Answer:3

Step-by-step explanation:

Given

Quadratic equation is [tex]x^2-4+k=0[/tex]

if one root exceeds the other by two

suppose one of the roots is a, then the other is a+2

The Sum of roots is

[tex]=\dfrac{-\text{coefficient of x}}{\text{coefficient of }x^2}[/tex]

[tex]\therefore a+a+2=-\dfrac{-0}{1}\\\\\Rightarrow 2a+2=0\\\Rightarrow a=-1[/tex]

Product of roots

[tex]\Rightarrow (a)(a+2)=\dfrac{k-4}{1}\\\Rightarrow (-1)(1)=k-4\\\Rightarrow k=4-1=3[/tex]

Answer:

Area = 78.5 square feet

Step-by-step explanation:

Formula for area of a circle: A = pi r^2 or area = pi times radius squared

So the diameter = 10 feet

And radius is half of the diameter so radius = 5 feet

A = pi x 5 squared

A = pi x 25

A = 78.5 square feet

Answer:

A = 78.5 [tex]ft^{2}[/tex]

Step-by-step explanation:

A = π[tex]r^{2}[/tex]

diameter = 10

radius is half of 10 = 5

A = 3.14 x [tex]5^{2}[/tex]

A = 3.14 x 25

A = 78.5 [tex]ft^{2}[/tex]

Answer:

The expression is 300/t, , or 300 divided by t

Step-by-step explanation:

Answer:

(F-32) is negative (because 5/9 of that value is negative.)

F is less than 32. (since 5/9 is positive, whatever we are multiplying it by must be negative. a negative times a positive is a negative)

Step-by-step explanation:

It's NOT the last one, because multiplying anything by zero gives you the result of zero

And it's not the first, because there is one specific answer to this math problem.

Answer:

2.19888km

Step-by-step explanation:

C=2πr

Answer:

[tex] \approx \: 21.2 \: {ft}^{2} [/tex]

Step-by-step explanation:

[tex]central \: \angle = \frac{\pi ^{c} }{6} = 30 \degree \\ \\ area \: of \: the \: sector = \frac{30 \degree}{360 \degree} \times \pi {(9)}^{2} \\ \\ = \frac{1}{12} \times 3.14 \times 81 \\ \\ = \frac{1}{12} \times 254.34 \\ \\ = 21.195 \: {ft}^{2} \\ \\ \approx \: 21.2 \: {ft}^{2} [/tex]

Answer:

given

π6radian=30°

radius r =9ft

the area of the sector=30°/360×π×r²

=30/360×22/7×9²=21.214ft²

i dont what the answers are but this is the answer to the expression

Answer:

x = 10.43

Step-by-step explanation:

use tan:

⇒ tan = [tex]\frac{opposite}{adjacent}[/tex]

⇒ tan 41 = [tex]\frac{12}{x}[/tex]

tan of 41 is 0.869

⇒ 0.869 = [tex]\frac{12}{x}[/tex]

multiply each side by 12

⇒ 0.869 x 12 =[tex]\frac{12}{x}[/tex] x 12

x = 10.43

Answer:x = 10.43

Answer:

[tex] \sqrt{b {}^{2} + (c - a) {}^{2} } [/tex]

Answer:

1.50x + 1.25y = 375

Step-by-step explanation:

x = beverages

y = candy

1.50x + 1.25y = 375

The equation that can be used to model the different numbers of beverages and candy that can be sold to meet the goal is 1.50x+1.25y=375.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the number of beverages sold be x, while the number of candies sold is y.

Given that the selling price of a beverage is $1.50, while the selling price of candy is $1.25. Also, the total amount that is needed to be raised is $375. Therefore, the total cost can be written as,

[tex](\$1.50 \times x)+ (\$1.25 \times y) = \$375\\\\1.50x+1.25y=375[/tex]

Hence, the equation that can be used to model the different numbers of beverages and candy that can be sold to meet the goal is 1.50x+1.25y=375.

Answer:

13.5

Step-by-step explanation:

first let's subtract 6.00 from 6.00 and 26.25

26.25-6=20.25

1.50(m)=20.25

so we need to get rid of the 1.50

so 1.50m divided by 1.50=m

20.25÷1.50=13.5

m=13.5 hope this helps
