Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identity

tan²x + 1 = sec²x

Consider the left side

[tex]\frac{1+sin^4A}{cos^4A}[/tex]

= [tex]\frac{1}{cos^4A}[/tex] + [tex]\frac{sin^4A}{cos^4A}[/tex]

= [tex]sec^{4}[/tex] A + [tex]tan^{4}[/tex] A

= (tan²A + 1)² + [tex]tan^{4}[/tex] A

= [tex]tan^{4}[/tex] A + 2tan²A + 1 + [tex]tan^{4}[/tex] A

= 1 + 2tan²A + 2[tex]tan^{4}[/tex] A ← factor out 2tan²A

= 1 + 2tan²A(1 + tan²A)

= 1 + 2tan²A sec²A

= right side , thus verified

Answer:

Saturday

Step-by-step explanation:

First we have to find the LCM of 3 and 4

It is 12, so we know that she will jog and swim every 12 days

This time was Monday, so 12 days after Monday will be the day she both jog and swims.

12 days after Monday is Saturday, so the next time she jogs and swims is Saturday.

Answer:

A: [tex]y=3x+12[/tex]

Step-by-step explanation:

To start we need to know what makes lines perpendicular. Two perpendicular lines will have opposite-reciprocal slopes, because we know that they intersect at a right angle.

Then, we need to understand the slope-intercept form of an equation. The slope intercept form is [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope of the line and [tex]b[/tex] is the y-intercept. We also know that [tex]x[/tex] and [tex]y[/tex] represent points on the line.

Now, since our equation is already in the correct form, we can start with finding the opposite reciprocal of the slope. To do this, all we have to do is flip the fraction upside down and multiply by -1. This means that the opposite reciprocal of [tex]-\frac{1}{3}[/tex]  would be [tex]\frac{3}{1}[/tex] which can be written as [tex]3[/tex].

Now, since we have a list of options and only one has the correct slope, we can safely choose option A.

Answer:

The congruent segments are LN and NK ⇒ C

Step-by-step explanation:

If a line is a perpendicular bisector of another line, that means this line intersects the other line in its midpoint and form right angles around this point

∵ Line JM is the perpendicular bisector of line LK

→ That means JM intersect LK at the midpoint of LK

∵ Line JM intersects line LK at point N

∴ Point N is the midpoint of LK

∵ N divides LK into two segments LN and NK

∵ N is the midpoint of LK

→ That means LN equals NK

∴ LN = NK

∴ The congruent segments are LN and NK

15:51 for Crunch bars

14:51 for Hershey's

10:51 for Mr. Goodbars

12:51 for Cookies and Cream

There are 51 candies in total. We got that by adding all of the candies together. 15 + 14 + 10 + 12 = 51. The probability can be written as a ratio between the different types of candy and the whole number.

The probability of crunch bars, Hershey’s chocolate bars, Mr.Goodbars, and Hershey’s cookies and cream bars are 15/51, 14/51, 10/51, and 12/51, respectively.

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

The probability can be written as,

P(Crunch bars) = Number of Crunch bars/ Total number of choclates= 15/51

P(Hershey's Chocolate) = 14/51

P(Mr. Goodbars) = 10/51

P(Hershey’s cookies and cream bars) = 12/51

Hence, the probability of crunch bars, Hershey’s chocolate bars, Mr.Goodbars, and Hershey’s cookies and cream bars are 15/51, 14/51, 10/51, and 12/51, respectively.

You just divide 1000 by 40

Answer:

This is a tough one, I see why you are confused. The answer would be 50

Step-by-step explanation:

I used process of elimination and working backwards

First I took the first option (50) and added 10. Then divided it by 5 to isolate the X value. I plugged the X value into the (11x+3) and got 135. The missing angle is 45. 50+45+85=180

Step-by-step explanation:

Since the angle 2 is alternate angle to angle 6,they are both equal. So, the angle 6 is 70.

Answer:

56 pencils and pens

Step-by-step explanation:

3:5 is the ratio, and then put that into a fraction and then make a proportion

3/5=21/x

eCross multiply and divide so do 21*5 divided by 3. This gives us an answer of 35. Now we know we have 35 pens. 35+21, adding the pen and pencil, is 56. You can always also look for relationships, so if you could see that multiplying 7 gives you the answer, than do that to the 5, and then add it together.

Answer:

The powers of 10 are things of the form:

10^n.

Where we assume that n is an integer number.

if is equal or larger than 0, then:

We add n zeros at the right of the 1.

so let's write some examples.

10^0 = 1  (we do not add any zero)

10^1 = 10 (we add one zero)

10^2 = 100  (we add two zeros)

...

Now, remember that x^-y = 1/x^y, then:

If n is smaller than zero, then we add n zeros at the left of the 1.

10^-1 = 1/10 = 0.1   (one zero at the left)

10^-2 = 1/100 = 0.01    (two zeros at the left).

Those relations will be useful to always know the exact dimensions of the powers of zero.

Now, we can give a more complete description knowing that:

x^a*x^b = x^(a + b)

Then if we have:

10^3*10^4 = 100*1,000 (and this may be hard to do)

But we can use the above relation:

10^3*10^4 = 10^(3 + 4) = 10^7

Then we know that we must add 7 zeros at the right of the 1.

And this will work for any integer powers of 10.

Answer:

Step-by-step explanation:

The area of rectangle is 3[tex]c^{6}[/tex]-12[tex]c^{5}[/tex] + 9[tex]c^{4}[/tex].

The area of any rectangle is calculated, once its length and width are known. By multiplying length and breadth, the rectangle's area will obtain in a square-unit dimension.

Area of a Rectangle. A = l × b.

Given:

height = 3[tex]c^{4}[/tex]

width = c² - 4c +3

So, Area of rectangle

=length *  width

= 3[tex]c^{4}[/tex] * (c² - 4c +3)

=3[tex]c^{6}[/tex]-12[tex]c^{5}[/tex] + 9[tex]c^{4}[/tex]

Hence, the area of rectangle is 3[tex]c^{6}[/tex]-12[tex]c^{5}[/tex] + 9[tex]c^{4}[/tex].

Answer:

Step-by-step explanation:

In this problem, we first need to find the rate at which syn burns calories per minute

so in 15mins, he burns 200 calories

    in 1 mins he will burn x

x= 200/15

x=13.33 calories per min this is the rate

So in one minute he will burn 13.33 calories

Now using the idea of rate=quantity/time

the rate=13.33

quantity=15 calories

time=?

time=quantity/rate

time=150/13.33

time=11.25min

   Alternatively

(very fast approach)

         if syn spend 15min to burn 200 cal

then he will spend x min to burn 150 cal

cross multiply

x=(150*15)/200

x=2250/200

x=11.25mins
