school is 119 and this is 35% of the total number of students.
Assume the total number is denoted by "x".
That would mean that the following formula captures the situation:
119 = 35% * x
119 = 0.35x
x = 119/ 0.35
= 340 students

Janelle draws line segments AB and BC in the same plane such that AB = 8 cm and BC = 6 cm. Then Janelle draws
line segment AC.
Use this information to determine the length, in centimeters, of AC for the following two situations.
• AB, BC, and AC form a triangle. Enter a possible value of AC in the first response box.
• Points A, B, and C lie on the same line, and C lies between A and B. Enter this value of AC in the second
response box.
Answer:
Step-by-step explanation:
• AB, BC, and AC form a triangle. Enter a possible value of AC....
So it asks for only a possible value of AC as there are many possible values.
Given AB = 8 cm and BC = 6 cm, they are in the ratio of 3:4.
Line segments of 3, 4 and 5 length will form a right-angled triange.
A possible value of AC = 5*2 = 10cm
• Points A, B, and C lie on the same line, and C lies between A and B.
So AC+CB = AB
AC+6 = 8
AC = 2cm
Enter this value of AC in the second
response box.
Answer:
Step-by-step explanation:
if ABC forms a triangle, AB=8 and BC=6
a possible value of AC=10cm
if ABC is a line segment n C is between A n B
AC + BC = AB
AC = 8 - 6 = 2cm

A computer downloads a 48 kilobyte file in 5 seconds. At this rate, how long will it take the computer to download a file that is 120 kilobytes?
Answer:
12,5
Step-by-step explanation:
First, you need to find how many kilobytes do you download every seconds.
You simply divide 48 kilobyte / 5 seconds and you get 9,6 kB/s.
Now you know that your download speed is this you can find the amount of time needed for downloading 120 kilobytes.

A 17-foot ladder is leaning against a building. The base of the ladder is 8 feet
from the base of the building. The side of the building and the ground form
a right angle as shown.
Enter the distance between the ground and the top of the ladder, x, in feet.
Answer:
Pythagorean theorem:
x^2 = 17^2 - 8^2
x^2 = 225
x = sqrt(225) = 15
The distance is 15 ft
Answer:
Solution given:
base=8ft
hypotenuse=17ft
perpendicular=?
By using Pythagoras law
hypotenuse ²=perpendicular ²+base²
17²=perpendicular ²+8²
perpendicular ²=17²-8²
perpendicular=[tex]\sqrt{225}=15[/tex]
