Sebastian used the information 'The table shows two x-intercepts and it changes from increasing to decreasing' for his deduction. This could suggest that he might be dealing with a quadratics or an inverted expressive function.
Explanation:Based on the choices provided, it appears that Sebastian used the information that 'The table shows two x-intercepts and it changes from increasing to decreasing' in his deduction. An x-intercept in a function table happens where the y-value equals zero. Two x-intercepts imply that there are two points where the function crosses the x-axis. A function's pattern shifting from an increasing pattern to a decreasing pattern is indicative of a maximum point. This suggests that Sebastian may be working with a quadratics or an inverted expressional function.

A certain television is advertised as a 45-inch TV (the diagonal length). If the width of the TV is 36 inches, how many inches tall is the TV?
The TV is 27 inches tall.
Step-by-step explanation:
Given,
The diagonal length of the TV = 45 in
The width of the TV = 36 in
To find the length the the TV.
Formula
By Pythagoras theorem,
h²=l²+b², where h be hypotenuse, b be base and l be height.
Now,
Putting, h=45, b= 36 we get,
45²=l²+36²

While at a bakery, Chad decides to purchase some cupcakes and brownies to share with his friends. He can spend no more than $13, and the bakery charges $3 for a cupcake and $2 for a brownie. Select the inequality in standard form that describes this situation. Use the given numbers and the following variables.
x = the number of cupcakes
y = the number of brownies
Answer:
13 divided by 6
Step-by-step explanation:
Final answer:
The situation where Chad is buying cupcakes and brownies with a budget of $13 is represented by the inequality 3x + 2y ≤ 13, where x is the number of cupcakes and y is the number of brownies.
Explanation:
To express Chad's purchasing situation at the bakery within his budget constraint in inequality form, we need to consider the cost per cupcake and brownie and how many of each he can buy without exceeding his budget of $13. Given that a cupcake costs $3 and a brownie costs $2, the inequality in standard form will reflect the price of each item multiplied by the quantity purchased.
The inequality representing this situation is 3x + 2y ≤ 13, where 'x' is the number of cupcakes and 'y' is the number of brownies. This inequality means that the total cost of cupcakes and brownies combined must not exceed $13, which corresponds to Chad's budget constraint.
Find all real square roots of -121.
The real square roots of -121 are ±11i, where 'i' represents the imaginary unit.
Explanation:When dealing with square roots of negative numbers, it's important to recognize that the square root of a negative number is an imaginary number. In this case, the square root of -121 is found by taking the square root of the positive value of 121 and then multiplying the result by 'i'. The square root of 121 is 11, so the square root of -121 becomes ±11i.
In the context of real numbers, square roots of negative values do not exist. However, in the realm of complex numbers, the introduction of the imaginary unit 'i' allows for the representation of square roots of negative numbers. The number 'i' is defined as the square root of -1. When squared, 'i' multiplied by itself yields -1.
Hence, the square root of -121, which is a negative number, results in ±11i, representing two imaginary numbers with opposite signs. These imaginary square roots are crucial in various fields, including mathematics, physics, and engineering, where complex numbers play a significant role in modeling and solving problems involving quantities with both real and imaginary components.

Write the sentence as an equation. The product of r and 338 plus 97 is the same as r.
Answer:
Step-by-step explanation:
To write this sentence as equation
We get
r×338+97=r
338r+97=r
To solve further
r-338r=97
-337r=97
r=-0.2878
The given sentence can be written as the equation: 338r + 97 = r. By following the steps to identify the product, add 97, and set the expression equal to r, we achieve the correct equation. This equation can now be solved for r.
To translate the sentence into an equation, follow these steps:
Identify the key components: product of r and 338 can be written as 338r.Add 97 to this product, which gives 338r + 97.This expression is the same as r, yielding 338r + 97 = r.Therefore, the equation representing the given sentence is 338r + 97 = r.
Terry is going to make some concrete mix. He needs to mix
cement, sand and gravel in the ratio 2 . 3 : 5 by weight. He
estimates he needs to make 220 kg of concrete mix.
Terry has:
• 50 kg of cement
• 90 kg of sand
• 100 kg of gravel
Does Terry have enough cement, sand and gravel to make the
concrete mix?
Answer:
No
Step-by-step explanation:
Sum the parts of the ratio, 2 + 3 + 5 = 10 parts
Divide 220 Kg by 10 to find the value of one part of the ratio.
220 Kg ÷ 10 = 22 Kg ← value of 1 part of the ratio, thus
2 parts = 2 × 22 = 44 Kg ← quantity of cement needed
3 parts = 3 × 22 = 66 Kg ← quantity of sand needed
5 parts = 5 × 22 = 110 Kg ← quantity of gravel needed
He has the required amounts of cement and sand but not of gravel.
Thus he cannot mix the concrete
Terry requires 44 kg of cement, 66 kg of sand, and 110 kg of gravel for the concrete mix. He has enough cement and sand but is short of gravel by 10 kg, so he cannot make the complete mix with the materials he currently has.
Explanation:First, we calculate the total parts of the mix by adding the ratio numbers: 2 (cement) + 3 (sand) + 5 (gravel) = 10 parts in total. Next, we find out how much each part weighs: 220 kg ÷ 10 parts = 22 kg per part. Then we multiply the number of parts for each material by the weight per part: Cement needed = 2 parts × 22 kg/part = 44 kg, Sand needed = 3 parts × 22 kg/part = 66 kg, Gravel needed = 5 parts × 22 kg/part = 110 kg. Now, let's compare these requirements with what Terry has:
Cement: needs 44 kg, has 50 kg — enoughSand: needs 66 kg, has 90 kg — enoughGravel: needs 110 kg, has 100 kg — not enoughIn conclusion, Terry does have enough cement and sand, but he does not have enough gravel for the mix.
