The range of score Jim must get to have an average score of 94 or more is x≥ 131

inequality, In mathematics is a statement of an order relationship with greater than, greater than or equal to, less than, or less than or equal to between two numbers or algebraic expressions.

Average is the sum of items divided by the number of items.

Represent the theirs score by x

(78+73+x)/3 ≥ 94

151+x ≥ 94×3

151 + x ≥ 282

x ≥ 282-151

2 cups of 10% sugar solution and 6 cups of 30% sugar solution.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements

Let,

x = number of cups of the 10% solution

y = number of cups of the 30% solution

As this is the whole amount we need, the two mixtures sum up to 8 cups. Consequently, the first equation is just x + y = 8

Solve for y to get y = 8-x. We'll use this equation later.

The second equation is a bit more tricky.

0.10x = amount of pure sugar from just the 10% batch

0.30y = amount of pure sugar from just the 30% batch

0.10x+0.30y = total amount of pure sugar from both batches

25% of 8 = 0.25×8 = 2 = total amount of pure sugar required

0.10x+0.30y = 2 is the second equation

Apply substitution to solve for x and y

0.10x+0.30y = 2 ..... start with the second equation

0.10x+0.30(8-x) = 2 ....... plugin y = 8 - x

0.10x + 2.4 - 0.30x = 2 ..... distribute

- 0.20x + 2.4 = 2 - 0.20x = 2-2.4 ....... subtract 2.4 from both sides

-0.20x = - 0.4

x = -0.4/(-0.20)

x = 2

Now that we know the value of x, we can find y.

y = 8 - x

y = 8 - 2 ... plug in x = 2

y = 6

So we need 2 cups of the 10% solution and 6 cups of the 30% solution.

As a check,

x + y = 2 + 6 = 8 works out

0.10x + 0.30y = 0.102 + 0.306 = 0.2 + 1.8 = 2 works out as well

The artist invests $4500 in the 5% account and $23000 in the 4% account.

Let's call the amount invested in the 5% account x. Then, the amount invested in the 4% account is 4x + 5000.

The total annual interest income from the investments is 1145, so we can write an equation:

0.05x + 0.04(4x + 5000) = 1145

Expanding the second term:

0.05x + 0.04(4x) + 0.04(5000) = 1145

0.05x + 0.16x + 200 = 1145

0.21x + 200 = 1145

0.21x = 945

x = 4500

So the artist invests $4500 in the 5% account and $18000 + 5000 = $23000 in the 4% account.

Step-by-step explanation:

I hope these were helpful.

To determine which of the following subsets of P2 are subspaces of P2, you should use the subspace test from the lectures.

For each subset, you need to check if it is closed under vector addition, closed under scalar multiplication, and contains the zero vector. If the subset satisfies all three conditions, then it is a subspace.

For example, the subset S = {2x2+3x+1, x2+3x+2} is a subspace of P2 because it is closed under vector addition (2x2+3x+1 + x2+3x+2 = 3x2+6x+3) and closed under scalar multiplication (2*(2x2+3x+1) = 4x2+6x+2).

Additionally, it contains the zero vector (0x2+0x+0). Therefore, it is a subspace of P2.

In the isosceles triangle, the value of x for the first figure is 15

for the second figure,

The value of x is solved using the knowledge of isosceles triangle

An isosceles triangle has the base angles equal hence

2x = 35 - 5

2x = 30

x = 15

Second figure

x = 5

let the angle at the peak be p

The sum of p, q, and r is 27.

The point of intersection of the lines t1 and t2, (x,y), can be found by using the equation of the lines. The equation of t1 is y=mx+c, where m is the slope, and c is the y-intercept. The equation of t2 is y=mx+c, where m is the slope, and c is the y-intercept.

The equations of t1 and t2 can be written as y= 1/2 x + 1 and y= -1/4 x + 7/2 respectively.

By setting the two equations equal to each other, we can find the x-coordinate of the point of intersection (x,y).

x=2 - 7/4 =4/4 - 7/4 = -3/4

Since x=p−q√r, we can write -3/4 = p−q√r.

Rearranging this equation, we get p+q+r= 4/3 + 7/3 + 4/3 = 27/3 = 9.

The equation of this circle in standard form is (x + 21)² + (y + 19)² = 849.

The center of the circle is at the point (-21, -19), and its radius is √849 units.

The general form of the equation of a circle that has the same radius as the above circle is x² + y² - 50x - 30y + 1 = 0.

In Mathematics, the standard form of the equation of a circle is represented by this mathematical expression;

(x - h)² + (y - k)² = r²

Where:

In order to transform the general form of the equation of a circle to a standard form, you can either make use of completing the square method or convert the equation x² + y² + Dx + Ey + F = 0 to x² + y² + (-2h)x + (-2k)y + (h² + k² - r²) = 0.

By using the following expression x² + y² + (-2h)x + (-2k)y + (h²+k²-r²) = 0, we would determine the center (h, k) and radius of this circle as follows;

-2h = 42

h = 42/2

h = -21

-2k = 38

k = 38

k = -19

The order of asymptotic magnitude is (3!)3 < 3n < n log(3n) < n3 < 3n < 3n. This means that the function with the smallest asymptotic magnitude is (3!)3, while the function with the largest asymptotic magnitude is 3n.

To confirm this, let's calculate the growth rate of each function.

8cos(4x) can be written as an expression involving only sines and cosines to the first power as 8 - 16sin^2(2x)

The expression 8cos(4x) can be written in terms of sines and cosines to the first power using the double angle identity:

cos(2θ) = 1 - 2sin^2(θ)

First, we can rewrite 4x as 2(2x), and then apply the double angle identity:

cos(4x) = cos(2(2x)) = 1 - 2sin^2(2x)

Next, we can use the identity:

cos(θ) = cos(-θ)

to rewrite cos(2x) as cos(-2x):

cos(4x) = 1 - 2sin^2(2x) = 1 - 2sin^2(-2x)

Finally, we can multiply both sides by 8:

8cos(4x) = 8(1 - 2sin^2(-2x)) = 8 - 16sin^2(-2x)

And since sin(-θ) = -sin(θ), we can write this as:

8cos(4x) = 8 - 16sin^2(2x)

So, 8cos(4x) can be written as an expression involving only sines and cosines to the first power as:

8 - 16sin^2(2x)
