Which numbers complete the blanks when solving the equation cos(x+2pi)= -(square root of 2/2) over the interval [0, 2pi]?
Answer:
1, 0
Step-by-step explanation:
Let [tex]\cos (x+2\pi) = -\frac{\sqrt{2}}{2}[/tex]. From Trigonometry we remember the following identity:
[tex]\cos (a+b) = \cos a \cdot \cos b - \sin a \cdot \sin b[/tex] (Eq. 1)
Where [tex]a[/tex] and [tex]b[/tex] are angles measured in radians.
Then, we proceed to expand the given expression:
[tex]\cos x \cdot \cos 2\pi - \sin x \cdot \sin 2\pi = -\frac{\sqrt{2}}{2}[/tex]
[tex]\cos x \cdot 1 - \sin x \cdot 0 = -\frac{\sqrt{2}}{2}[/tex]
[tex]\cos x = -\frac{\sqrt{2}}{2}[/tex]
Therefore, correct answer is "1, 0".

Step-by-step explanation:
Summer got 12 multiple choice and four constructed response questions correct. Summer scored eight points more than Kerry who got 10 multiple-choice and three constructed response questions correct. Enter an equation that shows how much each multiple-choice question (m) and each constructed response question (c) is worth.
Answer: 2m + c =4
Step-by-step explanation:
Let m = Number of multiple-choice questions
c = Number of constructed response questions
For Summer,
Total marks = 12m + 4c
For kerry,
Total marks = 10m+3c
Summer scored eight points more than Kerry implies
12m + 4c = 4+(10m+3c)
⇒ 12m + 4c = 4+ 10m+3c
⇒ 12m + 4c - 10m-3c =4
⇒ 2m + c =4
Hence, required equation that shows how much each multiple-choice question (m) and each constructed response question (c) is worth. :
2m + c =4

Zane is planting an herb garden and goes to the garden center to buy plants. 18 of the plants
are rosemary plants, and 20 of the plants are plants of other types.
What is the probability that one plant randomly selected from the garden center will be a
rosemary plant? Write your answer as a fraction or whole number.
Answer:
P (rosemary) = 9/19
Step-by-step explanation:
Given :-
18 of the plants are rosemary20 plants are of other typesTo Find :-
Probability of selecting a rosemary plantSolving :-
Total No. of plants = 18 + 20 = 38 plantsP (rosemary) = No. of rosemary / No. of total plantsP (rosemary) = 18/38P (rosemary) = 9/19what's the answer to

Find the slope. Plot the points (-2,5) (1, 4).
Answer: y= 13/3−x/3
Step-by-step explanation:
The slope of a line passing through two points P=(x1,y1) and Q=(x2,y2) is given by m=y2−y1x2−x1.
We have that x1=−2, y1=5, x2=1, y2=4.
Plug the given values into the formula for a slope: m=4−(5)1−(−2)=−13.
Now, the y-intercept is b=y1−mx1 (or b=y2−mx2, the result is the same).
b=5−(−13)(−2)=13/3
Finally, the equation of the line can be written in the form y=b+mx:
y=13/3−x/3
Answer:

find the amount Anita borrowed from a finance company if she paid RS.3600 as interest for 3 years at 3% interest per annum.
Lets see
Interest=I=3600Rate of interest=R=3%Time=T=3yrsPrinciple=P[tex]\\ \rm\longmapsto I=\dfrac{PRT}{100}[/tex]
[tex]\\ \rm\longmapsto P=\dfrac{100I}{RT}[/tex]
[tex]\\ \rm\longmapsto P=\dfrac{360000}{9}[/tex]
[tex]\\ \rm\longmapsto P=Rs.40000[/tex]
Solution:
We know that:
Interest = ₹ 3,600Time = 3 yearsRate = 3%Let "P" represent the money Anita borrowed.
[tex]\dfrac{\text{P} \times 3 \times 3}{100} = 3,600[/tex]
[tex]\rightarrow \dfrac{\text{P} \times 9}{100} = 3,600[/tex]
[tex]\rightarrow \dfrac{\text{P} }{100} = 400[/tex]

Answer:
4. obtuse
5. obtuse
6. acute
7. acute
8. obtuse
Step-by-step explanation:
4. This angle is greater than a right angle (because it extends farther than one), so this is obtuse.
5. This angle is greater than a right angle, so this is obtuse.
6. This angle is smaller than a right angle (because it extends less than one), so this is acute.
7. This angle is smaller than a right angle, so this is acute.
8. This angle is greater than a right angle, so this is obtuse.

Alaska is the largest state in the United States. The state has an area of approximately 663,000 square miles. Rhode Island is the smallest state in the United States, with an area of approximately 1,000 square miles. Currently, the populations of Alaska and Rhode Island are 732,000 people and 1 million people, respectively. If Alaska had the same number of people per square mile as Rhode Island, what would its population be? In two or more sentences, explain your calculations and conclusions.
Answer:
663 Million people
Step-by-step explanation:
If you divide alaska into rhode island its 663 rhode islands in alaska, then theres 663 people in alaska fi the populations were the same

Answer:
[tex]k=6, k=-1[/tex]
Step-by-step explanation:
[tex]\dfrac{k+3}{3}-\dfrac{2}{k-5}=1[/tex]
[tex]\implies \dfrac{(k+3)(k-5)}{3(k-5)}-\dfrac{3 \cdot 2}{3(k-5)}=1[/tex]
[tex]\implies \dfrac{k^2-2k-15-6}{3(k-5)}=1[/tex]
[tex]\implies k^2-2k-21=3k-15[/tex]
[tex]\implies k^2-5k-6=0[/tex]
[tex]\implies (k-6)(k+1)=0[/tex]
[tex]\implies k=6, k=-1[/tex]

Suppose that a family wants to start a college fund for their child. if they can get a rate of 5.2%, compounded monthly, and want the fund to have a value of $55,500 after 20 years, how much should they deposit monthly? assume an ordinary annuity and round to the nearest cent. a. $131.93 b. $2,662.49 c. $1,643.30 d. $3,446.64
The ordinary annuity is $135.40
We have given that the
P=55500$
rate(r)=5.2%
time (t)=20 years
What is the formula for the ordinary annuity ?The formula for ordinary annuity is:
[tex]P = A \times \frac{((1 + r)^n- 1)}{ r}[/tex]
Where,P - future value
r - rate
A - annuity payment
n - the number of years
Use the given value in the above formula of ordinary annuity so we get,
[tex]55000 = A ((1 + 0.052)^{20} - 1) / 0.052[/tex]
[tex]55000 = A * ((1.052)^{20} - 1) / 0.052[/tex]
[tex]55000 = A * (2.76 - 1) / 0.052[/tex]
[tex]55000 = A * 1.76 / 0.052[/tex]
[tex]55000 = A * 33.85[/tex]
[tex]A = 55000 / 33.85[/tex]
[tex]A = 1624.82[/tex]
Therefore the annual payment(A)=1624.82 and since year has 12 months, monthly payment is
[tex]1624.82 / 12 = $135.40[/tex]
Therefore we get the ordinary annuity is $135.40
