sorry for all the screen wrinkles but what’s this

Answer:

s=ut +atsq/2

120=4u+4sq

4u=104

u=26m/sec

Answer:

26 m/s

Step-by-step explanation:

Given

[tex]s = ut + \frac{1}{2} {at}^{2} [/tex]

When a = 2 , s = 120 and t = 4

Then

[tex]120 = u \times 4 + \frac{1}{2} \times 2 \times {4}^{2} \\ 120 = 4u + 16 \\ 120 - 16 = 4u \\ 104 = 4u \\ u = \frac{104}{4} \\ u \: = 26

Hope it will help :)❤

Answer:

x=-18

Step-by-step explanation:

Answer:

x = -18

Step-by-step explanation:

5 - x = 23

5 - 5 - x = 23 - 5

-x = 18

-1x / -1 = 18 / -1

x = -18

Hope this helps and stay safe, healthy, and happy, thank you :) !!

Answer:

A. Voters age 40 and over are least likely to favor road expansion.

Answer:

Value = 44,0000(0.75)^t

Where t = number of years

Value after 4 years = 44,000 (0.75)^4

Answer: a reflection across the x-axis

Answer:

The population in 2015 will be 165 million.

Step-by-step explanation:

The exponential growth formula is given by:

[tex] f(t) = a(1 + r)^{\Delta t} [/tex]

Where:

a: is the initial population

r: is the rate of increase

Δt: is the time        

With the initial information we can find the rate:

[tex] 151 = 145(1 + r)^{1998-1990} [/tex]      

Using logarithm:                                    

[tex] ln(151) = ln(145) + 8[ln(1 + r)] [/tex]  

[tex] ln(1 + r) = \frac{ln(151) - ln(145)}{8} [/tex]                        

[tex] ln(1 + r) = 5.0683 \cdot 10^{-3} [/tex]          

Using exponential:          

[tex] e^{ln(1 + r)} = e^{5.0683 \cdot 10^{-3}} [/tex]

[tex] r = 5.081 \cdot 10^{-3} [/tex]        

Now, we can find the estimated population in 2015:

[tex] f(t) = 151(1 + 5.081 \cdot 10^{-3})^{2015-1998} [/tex]              

[tex] f(t) = 165 [/tex]              

Therefore, the population in 2015 will be 165 million.

I hope it helps you!

Step-by-step explanation:

let x and y be the number of chip and pretzel bags respectively  : 4x%2B2y%3 C=20 : if x=1 then 4%281%29%2B2y%3C=20--->{{2y<=16}}}--->y%3C=8  : if x=3 then 4%283%29%2B2y%3C=20--->{{2y<=8}}}--->y%3C=4  : so chips 1 and pretzels 8  : chips 3 and pretzels 4.

Answer:

b

Step-by-step explanation:

Answer:

137

Step-by-step explanation:

A linear pair adds up to 180 so if you subtract 180 minus 43 its 137 (a)

Then since a parallel line cut by a transversal forms alternate interior angles, (b) would equal 137 also

The since vertical angles are congruent, (b) is equal to ? which is 137

Answer:

L=18cm

W=10cm

Step-by-step explanation:

Given data

let the length be x

L=x

Width= x-8

W= x-8

Perimeter= 56cm

But we know that the perimeter is expressed as

P=2L+2W

substitute our data

56=2(x)+2(x-8)

56=2x+2x-16

56+16=4x

72=4x

divide both sides by 4

x= 72/4

x=18cm

Hence the Length is 18cm

L=18cm

The width= 18-8

W=10cm

Answer:

f^-1(x)= -x/5 - 4/5

Step-by-step explanation:

Answer:

a:95

b: a=75

Step-by-step explanation:

For a:

The angles are supplementary meaning they add to 180º. So you can set up an equation: x + 85 = 180

Subtract 85 from both sides:

x = 95º

For b:

Since it's an isosceles triangle (2 congruent sides), the base angles are equal to each other. So a = 75º

Answer:

1,500

Step-by-step explanation:

Answer:

[tex]\frac{(x + 1)(x - 2)}{x^{2} + 5}[/tex] This is the third option.

Step-by-step explanation:

Dividing a fraction is the same as multiplying the reciprocal of the second fraction.

[tex]\frac{x + 1}{x + 4}[/tex] × [tex]\frac{(x + 4)(x - 2)}{x^{2} + 5}[/tex]

[tex]\frac{(x + 1)(x + 4)(x - 2)}{(x + 4)(x^{2} + 5)}[/tex]  Here, we can just get rid of the (x + 4) because it is common in both the numerator and denominator so they cancel each other out.

So the answer would be [tex]\frac{(x + 1)(x - 2)}{(x^{2} + 5)}[/tex] .

I hope this makes sense!! ^-^
