Step-by-step explanation:
The quadratic x^2-4x-14=3x+16 has two solutions. What is the positive difference between these solutions?
To find the positive difference between the solutions of the quadratic equation x^2-4x-14=3x+16, we simplify it to x^2-7x-30=0 and use the quadratic formula. Calculating the solutions, we get 10 and -3, and the positive difference between these solutions is 13.
Explanation:To find the positive difference between the solutions of the quadratic equation x2-4x-14=3x+16, we first need to simplify the equation by subtracting 3x and 16 from both sides to set it equal to zero.
x2 - 7x - 30 = 0
Now, we use the quadratic formula, which is x = ∛(-b ± √(b2 - 4ac))/(2a), to find the solutions for x, where a = 1, b = -7, and c = -30.
∛(-(-7) ± √((-7)2 - 4*1*(-30)))/(2*1)
The solutions are:
x = (7 + √(49 + 120))/2x = (7 - √(49 + 120))/2Calculating the square root and simplifying, we find:
x = (7 + √169)/2x = (7 - √169)/2The solutions then become:
x = (7 + 13)/2 = 20/2 = 10x = (7 - 13)/2 = -6/2 = -3The positive difference between the solutions 10 and -3 is:
10 - (-3) = 13
Therefore, the positive difference between the solutions is 13.
The positive difference between the two solutions is 13.
Start by rearranging the equation [tex]\(x^2 - 4x - 14 = 3x + 16\)[/tex] into standard quadratic form:
[tex]\[ x^2 - 4x - 14 = 3x + 16 \][/tex]
Combine like terms:
[tex]\[ x^2 - 4x - 14 - 3x - 16 = 0 \][/tex]
[tex]\[ x^2 - 7x - 30 = 0 \][/tex]
Now, to find the solutions to this quadratic equation, we can use the quadratic formula:
[tex]\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \][/tex]
For the equation [tex]\(x^2 - 7x - 30 = 0\)[/tex], the coefficients are:
[tex]\[ a = 1, \quad b = -7, \quad c = -30 \][/tex]
Let's substitute these values into the quadratic formula:
[tex]\[ x = \frac{-(-7) \pm \sqrt{(-7)^2 - 4(1)(-30)}}{2(1)} \ \\\\\\[ x = \frac{7 \pm \sqrt{49 + 120}}{2} \ \\\\\\[ x = \frac{7 \pm \sqrt{169}}{2} \ \\\\\\[ x = \frac{7 \pm 13}{2} \][/tex]
So, the solutions are:
[tex]\[ x = \frac{7 + 13}{2} = 10 \ \\\\\\[ x = \frac{7 - 13}{2} = -3 \][/tex]
The positive difference between these solutions is:
[tex]\[ \text{Positive difference} = |10 - (-3)| = |10 + 3| = 13 \][/tex]
Therefore, the positive difference between the two solutions is 13.

A florist is making 5 identical bridesmaid bouquets for a wedding. she has $610 to spend (including tax) and wants 24 flowers for each bouquet. roses cost $6 each, tulips cost $4 each, and lilies cost $3 each. she wants to have twice as many roses as the other 2 flowers combined in each bouquet. how many roses, tulips, and lilies are in each bouquet?
Each bouquet contains 16 roses, 4 tulips, and 4 lilies.
Explanation:To determine the number of roses, tulips, and lilies in each bouquet, we need to set up a system of equations based on the given information. Let's denote the number of roses as 'r', the number of tulips as 't', and the number of lilies as 'l'.
From the problem, we are told that there are twice as many roses as the other two flowers combined in each bouquet. This can be represented by the equation:
r = 2(t + l)
Next, we are given that the florist wants 24 flowers in each bouquet. So the total number of flowers is:
r + t + l = 24
Now we can solve these two equations simultaneously to find the values of 'r', 't', and 'l'.
Substituting the first equation into the second equation, we get:
2(t + l) + t + l = 24
3t + 3l = 24
t + l = 8
Solving this equation, we find t = 4 and l = 4. Plugging these values back into the first equation, we get:
r = 2(4 + 4)
r = 16
So each bouquet contains 16 roses, 4 tulips, and 4 lilies.
If the population density of ocotillo in a desert is 15 per square kilometer, how many plants would be expected in an area that is 5 km by 3 km?
In an area that is 5 km by 3 km, with an ocotillo population density of 15 plants per square kilometer, we would expect to find 225 ocotillo plants.
The student's question pertains to calculating the expected number of ocotillo plants in a given area based on the known population density. First, we need to find the total area of the region in question, which in this case is a desert area that measures 5 km by 3 km. We calculate the area by multiplying the length by the width: 5 km x 3 km = 15 km2.
Since the population density of ocotillo is given as 15 plants per square kilometer, we can find the total number of ocotillos by multiplying the density by the total area:
15 plants/km2 x 15 km2 = 225 plants.
Therefore, in an area that is 5 km by 3 km, we would expect to find 225 ocotillo plants.

