Answer:

The answer is 140 cars .

Step-by-step explanation:

$\frac{1}{5}$ × 300 = 60

$\frac{1}{3}$ × 300 = 100

100 + 60 = 160

300 - 160 = 140

TEXT:

One-fifth of 300 is 60. One-third of 300 is 100. If you add both vintage and race cars you get 160. the total, 300, minus the vintage and race cars, 160, is 140 cars.

Solve the following inequality in two ways and make a claim as to which

NikAS [45]

Answer:

The solution of the given inequality n < 5

Step-by-step explanation:

Explanation:-

Given inequality

$\frac{1}{4} (8 n -12 ) < n +2$

Step(i):-

Cross multiplication '4' we get

8 n - 12 < 4 ( n +2)

8 n - 12 < 4 n + 4×2

8 n - 12 < 4 n +8

Subtracting '4 n ' on both sides, we get

8 n - 4 n - 12 < 4 n - 4 n +8

4 n - 12 < 8

Step(ii):-

Adding ' 12 ' on both sides , we get

4 n -12 + 12 < 8 + 12

4 n < 20

Dividing "4' on both sides , we get

n < 5

The solution is n < 5

Conclusion:-

The solution of the given inequality n < 5

Suppose T: ℝ3→ℝ2 is a linear transformation. Let U and V be the vectors given below, and suppose that T(U) and T(V) are as given

ira [324]

Answer:

$T(3u+2v)=(-10,29)$

Step-by-step explanation:

T is a linear transformation, hence it is homogeneous (T(cr)=cT(r) for all real c and r∈ℝ³) and additive (T(r+s)=T(r)+T(s), for all r,s∈ℝ³). Apply these properties with r=3u and s=2v to obtain:

$T(3u+2v)=T(3u)+T(2v)=3T(u)+2T(v)=3(-2,5)+2(-2,7)=(-6,15)+(-4,14)=(-10,29)$

We don't have an explicit definition of T, so it's more difficult to compute T(3u+2v) directly without using these properties.

1.) Solve 2x^2-12x+20=0 using the quadratic solution set? What is the solution set?

marshall27 [118]

Please, share just ONE problem at a time. Thanks.

Solve 2x^2-12x+20=0:
Simplify this by dividing each term by 2: x^2 - 6x + 10 = 0

Identify a, b and c: a=1, b=-6 and c=10. Then b^2=36.

Write out the solutions using the quadratic formula:

6 plus or minus sqrt(36-40)
x = ---------------------------------------
2

sqrt(36-40) = sqrt(-4) = plus or minus i2

Then:

6 plus or minus i2
x = --------------------------- (answer)
2

Identify the domain and range

UkoKoshka [18]

Answer:

Domain: 1 ≤ x ≤ 4

Range : 1 ≤ f(x) ≤ 4

Step-by-step explanation:

The domain of a function f(x) is the limit within which the values of x varies.

Here, in the graph, it shows that the maximum value of x is 4 and the minimum value of x is 1.

Therefore, the domain of the function is 1 ≤ x ≤ 4

Again the range of a function f(x) is the limit within which the values of f(x) vary.

Here, the graph shows that the maximum value of f(x) is 4 and the minimum value of f(x) is 1.

Therefore, the range of the function f(x) is 1 ≤ f(x) ≤ 4. (Answer)
