ololo11 [35]3 years ago
8 0

Answer:

The equivalent expression is 7(1+i)

Step-by-step explanation:

Additional of complex numbers:

When we add complex numbers, we add both it's real parts and imaginary parts.

In this question:

(3 + 2i) + (4 + 5i) = 3 + 4 + (2+5)i = 7 + 7i = 7(1+i)

The equivalent expression is 7(1+i)

Solve the quadratic equation below<br><br> x2-64=0
Montano1993 [528]

Answer:

x=32

Step-by-step explanation:

first, you add 64 to both sides and you have:    x2=64

second, you divide 2 on both sides to get x by itself, so 64 divided by 2 is 32

Pls help :) determine which function has a greater rate and explain how you know.
Nesterboy [21]

Using exponential function concepts, it is found that the second function has a greater rate, as 0.8 > 0.2.

<h3>What is an exponential function?</h3>

It is modeled by:

y = ab^x

In which:

  • a is the initial value, that is, y when x = 0.
  • b is the rate of change, as a decimal.

Function 1 is given by:

y = 2(0.2)^x

Hence the rate is b = 0.2.

Considering the values on the table, function 2 is given by:

y = (0.8)^x

Hence the rate is b = 0.8.

Hence, the second function has a greater rate, as 0.8 > 0.2.

15. Using the circle below, find each arc length. Round to the nearest hundredth. R a) ST b) RPT 97 125 PS = 28 feet
Troyanec [42]

The measure of arcPR and arcRPT are 83 and 208 degrees respectively

The measure of arc ST will be gotten using the expression below:

arcPS = arcPT + arcST

Given the following

  • arcPT = 125 degrees
  • arc PS = 180 degrees

arcST = arcPS - arcPT

arcST = 180  - 125

arcST = 55 degrees

Similarly, arcPR = 180 - arcRS

arcPR = 180 - 97

arcPR = 83 degrees

arcRPT = arcPR + arcPT

arcRPT = 83 + 125

arcRPT = 208 degrees

Hence the measure of arcPR and arcRPT are 83 and 208 degrees respectively

An isosceles triangle △ABC with the base BC is inscribed in a circle. Find the measures of angles of the triangle, if measure of
____ [38]

Answer:

  • angle at A: 51°
  • base angles: 64.5°

Step-by-step explanation:

The measure of the inscribed angle BAC is half the measure of the intercepted arc BC, so is 102°/2 = 51°.

The base angles  at B and C are the complement of half this value, or ...

  90° -(51°/2) = 64.5°

The angle measures in the triangle are ...

  ∠A = 51°

  ∠B = ∠C = 64.5°
