Dmitrij [34]
K(x) = 5x-6
(k+k)(x) = k(x) + k(x) = 5x-6 +5x-6
just plug in x = 4,
(k+k)(4) = 5(4) -6 + 5(4) -6
thats your answer, the last option.

Find the length of the third side. If necessary, write in simplest radical form.
Mazyrski [523]

Answer:

\boxed {\boxed {\sf 8}}

Step-by-step explanation:

This triangle has a small square, which represents a right angle. Therefore, we can use the Pythagorean Theorem.

a^2+b^2=c^2

Where <em>a</em> and <em>b </em> are the legs of the triangle and <em>c</em> is the hypotenuse.

In this triangle, 7 and √15 are the legs, because these sides make up the right angle. The unknown side is the hypotenuse, because it is opposite the right angle. So, we know two values:

a= 7 \\b= \sqrt{15}

Substitute these values into the formula.

(7)^2+(\sqrt{15})^2=c^2

Solve the exponents.

  • (7)²= 7*7=49

49+ (\sqrt{15})^2=c^2

  • (√15)²=√15*√15=15

49+15=c^2

Add.

64=c^2

Since we are solving for c, we must isolate the variable. It is being squared and the inverse of a square is the square root. Take the square root of both sides.

\sqrt{64}=\sqrt{c^2} \\\sqrt{64}= c\\8=c

The third side length is <u>8.</u>

Vikentia [17]

Answer:

<h2>In this particular case,the target population of interest to the university administration constitutes the university students.</h2>

Step-by-step explanation:

  • The university administration is interested to conduct a statistical study to identify the average or mean time taken by the students to find a vacant parking spot.
  • Therefore,the research topic here is the average time taken by the university students to find parking spot. The administrator collects an inconspicuous sample of 240 samples from the target population of the study,which is the overall student population of the university.
  • The sample collected by the university administration is used to observe the average or mean parking time by the university students.

Which answer choice represents an equivalent number sentence of "49 - 12"?
Dahasolnce [82]

Answer:

B

Step-by-step explanation:

A. 37 isn't a number sentence

B. 49 + (-12) = 49-12. They're the same thing  because 49 minus 12 can also be written as 49 plus negative 12

C. 49 + 12 doesn't equal 49-12

D. 12- 49 = -37 which isn't equivalent to 49-12.

Hope this helps!!!
