160/40 = 4
Answer:
Step-by-step explanation:
40
h
Explanation:
We're asked to find the time it takes an object (bird) to travel
1800
km
at a constant speed of
45
km/h
.
We have our simplified speed equation:
speed
=
distance
time
Rearranging for time:
time
=
distance
speed
We're given:
speed
=
45
km/h
distance
=
1800
km
Plugging these in:
time
=
1800

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the zeros 4 and 3−i.
Answer:
[tex]P(x) = x^3 - 10x^2+ 34x-40[/tex]
Step-by-step explanation:
Given
[tex]p =1[/tex] -- Leading coefficient
[tex]Zeros: 4\ and\ 3 - i[/tex]
Required
Determine the polynomial
Represent the zeros with a and b
Such that
[tex]a = 4[/tex]
[tex]b = 3 - i[/tex]
The polynomial is:
[tex]P(x) = p * (x - a) * (x - b)[/tex]
[tex]P(x) = 1 * (x - 4) * (x - (3 - i))[/tex]
However, to solve further: We need to symmetrise over 3-i and its conjugate
[tex]P(x) = 1 * (x - 4) * (x - (3 - i))* (x - (3 + i))[/tex]
[tex]P(x) = (x - 4) * (x - (3 - i))* (x - (3 + i))\\\\[/tex]
To define a suitable function, the expression becomes
[tex]P(x) = (x - 4) * ((x - 3)^2+1)[/tex]
[tex]P(x) = (x - 4) * ((x - 3)(x - 3)+1)[/tex]
[tex]P(x) = (x - 4) * (x^2 - 6x + 9+1)[/tex]
[tex]P(x) = (x - 4) * (x^2 - 6x +10)[/tex]
Open bracket
[tex]P(x) = x^3 - 6x^2 +10x - 4x^2 + 24x-40[/tex]
[tex]P(x) = x^3 - 6x^2 - 4x^2+10x + 24x-40[/tex]
[tex]P(x) = x^3 - 10x^2+ 34x-40[/tex]

Answer:
Hope this helps! If I could have brainliest I'm trying to rank up :)
Step-by-step explanation:
1.x = 37.08 feet
Using the Pythagorean Theorem:
x^2 + 15^2 = 40^2
x^2 + 225 = 1600
x^2 = 1600 - 225
x^2 = 1375
x = SQRT(1375)
x = 5SQRT(55)
x = 37.08 feet
2.Using pathagorean it’s 16^2 + 24^2 = c^2
256 + 576 = 832
The answer is the sqrrt of 832
Which is 8sqrrt13 or 28.44

Answer:
polygon B = 20 meters
Step-by-step explanation:
polygon A : polygon B
3 : 4
15 : x
first take 15 and divide by 3, this would tell us how much it went up by:
15 ÷ 3 = 5
next, take 4 and multiply it by 5:
4 x 5 = 20
this means that polygon B is 20 meters

There are 480 calories are in the 3-ounce size of the bar.
What is mean by Multiplication?Multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
We have to given that;
Green Frog convenience store supplies two types of protein bars.
And, One protein bar has 320 calories in the 2-ounce size.
Now,
For 1 ounce size, calories in One protein bar = 320 / 2
= 160
Hence, We get;
For 3 ounce size, calories in One protein bar = 160 x 3
= 480
Thus, There are 480 calories are in the 3-ounce size of the bar.

The wages w (in £) June earns is the number of hours she works n multiplied by her hourly rate r (in £ per hour). Enter a formula for June's wages and enter the wage she would earn if she worked 17 hours at a rate of £7.30 per hour
Answer:
Wages she earn = £124.1
Step-by-step explanation:
Given:
Number of hour work in June = 17 hour
Rate = £7.30 per hour
Find:
Wages she earn
Computation:
Wages she earn = Number of hour work in June x Rate
Wages she earn = 17 x £7.30
Wages she earn = £124.1