Which expression results in a product that is rational?
(a)square root of 7 times square root of 10
(b)square root of 8 times square root of 10
(c) square root of 9 times square root of 10
(d)square root of 10 times square root of 10
Final answer:
The expression that results in a rational product is √10 times √10, as this simplifies to the rational number 10.
Explanation:
To find which expression results in a product that is a rational number, we need to identify which pair of square roots can be multiplied to produce a non-radical number.
Multiplication of square roots is analogous to the multiplication of exponents. When the same base is multiplied, the exponents are added. Utilizing this property, we know:
√7 × √10 = √(7 × 10) = √70 (which is irrational since 70 is not a perfect square).
√8 × √10 = √(8 × 10) = √80 (which is irrational since 80 is not a perfect square).
√9 × √10 = √(9 × 10) = √90 (which is irrational since 90 is not a perfect square).
√10 × √10 = √(10 × 10) = √100 = 10 (which is rational since 100 is a perfect square).
Therefore, the expression that results in a rational product is √10 × √10, which simplifies to 10.

The length of a rectangle is 5 yd less than twice the width, and the area of the rectangle is 52 yd^2. Find the dimensions of the rectangle.
Please help ASAP!
To find the dimensions of the rectangle, we set up an equation using the area formula and solve for 'x'.
Explanation:Let's assume that the width of the rectangle is 'x' yards. Since the length is 5 yards less than twice the width, we can express the length as (2x - 5) yards. The area of a rectangle is given by the formula A = length * width, so we can set up the equation:
A = (2x - 5) * x = 52
Expanding the equation:
2x^2 - 5x - 52 = 0
Using the quadratic formula or factoring, we can solve for 'x'. Once we find the value of 'x', we can substitute it back into the expressions for length and width to find the dimensions of the rectangle.
Dimensions of the rectangle: Width = x yards, Length = (2x - 5) yards

One integer is 2 times another. If the product of the two integers is 32, then find the integers
Final answer:
The two integers that satisfy the conditions of being twice of each other and having a product of 32 are either (4, 8) or (-4, -8).
Explanation:
The two integers as x and y, with y being 2 times x (y = 2x). According to the problem, the product of these two integers is 32 (x * y = 32). If we substitute y in the equation with 2x, we obtain the following: x * 2x = 32. Simplifying this equation gives us a quadratic equation, x² = 16.
To find x, we take the square root of both sides. The square root of 16 is 4, so x can be either 4 or -4. Consequently, y can be either 8 or -8, depending on whether x is positive or negative.
Therefore, the two sets of integers that satisfy the equation x*y = 32 are (4, 8) and (-4, -8), as both pairs have a product of 32 and one integer is exactly twice the other.

To evaluate the line integral, calculate the arclength element and substitute it into the integral. Expand the expression inside the square root, multiply it by (2x+9z), and integrate term by term.
Explanation:To evaluate the line integral of (2x+9z) ds where the curve is given by the parametric equations x=t, y=t^2, z=t^3 for t between 0 and 1, we need to find the arclength element ds and substitute it into the integral. The arclength element ds can be calculated using the formula ds = sqrt(dx^2 + dy^2 + dz^2). In this case, dx = dt, dy = 2t dt, and dz = 3t^2 dt. Substituting these values into the arclength element formula, we get ds = sqrt(dt^2 + 4t^2 dt^2 + 9t^4 dt^2) = sqrt(1 + 4t^2 + 9t^4) dt.
Substituting ds into the line integral, we get the integral of (2x+9z) * sqrt(1 + 4t^2 + 9t^4) dt. To evaluate this integral, you can expand the expression inside the square root, multiply it by (2x+9z), and integrate term by term.
However, it seems that there might be a typo in the original question regarding the curve parametrization. The curve given by x=t, y=t^2, z=t^3 is actually a parabolic curve, not a line. If you need further clarification or assistance, please let me know.
