An equation is shown. 21t = 252

Answer:

dy/dx= 7- 3x^-1/2

when X=1

dy/dx = 4

as it is a tangent M1=M2=4

now,

at gradient 4 and point (1,1)

equation of curve is ,

y-y1= m(x-x1)

or, y-1=4(x-1)

or, y-1=4x-4

or, y-4x= -3

or, 4x-y=3

Answer:

BRAINLEST ANSWER

Step-by-step explanation:

dy/dx=7-3x^-1/2

when x=1

Dy/dx=4

as it is a tangent M1=M2=4 now

at gradient 4 and point(1,1) equation of a curve is y-y1=m(x-x1)

or y-1=4(x-1)

or y-1=4x-4

or y-4x=-3

or 4x-y=3

Answer:

K = 75000 Joules

Step-by-step explanation:

K = 1/2mv^2

K = 1/2(1500)(10^2)

K = 1/2(150000)

K = 75000 Joules

3 x 3

You are multiplying 3 by itself , so you have two 3’s.

Exponential form is the number raised to the total numbers:

Answer is 3^2

Answer:

Simple b is 2

Step-by-step explanation:

1.5(2)= 3

Answer:

2

Step-by-step explanation:

So you need to find how many times to multiply 1.5 to make 3.

Divide 3 by 1.5 and you will get 2.

Answer:

x = 4, y = 5

Step-by-step explanation:

[tex]2x-y=3\\4x-2y=6[/tex]

so:

[tex]4x - 2y = 6\\+ 5x + 2y = 30\\9x= 36\\x=4[/tex]

Substitute this into 2x - y = 3:

[tex]8-y=3\\y = 5[/tex]

Answer:

Y  when X=36 and Z=2 is 90

Step-by-step explanation:

Given -

Y varies directly as X and inversely as the square of Z

[tex]y = \frac{kx}{z^2}\\30 = \frac{k *75}{5^2} \\30 = 75k/25[/tex]

[tex]k = 10[/tex]

As we know

[tex]y = \frac{kx}{z^2}[/tex]

Substituting value of X = 36 and Z = 2 in above equation, we get -

[tex]y = \frac{10*36}{2*2} \\y = 90[/tex]

Answer:

Margret is correct, Kevin is wrong.

Step-by-step explanation:

6^-4 can be written as (1/6)^4

By taking (1/6)^5 times you have (1/6)(1/6)(1/6)(1/6)(1/6), multiplying by 6 would cancel one of those (1/6ths) out. Meaning you would be left with (1/6)^4 or 6^-4

Kevin is wrong because taking 6^4 would not be the same as 6^-4, 6^4= 1296, multiplying that by 1/6 would not give you the same value as 6^-4. His mistake was that he did not take the reciprocal of 6^-4 and incorrectly removed a negative.

The expected number of 5's would be rolled is 5 times if the Gavin rolls a fair dice 30 times.

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

Total outcomes = {1, 2, 3, 4, 5, 6]

Total number of outcomes = 6

Favourable outcomes = {5}

Total number of favourable outcomes = 1

Probability of rolling 5 = 1/6

The expected number of 5's would be 30×(1/6) =  5 times

Thus, the expected number of 5's would be rolled is 5 times if the Gavin rolls a fair dice 30 times.

Answer: I am pretty sure that it is true for some cases

Step-by-step explanation:

Answer:

El perímetro del triángulo rectángulo es aproximadamente 29.627.

Step-by-step explanation:

Las coordendas de los vértices del triángulo rectángulo son [tex]A(x,y) = (1,-2)[/tex], [tex]B(x,y) = (-8,4)[/tex] y [tex]C(x,y) = (5,2)[/tex]. En primer lugar, determinamos las longitudes de los segmentos AB, BC y AC por el Teorema de Pitágoras:

[tex]AB = \sqrt{(-8-1)^{2}+[4-(-2)]^{2}}[/tex]

[tex]AB \approx 10.817[/tex]

[tex]BC = \sqrt{[5-(-8)]^{2}+(2-4)^{2}}[/tex]

[tex]BC \approx 13.153[/tex]

[tex]AC =\sqrt{(5-1)^{2}+[2-(-2)]^{2}}[/tex]

[tex]AC \approx 5.657[/tex]

El perímetro del triángulo ([tex]p[/tex]) es la suma de todos estos segmentos:

[tex]p = AB + BC + AC[/tex]

[tex]p \approx 29.627[/tex]

El perímetro del triángulo rectángulo es aproximadamente 29.627.

Step-by-step explanation:

Answer:

-1

Step-by-step explanation:

here's your solution

=> The value of x = 1

=> The value of y = 2

=> we need to find ( x - y)

=> so, put the value of above variables in it

=> hence, (1 - 2) = - 1

=> - 1 is correct answer
