If tanA= x/y find the value of xsinA+ycisB ​

Biology
1 answer:
weeeeeb [17]3 years ago
6 0

Answer:

If tan A = 3 / 5, then sin A = 3√34 / 34 and cos A = 5√34 / 34  .

Assuming x = 5 and y = 3 (The problem is deficient in this regard)

5(3√34 / 34) + 3(5√34 / 34)

30√34 / 34

15√34 / 17

Explanation:

I hope this helps!

Legend has it that there was a less famous geneticist in the 1800s
NNADVOKAT [17]

Answer:

Few crosses

The complexity of cat genetics

Crosses not controlled by the researcher

Explanation:

The purpose of this question is to determine why  Megor Grendel is less famous than that of Gregor Mendel.

Gregor Mendel examined pea plants, which have a number of benefits for deducing genetic rules, including:

  • The researcher has total control over the crosses.
  • Because the peas have both self and cross-fertilization, it is possible to alter the crosses in the simplest way possible.
  • Pea plants may be examined for a greater series of generations than cats or other animals.
  • Because plant genetics is not overly complicated, several traits may be investigated at the same period.

As a result, the primary factors why Megor Grendel's experiments are not well-known:

  • The presence of only a few crossings: It is impossible to establish a genetic theory with such a small number of crossings on the test subject of the organism.
  • Cat genetics is too complicated therefore, the fur gene color on the X-chromosome, a characteristics mosaic inheritance. As a result, It is much too complicated to deduce an inheritance pattern.
  • Crossings that the researcher cannot fully control. Unlike plants, crosses in animals cannot be totally controlled by the researcher.

As a result, it is impossible to draw any conclusions from them.

REY [17]

Answer:

reinstate a previous behavior

Explanation:

The rehabilitation to stop the pain and inflammation, for the recovery of the mobility and the muscular tone and the realization of a program of sports rehabilitation are essential to achieve a good recovery.

The recovery process must be carried out in a precise and multidisciplinary manner, the load that the knee must support and tolerate at all times, as well as rest and recovery times.

If a chemist adds ammonia to a cleaner, he would expect the litmus paper to turn ___________.
bagirrra123 [75]
<span>If a chemist adds ammonia to a cleaner, he would expect the litmus paper to turn blue. Ammonia is a basic compound with no ions, however in solution it gains an ion and becomes ammonium. These basic ions interact with the litmus paper and turn it blue.</span>

Which of the following is most consistent with homeostasis? Select one: a. As blood pressure falls, blood flow to cardiac (heart
alex41 [277]

Answer:

Both C and E are reasonable answers.

Explanation:

Homeostasis describes the body's ability to maintain a stable equilibirum. In other words, if the body experiences a stress, it will generate a response that works to counteract that stress and restore itself to how it was prior to the stress.

A. This describes a cause and effect (BP down --> venous return down). It does not describe an active physiological response to counteract the BP drop such as an increase in heart rate. Not homeostasis.

B. Again, a cause and effect is described. Blood vessel walls becoming thinner is not a response to counteract increased BP. Not homeostasis.

C. Here a response to a stress is described. Men are drinking more water. The body responds by getting rid of that water, restoring the body to its former state. This describes homeostasis.

D. This sounds like homeostasis, but it's actually the opposite of what happens. Dilation of peripheral blood vessels is a way for the body to get rid of heat. This is the opposite of what you would want if the body got colder - it would make the stress worse, which is the opposite of homeostasis. In actuality the response to cold temperature is constriction of blood vessels to preserve heat.

E. This deescribes homeostasis. The stress is increased glucose. The body's response to manage it is to release insulin, which helps remove the glucose from circulation.
