Which equation has the solution x = 3

I do not understand what do you mean

Answer:

x- intercept = - 8 , y- intercept = 4

Step-by-step explanation:

to find the x- intercept let y = 0 in the equation and solve for x

x - 2(0) = - 8

x - 0 = - 8

x = - 8 ← y- intercept

to find the y- intercept let x = 0 in the equation and solve for y

0 - 2y = - 8

- 2y = - 8 ( divide both sides by - 2 )

y = 4 ← y- intercept

Answer:

G. \( \frac{3.2}{2} = \frac{a}{8} \)

Step-by-step explanation:

Given that figure I and figure II are similar, it follows that the ratio of their corresponding side lengths are equal and the same.

Thus:

\( \frac{3.2}{2} = \frac{a}{8} = \frac{8}{5} = \frac{6.4}{b} \)

Therefore, the proportion that must be true is:

✔️\( \frac{3.2}{2} = \frac{a}{8} \)

Answer

The answer will be 8⁰

Step-by-step explanation:

Complementary angles always add up to 90⁰ degrees

Answer:

8 degrees (see explanation below)

Step-by-step explanation:

A complimentary angle is when 2 angles are added together to make a 90 degree angle. So if the measure of the current angle is 82, then the other measure is 8.

Answer:

Discriminant is 6.

Step-by-step explanation:

9-2x+3=0

-2x+9+3=0

-2x+12=0

-2x+12-12=0-12

-2x=-12

-2x/-2 = -12/-2

x=6

Answer:

The scale factor is the ratio of the corresponding side lengths in the original figure and the image.

If the image was created by reducing the size of the original figure, then the scale factor is less than 1.

If the image was created by enlarging the size of the original figure, then the scale factor is greater than 1.

The given options for the scale factor are "one half" and "two fourths".

"One half" is equivalent to 0.5.

"Two fourths" is equivalent to 0.5 as well (since 2/4 can be simplified to 1/2, which is 0.5).

Therefore, the scale factor used to create the image is 0.5 or one half, which suggests that the image was created by reducing the size of the original figure by a factor of 0.5.

Step-by-step explanation:

If X is a random variable representing the number of children that end up having light-colored eyes, then X follows a binomial distribution with success probability p = 0.25 and number of trials n = 5.

The variance of a binomial distribution with these parameters is n p (1 - p), so the variance in this case would be

5 • 0.25 • (1 - 0.25) = 0.9375 ≈ 0.9

The limit Lim x→1 (sinx - sin1)/(x - 1) = cos1

The limit of a function f(x) as x tends to a is the value of the function f(x) as x tends to a. It is written as \(\lim_{x \to a} f(x) = L\)

GIven that we require the limit given as  \(\lim_{x \to 1} \frac{sinx - sin1}{x - 1}\)

So, substituting the value of x = 1 into the given equation, we have that

\(\lim_{x \to 1} \frac{sinx - sin1}{x - 1} = \frac{sin1 - sin1}{1 - 1} \\= \frac{0}{0}\)

Since 0/0 is one of the inderterminate forms, we use the L'hopital's rule to find the limit of the given function.

L'hopital's rule states that if \(\lim_{x \to a} f(x) = \lim_{x \to a} g(x) = 0\) and f'(x) and g'(x) exist then \(\lim_{x \to a} \frac{f(x)}{g(x)} = \lim_{x \to a} \frac{f'(x)}{g'(x)}\)

Let the variables be

So, since we know that

\(\lim_{x \to 1} \frac{sinx - sin1}{x - 1} = \frac{0}{0}\),

So,  \(\lim_{x \to a} \frac{f(x)}{g(x)} = \lim_{x \to a} \frac{f'(x)}{g'(x)}\)

So, we differentiate both the numerator and denominator and find the limit.

So,

\(\lim_{x \to 1} \frac{f'(x)}{g'(x)} = \lim_{x \to 1} \frac{\frac{d(sinx - sin1)}{dx} }{\frac{d(x - 1)}{dx} } \\= \lim_{x \to 1} \frac{cosx - 0}{1 - 0} \\= \lim_{x \to 1}cosx \\= cos1\)

So, \(\lim_{x \to 1} \frac{sinx - sin1}{x - 1} = cos1\)

Step-by-step explanation:

Given:

\(-2(1-4x)=3x+8\)

Let's distribute the parenthesis

\(-2+8x=3x+8\)

Let's subtract \(-3x\) from both sides

\(-2+5x=8\)

Let's add \(2\) to both sides

\(5x=10\)

Now, let's divide both sides by \(5\) to get \(x\) alone

-2({\color{#c92786}{1-4x}})=3x+8−2(1−4x)=3x+8

−2(−4+1)=3+8

-2({\color{#c92786}{-4x+1}})=3x+8−2(−4x+1)=3x+8

2)

Distribute

−2(−4+1)=3+8

{\color{#c92786}{-2(-4x+1)}}=3x+8−2(−4x+1)=3x+8

8−2=3+8

{\color{#c92786}{8x-2}}=3x+88x−2=3x+8

Answer: any negative value

Step-by-step explanation:

g(x)= ax², inc on x<0 & dec on x>0

Firstly we need to get the derivative of g(x)

g'(x)=2ax

for inc interval g'(x) should be +ve

x<0 (i.e. x= -ve), then a must be -ve

for dec interval g'(x) should be +ve

x>0 (i.e. x= +ve), then a must be -ve

so in both cases a must be a negative constant

Answer:

14.7

Step-by-step explanation:

Let's say the width is x

So volume would be 24 × 2x × x = 10368

24 × 2x² = 10368

2x² = 10368 / 24 = 432

x² = 216 , width can't be negative so

x = 14.6969... ~~ 14.7

Answer:

$0.64 per cup

Step-by-step explanation:

There are 16 cups in 1 gallon, so the number of cups in 2 gallons is:

1 gallon: 16 cups

2 gallon = 2 x 1 gallon = 2 x 16 cups = 32 cups

So we need to find the price of each cup:

1 cup = ($20.48 / 32 cups) = $0.64 per cup.

The first sum is a geometric series:

\(1+\dfrac15+\dfrac1{5^2}+\dfrac1{5^3}+\cdots+\dfrac1{5^n}+\cdots=\displaystyle\sum_{n=0}^\infty\frac1{5^n}\)

Recall that for |x| < 1, we have

\(\dfrac1{1-x}=\displaystyle\sum_{n=0}^\infty x^n\)

Here we have |x| = |1/5| = 1/5 < 1, so the first sum converges to 1/(1 - 1/5) = 5/4.

The second sum is exponential:

\(1+5+\dfrac{5^2}{2!}+\dfrac{5^3}{3!}+\cdots+\dfrac{5^n}{n!}+\cdots=\displaystyle\sum_{n=0}^\infty \frac{5^n}{n!}\)

Recall that

\(\exp(x)=\displaystyle\sum_{n=0}^\infty\frac{x^n}{n!}\)

which converges everywhere, so the second sum converges to exp(5) or e⁵.

Answer:

False

Step-by-step explanation:

3√2 sec(theta) + 7 = 1

3√2 sec(theta) = -6

sec(theta) = -2/√2

sec(theta) = -√2

theta = arcsec(-√2)

However, the range of secant function is [-∞, -1] U [1, ∞]. Since -√2 is not within this range, we cannot take the arcsecant of -√2. Therefore, there is no real value of theta that satisfies the equation, including 3π/4.

Therefore, the statement "The value 3π/4 is a solution for the equation 3√2 sec(theta) + 7 = 1" is False.
