Answer:

The correct option is A.

Step-by-step explanation:

Let the third vertex of the triangle be C and the angle C is 90 degree.

In a right angles triangle, the sine ratio is defined as

\sin \theta=\frac{perpendicular}{hypotenuse}=\frac{opposite}{hypotenuse}

Using sine ratio,

\sin A=\frac{BC}{AB}

\sin A=\frac{10}{26}

\sin A=\frac{5}{13}

\sin B=\frac{AC}{AB}

\sin B=\frac{24}{26}

\sin B=\frac{12}{13}

Since \sin A=\frac{5}{13} and \sin B=\frac{12}{13}, therefore the correct option is A.

The daily cost of hiring a plumber , y , to work x hours on a repair project can be modeled using a linear function. The plumber
Paladinen [302]

Answer:

The range of the function is 80\leq y\leq 440

Step-by-step explanation:

Consider the provided information.

The plumber charges a fixed cost of $80 plus an additional cost of $45 per hour.

Let plumber works for x hours, then the required linear function will be:

y=45x+80

The plumber works a maximum of 8 hours per day.

That means the minimum value of x is 0 and maximum value of x is 8.

We need to find the range of the function.

Range of the function is the set of y values.

Substitute x=0 in above function,

y=45(0)+80

y=80

Now substitute x=8 in above function.

y=45(8)+80

y=360+80

y=440

Hence, the range of the function is 80\leq y\leq 440

Mark all true statements. Group of answer choices
laiz [17]

Answer:

True

False

Step-by-step explanation:

a) The first statement is the basis for Euclid's algorithm to compute the gcd of two nonnegative integers a,b. You can prove this as follows.

Let G=gcd(a,b). Since r=a-bq and G divides a and G divides b, then G divides r. Now, G divides a and G divides r, hence G divides gcd(b,r).

On the other hand, since a=bq+r, and gcd(b,r) divides b and r, then gcd(b,r) divides a. Therefore gcd(b,r) divides a and b, which implies that gcd(b,r) divides G.

x divides y and y divides x implies that |x|=|y|. The GCD's are nonnegative, therefore G=gcd(b,r).

b) It is false. In general, to test for primality of N, you have to check that all primes smaller than N do not divide N. In this case, we have to check for 2,3,5,7,11,13,17,19,23,...

101 is prime, but this may be false in general. For example, consider N=13*11=143. N is not prime, and n is not divisible by 2,3,5, or 7.
