Write a polynomial of least degree with roots 2 and – 7
Answer: x^2+5x-14
Step-by-step explanation:
2 and -7 are the roots of the polynomial then we have to write them as
x=2 ,x=-7
To convert these as factors, we have to write them as
( x-2) (x+7)
The product of those factors will give the polynomial. Because we have two factors, we will get a quadratic polynomial.
x^2+7x-2x-14
x^2+5x-14
Number of factors = Highest exponent of the polynomial
Answer:
y = x² + 5x - 14
Step-by-step explanation:
Given roots x = a, x = b, then the corresponding factors are
(x - a) and (x - b) and the polynomial is the product of the factors
y = (x - a)(x - b)
Here the roots are x = 2 and x = - 7, then the factors are
(x - 2) and (x - (- 7)) = (x + 7), so
y = (x - 2)(x + 7) ← expand using FOIL
y = x² + 5x - 14

please answer this question if you are correct i will mark brainliest
Step-by-step explanation:
Since there are 4 people who answered that they had 0 number of scarves we put 4 0's in a set of numbers. Then we see that there are 2 people who have 1 scarf. so there are 2 1's and we keep on going down the line.
{0,0,0,0,1,1,2,3,3,4,5,5} there are 12 numbers here
so we add up all of them
1+1+2+3+3+4+5+5=24
then divide that number by 12 because that's how many numbers there are
24/12=2
The mean of the numbers is 2
Hope that helps :)

John is 30 years old. He will receive two payments of $2500 each. The first payment will be an unknown number of years in the future. The second payment will be five years after the first payment. At an annual effective interest rate of I=5%, the present value of the two payments is $2606. Determine at what age John will receive the second payment.
Answer:
16 years
Step-by-step explanation:
Let us assume that he would received the first payment after t years
So
The following formula should be used
PV = P ÷ (1 + r)^t + P ÷ (1 + r)^t+5
$2,606 = $2,500 ÷ (1 + 0.05)^t + $2,500 ÷ (1 + 0.05)^t + 5
$2,606 = $2,500 ÷ 1.05^t (1 + 1 ÷ (1.05)^5)
1.05^t = $2,500 ÷ $2,606 (1.7835) = 1.71098
t = ln(1.71098) ÷ ln(1.05)
= 11
Therefore he would be received the second payment after
= 11 + 5
= 16 years

Find sin(a) in the triangle.
Choose 1 answer:
Answer:
5/13
Step-by-step explanation:
Find the diagram to the question attached
Given the following considering angle A
Hypotenuse = 13 = AB
Opposite = 5 (side facing the angle A) = BC
Adjacent = 12
According to SOH CAH TOA;
Sin theta = opposite/hypotenuse
Sin(a) = BC/AB
Sin(a) = 5/13
Hence the value of sin(a) is 5/13
There are twenty books on a shelf. Ten of them are science books, two are social studies, seven are math, and one is reading. What is the probability of choosing a science book, replacing it and then choosing another science book?
Answer: 1/4
Step-by-step explanation: Probability is favorable outcomes/ all outcomes, to first choose a science book, the probability is 10/20, or one-half, and then to pick one again, is also 1/2, so you multiply them together to find the probability of both happening and you get 1/4!

Step-by-step explanation:
its not c because if you look at R you see that it is going 4,3 not 3,4 because when you doing ratios on a number line it goes x-axis then y-axis next not y-axis then the x-axis.
It's not D because if you look at Q you see that it is going 3,5 not 5,3 because when you doing ratios on a number line it goes x-axis then y-axis next not y-axis then x-axis.

A private ship carries two types of cargo: large crates and extra-large crates. Each type of crate weighs a specific amount.
On Saturday the ship carried 400 large crates and 275 extra-large crates weighing 18,800 tons.
On Sunday, the ship carried 190 large crates and 335 extra large crates, weighing 16,100 tons.
How much does an extra-large crate weigh in tons?
F 25 tons
G 32 tons
H 30 tons
J 24 tons
Answer:
G. 32
Step-by-step explanation:
32 x 335 = 10720
16,100 - 10720 = 5380/190 = 28.3157894737
275 x 32 = 8800
18,800 - 8800 = 10,000/400 = 25 (This is the closer).
30 x 335 = 10,050
16,100 - 10,050 = 6050/190 = 31.8421052632
30 x 275 = 8250
18,800 - 8250 = 10550/400 = 26.375 (Same reason why it does't work)
25 x 335 = 8375
16,100 - 8375 = 7725/190 = 40.6578947368
25 x 275 = 6875
18,800 - 6875 = 11925/400 = 29.8125
24 x 335 = 8040
16,100 - 8040 = 8060/190 = 42.4210526316
24 x 275 = 6600
18,800 - 6600 = 12200/400 = 30.5

Answer:
√17 - 3 > -2 + √5The index rises 4.9% over the course of the day. What is the value of the index at the end of the day? Round your answer to the nearest hundred.
Answer: $70400
Step-by-step explanation:
Attached is the question:
Based on the information given in the question:
Value of Stock X = 5000 × $4.30 = $21500
Value of Stock Y = 2000 × $3.20 = $6400
Value of Stock Z = 8000 × $4.90 = $39200
Total Stock Value = $67100.
Since there's a 4.9% increase in value of index, the value of the index at end of the day will be:
= $67100 × (100% + 4.9%)
= $67100 × 104.9%
= $67100 × 1.049 =
= $70388
= $70400 approximately

Ahmed received a box of gifts. The box is a rectangular prism with the same height and width, and the length
is twice the width. The volume of the box is 3,456 in? What is the height of the box?
Answer:
12 inches
Step-by-step explanation:
Ahmed received a box of gifts. The box is a rectangular prism with the same height and width, and the length
is twice the width. The volume of the box is 3,456 in? What is the height of the box?
Volume of a Rectangular pyramid = Length × Width × Height
From the above question
Height = Width = x
Length = 2 × Width
Length = 2x
Volume = 3,456 cubic inches
Hence,
3,456 = 2x × x × x
3456 = 2x³
x³ = 3456/2
x³ = 1728
Cube root both sides
Cube root(x³) = cube root (1728 cubic Inches)
x = 12 inches
Therefore, the height is 12 inches
Width, Height and Length of rectangular prism are 12, 12 and 24 inch respectively.
Assume;Width of rectangular prism = a
Height of rectangular prism = a
Length of rectangular prism = 2a
We know that;Volume of the rectangular prism = (l)(b)(h)
Volume of the rectangular prism = (2a)(a)(a)
3,456 = 2a³
a³ = 1,728
a = 12 inch
So,
Width of rectangular prism = 12 inch
Height of rectangular prism = 12 inch
Length of rectangular prism = 2(12)
Length of rectangular prism = 24 inch
