Use ABC to find the value of cos a. 24/7 7/24 7/25 24/25
ExtremeBDS [4]

Answer:

\frac{24}{25}

Step-by-step explanation:

using the cosine ratio;

\cos(\theta)= \frac{adjacent}{hypotenuse}

From the question, the side of the right angle triangle that is adjacent to the measured <a,(i.e BAC) is AC=24 and the hypotenuse is AB=25

This implies that,

cos(a)= \frac{24}{25}

The table shows all the possible outcomes for spinning the pointer of the spinner with four equal sized sections labeled 1–4 and
vladimir1956 [14]

Answer:

12.5%

Step-by-step explanation:

There are two types of spinners here and the outcome of them is independent. That means

P(odd number,C) = P(odd number) * P(C)

There are two odd numbers out of four numbers in the first spinner. The chance of odd number will be:

P(odd) = 2/(2+2)= 1/2= 50%

There are four letters and the desired outcome is C. The chance for C will be:

P(C)= 1/4= 25%

Then the chance will be:

P(odd number,C) = P(odd number) * P(C)

P(odd number,C) =50% * 25% = 12.5%

PLEASE HELP! I have a deadline tonight ,I have to get this done! thank you!!<br> Two questions (:
Viktor [21]
Both of your answers are correct. In the first equation, if you were to substitute 3 for x, because you have to do exponents first, you have 3^2, which is 9, and 9*6 =54. If you were to substitute -3 for x again you would have to do the exponents first which would be -3^2 which is 9, and 9*6 = 54. 

For the second question, if I substitute 0.75 for t, I get -9 + 18 + 7. This is equal to 16, and therefore the answer would be D. Hope this helps! :D. Let me know if you have questions about my explanation, and feel free to post more questions.

PLEASE HELP ITS MATH

Answer:

y=[-4]x+[10]

Step-by-step explanation:

For a line to be perpendicular to another it must have the reverse reciprocal of the opposite line, to find the reverse reciprocal you take your slope, flip the numerator and denominator, and multiply it by -1.

The slope \frac{1}{4} turns into \frac{4}{1} and is then multiplied by -1 to become \frac{-4}{1} which can be simplified down to: -4

Now that we know the slope we need the line to pass through a point, so we will use point slope form:

y-y1=m(x-x1)
Substitute in our slope and point values:

y-2=-4(x-2)

Now solve for y:

y-2=-4(x-2)\\y-2=-4x+8\\y=-4x+10

Then you will find that line y=-4x+10 runs perpendicular to y=\frac{1}{4}x-8 and intersects point (2,2).
