Answers

Answer 1

Answer:

Answer:

Undefined.

Step-by-step explanation:

When using the formula y2-y1/x2-x1, the result comes out as -4/0. Any number over a 0 is undefined.

Review the incomplete derivation of the cosine sum identity.A 2-column table with 5 rows. Column 1 has entries step 1, step 2, step 3, step 4, step 5. Column 2 has entries cosine (x + y), sine (StartFraction pi Over 2 EndFraction minus (x + y) ), blank, sine (StartFraction pi Over 2 EndFraction minus x) cosine (negative y) + cosine (StartFraction pi Over 2 EndFraction minus x) sine (negative y), blank.

Step 5: cos(x)cos(y) – sin(x)sin(y)
Step 3: Sine ( (StartFraction pi over 2 EndFraction minus x) minus y )

Step 3: Sine ( (StartFraction pi over 2 EndFraction minus x) minus y )
Step 5: cos(x)cos(y) – sin(x)sin(y)

Answers

Answer:

Option (4)

Step-by-step explanation:

STEP - 1

cos(x + y)

STEP - 2

$\text{sin}[(\pi)/(2)-(x+y)]$

STEP - 3

$\text{sin}[((\pi)/(2)-x)-y]$

STEP - 4

$\text{sin}((\pi)/(2)-x)\text{cos}(-y)+\text{cos}((\pi)/(2)-x)\text{sin}(-y)$

STEP - 5

cos(x)cos(y) - sin(x)sin(y)

[Since, $\text{sin}((\pi)/(2)-x)=cos(x)$ and $\text{cos}((\pi)/(2)-x)=\text{sin}(x)$ ]

[Since, cos(-x) = cos(x) and sin(-x) = -sin(x)]

Therefore, Option (4) will be the correct option.

Answer:

Coordinate geometry is one of the most important and exciting ideas of mathematics. In particular it is central to the mathematics students meet at school. It provides a connection between algebra and geometry through graphs of lines and curves. This enables geometric problems to be solved algebraically and provides geometric insights into algebra.

The invention of calculus was an extremely important development in mathematics that enabled mathematicians and physicists to model the real world in ways that was previously impossible. It brought together nearly all of algebra and geometry using the coordinate plane. The invention of calculus depended on the development of coordinate geometry.

What times what gets 6.25 but adds up to5

Answers

2.5 and 2.5 add up to 5, and multiply to get 6.25

Final answer:

The question seeks two numbers which when multiplied result in 6.25 and, when added, give a total of 5. These numbers are 2.5 and 2.5.

Explanation:

The question is seeking for two numbers which when multiplied (times) result in 6.25 and when added (adds up) give a total of 5. These numbers are 2.5 and 2.5. This is because 2.5 times 2.5 equals 6.25, and also 2.5 + 2.5 equals 5.

To illustrate, consider this:

2.5 * 2.5 = 6.25 (multiplication)
2.5 + 2.5 = 5 (addition)

Therefore, the numbers you are looking for are 2.5 and 2.5.

Jayden’s new puppy weighed 11 and one fourth pounds at 4 weeks old. At four weeks, the puppy weighed three fifths times as much as at 16 weeks. Which equation can be used to find how much Jayden’s puppy weighs at 16 weeks old

Answers

Step-by-step explanation:

Weight of the puppy at 4 weeks old:

$\large{11 (1)/(4) }$ pounds = $\large{ (45)/(4) }$ pounds

This weight is 3/5th times of the weight of puppy in 16 weeks. Let's assume the weight of puppy in 16 weeks be x. Then, 3/5th of x is 45/4 pounds.

Inequationform,

$\boxed{ \large{(3)/(5) x = (45)/(4) }}$

Multiplying 5/3 both sides to isolate x on LHS,

$\large{x = (45)/(4) * (5)/(3) }$

$\large{x = (75)/(4) = 18.75}$ pounds

The equation used for finding the weight of puppy is 3x/5 = 45/4. And Jayden's puppy weighed 18.75 pounds in 16 weeks.
