Ans it fast plz.​
i will mark u as brainliest.

Answers

Answer 1

Answer:

4a^2 + 9a + 10

Step-by-step explanation:

First we distribute

-4a^2 + (−6a) + (5)(3a) + (5)(2)

-4a^2 - 6a + 15a + 10

Then we combine like terms

4a^2 has no like terms, so it cannot be added onto anything else.

We add -6a to 15a

15a - 6a = 9a

4a^2 + 9a + 10

Answer 2

Answer:

Simplifying

(6a + -8)(4a2) = 0

Reorder the terms:

(-8 + 6a)(4a2) = 0

Remove parenthesis around (4a2)

(-8 + 6a) * 4a2 = 0

Reorder the terms for easier multiplication:

4a2(-8 + 6a) = 0

(-8 * 4a2 + 6a * 4a2) = 0

(-32a2 + 24a3) = 0

Solving

-32a2 + 24a3 = 0

Solving for variable 'a'.

Factor out the Greatest Common Factor (GCF), '8a2'.

8a2(-4 + 3a) = 0

Ignore the factor 8.

Subproblem 1

Set the factor 'a2' equal to zero and attempt to solve:

Simplifying

a2 = 0

Solving

a2 = 0

Move all terms containing a to the left, all other terms to the right.

Simplifying

a2 = 0

Take the square root of each side:

a = {0}

Subproblem 2

Set the factor '(-4 + 3a)' equal to zero and attempt to solve:

Simplifying

-4 + 3a = 0

Solving

-4 + 3a = 0

Move all terms containing a to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + 3a = 0 + 4

Combine like terms: -4 + 4 = 0

0 + 3a = 0 + 4

3a = 0 + 4

Combine like terms: 0 + 4 = 4

3a = 4

Divide each side by '3'.

a = 1.333333333

Simplifying

a = 1.333333333

Solution

a = {0, 1.333333333}

You can model an arch at your school using the equation $y=-0.5\left(x+4\right)\left(x-4\right)$ , where $x$ and $y$ are measured in feet. The x-axis represents the ground. Find the width of the arch at ground level.

Answers

Answer:

8feet

Step-by-step explanation:

Given the equation that models the arch of a school expressed as;

[tex]$y=-0.5\left(x+4\right)\left(x-4\right)$[/tex]

If the x axis represents the ground;

At the ground level, x = 0

Substitute x = 0 into the equation to get y;

y = -0.5(0+4)(0-4)

y = -0.5(4)(-4)

y = -0.5 * -16

y = 8ft

Hence the y axis at the ground level is 8feet

so C (y is -5 for both)

if my answer helps please mark as brainliest.

Answer:

C

Step-by-step explanation:

A line with slope of zero means that the y value doesn't change like the x axis. so we'll need to find points that even though they have different x values, they have the same y value. That. being said C is the answer

A rectangle is 60 cm long and 20 cm wide. Find, to the nearest tenth of a degree, the acute angle formed at the intersection of the diagonals.

Answers

Answer:

36.9°

Step-by-step explanation:

As shown in the diagram attached,

θ is the acute angle formed at the intersection of the diagonals of the rectangle.

From the diagram,

tan(θ/2) = 10/30

tan(θ/2) = 1/3

θ/2 = tan⁻¹(1/3)

θ/2 = 18.43

Therefore,

θ = 18.43×2

θ = 36.87

θ = 36.9°

Hence the acute angle formed is 36.9°

The Invasion of the Lionfish


What was once just an attractive aquarium fish has recently become one of the biggest menaces in the Atlantic. The lionfish was accidentally introduced into the Atlantic Ocean in the 1990s. Because it has no natural predators, it has adapted quickly to its new home. The lionfish now threatens to destroy native fish populations in the Atlantic, Caribbean, and Gulf of Mexico.


The lionfish spreads quite rapidly. Lionfish spread faster than any other invading species. Experts have called the invasion in the Atlantic the worst marine invasion of all time. The lionfish's success comes from an ability to reproduce all year round. In addition, they are greedy eaters with a fondness for small fish and crustaceans. They will eat anything smaller than they are. Lionfish love the warm waters of the Gulf of Mexico. Since their first sighting, they have rapidly multiplied. In some locations, scientists estimate that lionfish populations exploded by 700 percent between 2004 and 2008 alone.


To combat the invasion, wildlife agencies have sponsored lionfish derbies. In these derbies, local scuba divers are invited to harvest lionfish. In addition, many states offer recipes for preparing and eating lionfish to encourage harvesting. Lionfish have to be handled carefully because of their venomous spines, but they are apparently delicious. Increasing the harvest of lionfish will help. However, scientists estimate that more than a quarter of the population would have to be taken every month to stop the growing population.


The lionfish has targeted our most fragile and important ecosystems. Scientists are working tirelessly to learn as much as they can about this predator. We may never be able to completely remove the threat, but many fishermen and seafood fans are hoping we can figure out how to control it.

Given the slope of the line containing the points (7 , b) and (-2 , 5) is 4/9, find the value of b​

Answers

Answer: b=9

Step-by-step explanation: To find the slope we use: y2-y1/x2-x1

Which would then be: 5-b/-2-7= 5-b/-9

Then we have to find a number for b that would give us -4 as the numerator. That number would be 9

This would give us 4/9 which is the slope we already had.
