What is the distance to the earth’s horizon from point P?

Enter your answer as a decimal in the box. Round only your final answer to the nearest tenth.
x = mi
A circle representing earth is shown. The center of the circle is labeled earth's center. From the center, a radius labeled 3959 miles goes up and to the right until it touches the circle. This radius extends outside the circle to point P. The segment on the circle out to point P is labeled 5.9 miles. A line segment is shown that goes from point P vertically downward until it stops at the farthest right point on the circle and is labeled x. From the farthest right point of the circle, a line segment is drawn horizontally to the center of the circle and is labeled 3959 miles.

Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x^2 - 23 = 10x a. -1.93, 11.93 b. 1.93, -11.93 c. 1.93, 11.93 d. -1.93, -11.93

According to a research study, parents with young children slept 6.4 hours each night last year, on average. a random sample of 18 parents with young children was surveyed and the mean amount of time per night each parent slept was 6.8. this data has a sample standard deviation of 0.9. (assume that the scores are normally distributed.) researchers conduct a one-mean hypothesis at the 5% significance level, to test if the mean amount of time parents with young children sleep per night is greater than the mean amount of time last year. the null and alternative hypotheses are h0: μ=6.4 and ha: μ> 6.4, which is a right-tailed test. the test statistic is determined to be t0=1.89 using the partial t-table below, determine the critical value(s). if there is only one critical value, leave the second answer box blank.
