Answer:

No

Step-by-step explanation:

To find out if 2 is a solution, replace all the x's with 2.

4(2 - 1) - 3(2 - 2) =8

4(1) - 3(0) = 8

4 - 0 = 8

4 = 8

Nope!  False!  2 is not a solution.

Answer:

Number 1 is S

Number 2 is 0.4

Number 3 is 8 yards per second

Number 4 is 4 hours.

Answer:

4

Step-by-step explanation:

4^4 or 4 * 4 * 4 * 4 is 256.

Answer:

[tex] \sqrt[4]{256} [/tex]

[tex] \sqrt[4]{ {4}^{4} } [/tex]

=±4 is a required answer

Answer:

A) x = 7

Step-by-step explanation:

7x + 1 + 7x + 6 + (180 - 15x) = 180

combine like terms:

-x + 187 = 180

subtract 187 form both side of the equation:

-x = -7

x = 7

Answer:

B

Step-by-step explanation:

use y=mx+c

follow the flow

Answer:

250 lifeguards

(P.S, i dunno if i got it right or not should be correct tho)

Step-by-step explanation:

15 km divide 0.06 for every life guard. therefore, there are 250 lifeguards

There will be 9 lifeguards

.6 x 15 = 9

0.06 x 15 = 0.9

0.9 as a whole number = 9

Therefore There will be 9 lifeguards

Answer:

Exponential

Step-by-step explanation:

The rate of change is exponential.

Answer:

The responses to the given question can be defined as follows:

Step-by-step explanation:

Its color palette depends on how much radiation reaches the eyes or the intensity of it. If indeed the duration of a wave is less than 400 nm, it is called UV and much more than 750 nm simple pleasures light it is (IV). The shorter wavelength implies a much more frequent spectrum and lower frequencies are the longer wavelengths.  

The shorter the distance, the higher it's indeed. Since the red duration has been longer, the intensity is low. The purple has a smaller range and a high frequency, on the other side. The wavelengths are shorter as well as the frequencies are lower than the red, and it will differ even as violet goes, Remember that even more power is provided with the longer the duration of color. That wave/frequency color rises and is longer the purple color is becoming the lowest color.

Answer:

19.7°

Step-by-step explanation:

In ΔTUV, the measure of ∠V=90°, UV = 3.3 feet, and TU = 9.8 feet. Find the measure of ∠U to the nearest degree.

We make use of sine rule

TU/sin V = UV/sin U

9.8/sin 90 = 3.3/sin U

Cross Multiply

sin 90 × 3.3 = 9.8 × sin U

sin U = sin 90 × 3.3 /9.8

U = arc sin ( sin 90 × 3.3/9.8)

U = 19.7°

Answer:369.15

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

The maximum value is the y- coordinate of the vertex

Given a quadratic in standard form , y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

y = - x² + 6x + 5 ← is in standard form

with a = - 1 and b = 6 , then x- coordinate of vertex is

x = - [tex]\frac{6}{-2}[/tex] = 3

Substitute x = 3 into the function for y- coordinate of vertex

y = - 3² + 6(3) + 5 = - 9 + 18 + 5 = 14

maximum value is 14 → D

Answer:

24.4

Step-by-step explanation:

14² + 20² = c²

196 + 400 =  596

√596 = 24.4

Answer:

Complementary, x=10

Step-by-step explanation:

Complementary angles mean they add up to 90 degrees.

So 29+(6x+1)=90.

30+6x=90

6x=60

x=10

Answer:

Complementary-------- x= 10

Step-by-step explanation:

only 90 degrees

-----------------------------

3. 6x = 60

=======================

x= 10

Answer:

(426 ; 468)

Step-by-step explanation:

Confidence interval :

Mean score ± margin of error

Margin of Error = 21

Mean SAT score = 447

Hence,

447 ± 21

Lower boundary = 447 - 21 = 426

Upper boundary = 447 + 21 = 468

(426 ; 468)

Answer:

h=8ft

p=a

b=7ft

now,

h^2=p^2+b^2

8^2=a^2+7^2

64=a^2+49

64-49=a^2

√15=a

Step-by-step explanation:

7×2=14(+)

Answer:

Jesse can pack 18 books.

Step-by-step explanation:

2.4*18=43.2+5.7==48.9

you cant fit more than fifty becaue 48.9+2.4=51.3, thus 18 is your answer
